Miners take hands-on approach to power shortages


More mining groups are being forced to build their own power plants, sending a few into the utility business and making the whole sector into astone crusher equipment price more complex investment proposition. Volatile global oil prices and power shortages in nations such as South Africa have lifted the importance of electricity for mining companies, curbing growth plans and boosting costs.


Miners have had to take more of a hands-on approach to power as their quest for big deposits has taken them to remote areas of the globe that are deficient in electricity. Mining groups Xstrata and Anglo American are working on feasibility plans to use waste coal in South Africa to fuel generation plants, Rio Tinto has plans for hydropower plant in Cameroon while copper producer Kazakhmys has become the biggest power generator in its home market of Kazakhstan. "I guess there's a power supply problem in all emerging markets and miners are having to go to off the beaten track to try to find resources," said analyst Tom Gidley-Kitchin at Charles Stanley in London...

Marble Production in District Lasbela


Marble can be a metamorplric rock formed by re-crystallization of limestone or dolornitic limestone. It is normally medium to fine grained and white colored, with a variety of shades, shapes or spots and is also able to take on an excellent polish. Marble is really a durable stone in dry atmosphere when protected against rain. The surface of marble crumbles readily when subjected to moist or acid atmosphere. Purest kind of marble is statuary marble, which is white with visible crystalline structure. The distinctive luster of statuary marble is caused by light penetrating a brief distance into the stone after which being reflected from the surfaces of inner crymorden hollow block maiking machines in worldstals.


Marble is used like a monumental stone in buildings, sculptures, and ceramic tiles. Inside the dimension stones trade, limestone can also be classified under marble. Commercially the phrase marble is extended to contain any rock consists of calcium carbonate which takes polish, which includes ordinary limestone. The term is further extended within the loose designation of stones like alabaster, serpentine along with other soft rocks. Specific gravity of marble ranges amongst 2.68 to 2.72, which determines density from the stone.


Marble Production in District Loralai


Different kinds of marble mined in District Loralai includes. Botesina cream. Botesina Rabbit. Botesina Fancy, Malaysia, Loralai white, Micro Botesina. Super White. Super Ziarat. Sunjavi Botesina. Bargar Botesina. and Ziarat Mix red etc.


Some of the marble bearing regions contain, Kasa. Karru. Gaza. Matwarkh. Mula Shahu. Sunavva. Bargar. Barhadh. Shabozai. Tora Tana, sapadar. Kach Amagzai. Injeergut. Pathan Kot. Chothar & Nana Sahib (Duki).


There are about 19 marble processing unites (3-under construction) inside the district.


Marble Production in District Khuzdar


District Khuzdar district is rich in marble deposits with various varieties & colors. These varieties contain China Verona. Botesina. Humza Green or Amber Green. Plane Verona. King Gold. Marina Pink & Burma Teak. These varieties are abundantly available and also have great value in the local along with inside the international markets.


Total quantity of marble processing unites within the area are 06. i.e. two processing unites at District Khuzdar and four at Xaal.

Mining: Diverse equipments are used for extracting M&G at mining sites. Presently very primitive and small equipments are being used for mining like trolley, pickaxe, bars, hammers, spade, tripod chain pulleys, wenches along with other small tools. Additionally, uncontrolled blasting is also getting used for M&G extraction. Some mine owners in Chaghi. Dalbandin & Kukundi locations use modern mining machinery like wire saw (imported from Iran & Italy). Splitters. Bulldozers, Cranes, Loaders, Generators and Compressors and so forth.


Raw Block Cutting: Irregular blocks arrive at marble & granite-processing units in different parts in the country where these irregular blocks are cut into large slabs using gangsaws and HV Cutters. These slabs within the next phase are cut into tiles strips, table and Kitchen tops and so forth. Onyx is cut into regular blocks at the mining site with the aid of modern machinery.


Cutting: The slabs at the plant are cut by small cutters and sizers into demanded sizes of tiles, strips, tabletops and kitchen tops etc. Once cut into the required shape the products are sent for that finishing and polishing process.


Polishing & Finishing: The slabs, tiles, strips and table/kitchen tops are finished and polished based on the industry standards and so are made ready for delivery. Usually manual polishing machines are used. In Dist. Loralai polishing is not done since most in the material is distributed to Punjab and so cut into thick tiles to prevent damage.


Sales & Distribution: The finished M&G items are now ready available on the retail shops or are provided for the building site as needed by the customers. Usually marble & Granite goods are sold in the factory showrooms where all the available varieties are displayed. Those needed for export are packed and shipped accordingly.


South African Gold Miners Post Worst Three-Day Drop in 21 Months


South Africa’s gold mining index posted its biggest three-day retreat in more than 21 months in Johannesburg trading as gold tumbled to beltrack mounted jaw crushers built in chinaow $1,600 an ounce and headed for the biggest two-day drop in a month.


The FTSE/JSE Africa Gold Mining Index declined 1.4 percent by 11:43 a.m. in Johannesburg, taking its losses for the past three days to 7.7 percent, the steepest since December 2009. AngloGold Ashanti Ltd. (ANG), Africa’s biggest producer of the metal, dropped 0.9 percent. Gold Fields Ltd. (GFI), the world’s fourth- biggest gold producer, slumped 1.3 percent. Commodities fell on speculation European governments will struggle to contain the region’s debt crisis that has pushed Greece on the brink of default. That threatens to tip both the region and the global economy back into recession even as Group of 20 finance chiefs pledged “a strong and coordinated international response to address the renewed challenges facing the global economy” at International Monetary Fund and World Bank weekend meetings. “Over the last six to 18 months or so gold was riding on the back of fears of macro economics in the U.S. and Europe.

Rio flags $US5.2b expansion


Rio Tinto has defied the economic gloom being talked up by arch rival BHP Billiton after today approving a $US5.2 billion investment in its Pilbara iron ore business.


Signed off by Rio&rused coarse ore crushing plant pricesquo;s board, which is meeting in London, the investment will push Rio’s Pilbara production capacity to 353 million tonnes a year by the first half of 2015.


Rio is producing iron ore at a rate of 230mtpa and had already approved investment to boost output to 283mtpa.


Although the board sign-off had long been talked of, today’s confirmation ends speculation that Rio too would adopt a more cautious approach about the global iron ore market.


BHP has taken a decidedly negative view of medium term global growth while flagging that it would press the go-slow button on a raft of mega-projects, including the Port Hedland outer harbour development which is crucial to the growth ambitions of its own iron ore division.


Sharemarket investors are also increasingly cautious, as evidenced by the fact that the share prices of Rio and BHP are trading around three-year lows. At the heart of investor concern is that the European debt crisis will have a huge impact on China’s export industries, at the same time as signs are emerging that China’s internal growth is slowing.


Any significant slowdown in economic growth in China could have a big impact on demand for sea-borne iron ore, which is largely the reason BHP is hesitating to push ahead with the costly Port Hedland outer harbour.


In a statement today, Rio Tinto Iron Ore chief executive Sam Walsh said the miner continued to see “positive prospects for medium to long-term iron ore demand driven by ongoing growth in Chinese consumption”.


“We continue to forecast that annual Chinese steel production will grow from its current level of around 700 million tonnes to around one billion tonnes a year out towards 2030,” Mr Walsh said.


“This demand growth is coupled with an increasingly challenged supply response, as several high-profile competitor projects have recently been either delayed or postponed.”


Underpinning Rio’s faith in iron ore, the miner today also announced a further $US1 billion investment to advance its Simandou joint venture in Guinea, West Africa. Rio is developing Simandou with China’s Chinalco.


Rio Tinto shares were up 85 cents, or 1.5 per cent, to $57.62 by 1.25pm.

Construction and Demolition Waste Recycling

In Ontario, there's only one particular gypsum recycling facility: New West Gypsum Recycling Inc. (New West Gypsum Recycling, N.D.) in Oakville2. As a result, the wastes generated far from this recycling facility, specifically in the northern component of Ontario, would go to landfills3 (Recycling Council Ontario, 2005). As well as this location condition, the balance among the recycling tipping fee of 57.five CAD (Radvanyi, 2007) and also the landfill tipping fee4 very influences the waste generator's choice of the way to dump waste. Inside the case of C&D wastes, a number of the wastes generated in Ontario are presently brought to the landfills in Michigan (RIS International Ltd., 2005).


At this point, it ought to be noted that although the location along with the quantity of recycling facilities are important factors for the level of the recycled gold mining equipment australiamaterials and the balance between haulage and greenhouse gas emissions, increasing the variety of recycling facilities is not the crucial condition that accelerates recycling. For example, although Japan has 293 business offices which have one with the facilities for breaking, crushing, separating, and sorting the waste gypsum board (Ministry of Environment Japan, 2002), the recycling issues surrounding waste gypsum board have not been solved yet.



On the other hand, some jurisdictions including the Vancouver area in British Columbia experienced negative consequences dumping gypsum in landfill sites and they've banned the landfilling of gypsum board. Specifically, biological and chemical reactions from your generation of hydrogen sulfide gas emitted from the buried gypsum board can often causes odours and also human death. In 2000, 3 individuals who worked at a final disposal facility died due to hydrogen sulfide gas in Japan. It's estimated that gas was released from your buried wastes containing CaSo4 which comes from gypsum board (Secretary of state for Environment Japan, 2000).


Recycling technology


The recycling process of gypsum board is really as follows.



  • 1) Separate gypsum board using their company building materials.

  • 2) Store gypsum board in a transfer station, then transfer it to some recycling facility.

  • 3) Separate gypsum from your paper and take away fasteners and other attachments.

  • 4) Gypsum is chipped or pulverized after which coupled with raw gypsum for new products.


In these processes, there's two main barriers to recycling gypsum board. The very first is the separation of gypsum board off their building materials that you can do on-site. Mentionened above previously in Section 3.1, gypsum board is widely used for interior walls and as a base for tiles, and it is combined with many other materials. However, limited recognition with the need for its separation and a lack of space for the bins prevent separation of gypsum as well as other building materials on-site. Proper source separation will keep value like a material for recycling by reduction of contamination. Due to these damages, the waste gypsum board from demolition sites is much harder to recycle than the a single from construction sites. While almost 100 per cent of gypsum board waste from your construction sites is recycled by the gypsum board manufacturers in Japanese urban centers such as Tokyo, only the waste gypsum board from demolition sites is under 1 tenth with the recycling from construction sites (Nishi, 2007a).


Some say source separation has not been implemented since it is time-consuming and labor intensive, and it affects the price of recycled materials. However, it requires the same period of time to grab gypsum board and set it inside a bin in any case. For that reason, source separation only depends upon a place for bins along with the environmental concern of waste generators.


The second barrier will be the treatment on gypsum board including water resistance covering and paint, particularly on the papers which cover the gypsum (Willow Root Environmental Limited, 2000). However, this constraint is dependent upon the share of gypsum board with treatment within the market. For instance, gypsum board with surface treatments can be recycled in Japan where 80 per cent from the all gypsum boards are regular boards and also the influence from the treatments is really as small (Nishi, 2007a).


Construction And Demolition Waste Recycling


Construction and demolition (C&D) materials contain the debris generated throughout the actual building, renovation, and demolition associated with buildings, roads, and bridges. C&D supplies often contain bulky, heavy supplies, for example concrete, wood, alloys, glass, and salvaged building elements.


Reuse and Recycling - How should we safely cope with the resulting rubble and waste?


Recycle and recycling of C&D materials is a single element of a more substantial holistic practice called sustainable or green building building. The efficient usage of resources is often a fundamental tenet of green creating building. What this means is reducing, reusing, and recycling most otherwise all materials that remain carrying out a building or renovation project. Green building building practices range from salvaging dimensional lumber in the actual project, using aggregates reclaimed through crushed concrete, or grinding drywall scraps to use on site just like a soil amendment.


At in conclusion of a building's life, demolition generates huge amounts of materials which may be reused or recycled, principally wooden, concrete as well as other types connected with masonry, and drywall. Rather than demolish a complete building, consider "deconstructing" all or the primary structure. Deconstruction is the organised dismantling building components for recycle or recycling. In contrast so that you can demolition, where buildings are bumped down and materials are possibly landfilled or recycled, deconstruction involves carefully taking aside areas of buildings or removing their contents while using primary goal being reuse. It might be as simple as stripping away cabinetry, fixtures, and windows, or even as involved as manually getting apart the building frame.


Mobile Crusher For Concrete Recycling


The actual Mobile Crushing plant produces cement hardcore, which can be saved on-site for future utilize, cutting the expenses of site redevelopment and eliminating the necessity for transport - further benefiting the planet.



There are lots of valuable resources on clients' sites that folks might help them plan so that you can store and re-use for website redevelopment. One particular of the very most typical is concrete. ZENITH runs its mobile concrete crushing plant allowing on-the-spot recycling of concrete supplies reclaimed during controlled demolition.


The entire process is managed for an individual, from crushing to handling to safe stockpiling of your reusable resources.


Wilcherry Hill iron ore shipments a step closer after South Australian Government approval


silica sand washing plants

IronClad Mining has taken another step towards utilising the cash generating potential of the company's new Wilcherry Hill mine.


The South Australian Government has now approved the development application for port facilities designed for iron ore shipments from the project. A major plus for Wilcherry Hill is that the first two years of production from the project has been contracted for sale to international steel mills under comprehensive sales and marketing agreements. Additionally, 50% of year three and four’s forecast production has been contracted for sale through an off-take agreement with Hong Kong based company New Page Investments Limited. Stage one at the project includes the production of 1 million tonnes per annum of direct shipping ore magnetite, which will double in the second year of operation. Wayne Richards, managing director, commented on the positive development news for the company: “We are most appreciative of the South Australian Government’s expeditious approval of this Development Application for another vital piece of...

Uranium Mining Project posed to destroy one of world's last wildlife heritage in Tanzania


A uranium mining conglomerate will be allowed to exploit the precious Selous Game Reserve in Tanzania after the World Heritage Committee (WHC) decided, at its July 2012 session in Russia, to accept what was described as a "minor boundary change" of the site. The change had been requested by the Government of Tanzania, in order to make way for the development of a major uranium mine, Mkuju River Uranium Project, owned by Russian ARMZ and Canadian Uranium One,


The decision to verti mill for dry fly ash grinding chinaallow the boundary change would allow the Mkuju River uranium project, situated in the South of the Selous Game Reserve at its transition to the Selous Niassa Wildlife Corridor, to go forward.


The Tanzanian Government lobbied heavily for the boundary change, after declaring its intent to " win the battle" against the UNESCO WHC.


Dozens of environmental groups around the world, many of them members of the German-based Uranium Network, decried the WHC decision which could lead to the creation of 60 million tons of radioactive and poisonous waste by the mine during its 10-year lifespan (139 million tons if a projected extension of the mine should be implemented). The radioactive wastes pose a serious threat to Selous Game Reserve which is home to the world’s largest elephant population and other wildlife. No proven methods exist to keep the radioactive and toxic slush and liquids from seeping into surface waters, aquifers or spreading with the dry season wind into the Reserve.


It remains completely unclear how the company or the Government of Tanzania will guarantee that the impact of millions of tons of radioactive and toxic waste will be “limited”. The WHC decision appears to be influenced by heavy corporate and government lobbying and not by sound science. It sets a horrible precedent that could threaten other World Heritage Sites with similar dangerous and damaging exploitation.


The decision is in stark contrast to previous decisions of the WHC of 2011 stating that mining activities would be incompatible with the status of Selous Game Reserve a World Heritage site.


The environmental groups question whether WHC members have fully understood and given adequate attention to the implications of a uranium mine - including diesel generators, uranium mill, housing, heavy truck roads, as well as the creation of millions of tons of radioactive and toxic waste which should be contained safely and separate from the environment for thousands of years.


Uranium mining creates radioactive dust, contaminates waterways and groundwater aquifers and depletes often precious water supplies. Once abandoned, the radioactive contamination from the mines can persist for decades or even hundreds of years.


The WHC's decision was made at a time when Russia was chairing the WHC session in St. Petersburg, Russia; Mkuju River uranium project - which basically lives or dies with the decision on the boundary change - is majority owned by Russian ARMZ, a subsidiary of ROSATOM - who bought it from Australian Mantra Resources earlier in 2012.


The environmental groups urge the World Heritage Committee to reconsider its decision on the Selous Game Reserve Boundary Change and call upon the Government of Tanzania to refrain from licensing a uranium mine in Selous Game Reserve or on lands cut out from it.

Tony Sage sees Cape Lambert as infrastructure play in West Africa


Cape Lambert Resources plans to be a West African infrastructure play in two years to cashks the start up factor coveyor-in on the rapid interest in the emerging region.


Perth businessman Tony Sage wants his investment vehicle to be generating about $US250 million ($240.5m) each year from its iron ore assets, and is targeting a railway line from the group’s Sierra Leone project as the main revenue driver. Mr Sage said he is often criticised by investors about long-term earnings because his strategy is not to become a producer but to instead sell exploration projects. But he has argued that, with deals to earn iron ore royalties from three West African projects and about $US400m in the bank, the strategy will be enhanced by building and owning infrastructure in an iron ore province he calls the next "Pilbara". "If you own the infrastructure, you control the...

Local officials accused of illegal mining in Zamboanga


A large-scale mining operator in Zamboanga del Sur accused local officials of engaging in illegal mining in Balabag Village in the hinterlands of Bayog town, as well as trying to discredit the company by sending fake emailssecond hand mining equipment japan price to the president, other top government officials, government agencies, the military, police and the media.


“The local officials are among the illegal miners,” TVI Resource Development Public Affairs Director Gene Gregorio told reporters in a news briefing on Monday.


“These are also the same people and the same groups involved in the peddling of lies to demonize the name of the company and besmirch the reputation of its top officials and even harass them,” Gregorio added.


Gregorio, however, refused to name the local officials whom they accused of conspiring to control the mining operations in the area.


The TVIRD is a publicly-listed Canadian company involved in the production, development, exploration and acquisition of resource projects in the Philippines. It produces copper and zinc concentrates from its Canatuan mine, it pre-develops its Balabag gold and silver project, and carries out exploration programs on its other North Zamboanga tenements. It also has an interest in an offshore Philippine oil property.


TVIRD’s Canatuan mine is the first foreign-invested mine to reach production stage after the passage of the Philippine Mining Act of 1995 and is operated by TVI Resource Development (Phils.) Inc.


But in a telephone interview, Bayog Mayor Leonardo Babasa said while the TVIRD’s accusations may be true, the company’s spokesman should have identified the officials involved in illegal mining.


“That was unfair. When they say local officials, that’s already generalizing. We have many officials here. I am for one is not involved in anything illegal in my jurisdiction and I am also an advocate of responsible mining, whether large-scale or small-scale,” said Babasa, who also verified reports that thousands of people have descended on his town in search of gold.


Babasa said that responsible mining simply means that mining operators should follow the law and secure permits before they start their operation.


The mayor, though, admitted that at least two Sangguniang Bayan members or councilors are indeed involved in illegal small-scale mining in his town.


“It’s an open secret here. Some local officials are involved,” said Babasa, who did not identify the councilors.


Babasa said small-scale mining have been going on in the area since the early 90s, way before the TVIRD secured an agreement with the provincial government and the Department of Environment and Natural Resources.


Babasa warned, though, that the “situation is more serious than what it appears, and there are people whose lives are in danger.”


The TVIRD, which owns several Mineral Production Sharing Agreements issued by the DENR covering mining areas in Canatuan, Siocon in Zamboanga del Norte and in Bayog, Zamboanga del Sur, said that illegal mining operators have resorted to employing sophisticated and creative’ modes to destroy the company.


The TVIRD said that a series of emails were circulated early this year implicating the company’s executives in a murder conspiracy against certain illegal miners in Balabag, Zamboanga del Sur.


“It was a clear dirty-tactics operation using fake emails to criminally misrepresent TVIRD and mislead President Simeon Benigno S. Aquino III, and other top government officials including Environment and Natural Resources Secretary Ramon Paje and other Cabinet secretaries, heads of government agencies including the National Security Commission, private institutions, military and police officers, the media, our stakeholders and communities where we operate.”


The deluge of emails prompted the TVIRD to seek assistance from the National Bureau of Investigation and international private risk assessment and security agency Pacific Strategies and Assessments, to separately run a check on the authenticity of the emails.


After a thorough investigation, the NBI and the PSA both said there was indeed a plot to influence top officials of the government and agencies against TVIRD.


“The emails did not come from the authentic source (TVI) and are maliciously created,” said NBI Agent Francis V. Senora in his report dated July 13.


The PSA also branded the emails as “spurious” after making its own analysis. Its managing director Scott Harrison said they examined 48 emails that were all declared “fraudulent.”


“A number of the “Suspect Documents” were copies of actual TVI emails that had been fraudulently amended from their original text,” the PSA said. None of those “Suspect Documents” were generated from within the TVI IT systems.”


Both the NBI and the PSA noted defects in the emails that made them question their authenticity, including inconsistencies between the graphic interphase in the email printouts and the real or actual emails of TVIRD from its email system and provider; significant differences in domain addresses used in the fake emails and with real TVIRD emails, inconsistencies with tem stamp formats and other email protocols used in the fake and real emails and language syntax and even grammatical inconsistencies.


TVIRD company lawyer Fulgencio Factoran strongly denied that TVIRD and its officials were involved in any criminal acts.


“We are a legitimate, multi-million dollar publicly listed business. Our business practices here and in various parts of the world are beyond reproach,” he added.


On July 27, 2012, Factoran said TVIRD officials led by its president Eugene Mateo filed with the Makati Prosecutor’s Office charges of libel and falsification of documents against Bayog Municipal Councilor Julieto Monding, Edgar Baling, and Joel Cayabyab

Simmers production up 34%


Junior gold miner Sitrituradoras de arboles en mexicommers & Jack Mines (Simmers, SIM) on Tuesday reported a 34% rise in gold production from its Tau Lekoa and Buffelsfontein Gold Mine (BGM) to 49,170 ounces for the quarter ended December 2010 from 36,608oz in the September quarter.


This performance was largely due to Simmer's materially reducing general costs and increasing production at sustainable grades, it said. Gold revenue increased from 327 million rand for the quarter ended September 2010 to 463 million rand, with nearly half of the increase due to increased volumes, while 17.9 million rand was due to a 5% increase in the rand gold price per kilogram. Average underground grade increased from 3.21g/t last quarter to 3.54g/t. CFO and Interim CEO Marius Saaiman described the performance as “solid”. He said the increased production was largely as a result of accounting for Tau Lekoa for the full quarter, but is also due to the group's focus on operating efficiencies, sharing operational benefits between its two operations and good cost control.

Tanzania seen raising royalties on gold by year


Tanzania plans to raise royalty payments on exports of gold bcrushing plant manufactuered in pakistany the end of this year as it seeks to restructure the mining sector, Minerals and Energy Minister William Ngeleja said on Wednesday.


Africa's fourth-largest gold producer has been undertaking major reforms of its mining sector following growing criticism over the industry's relatively minor contribution to economic growth. Tanzania's annual gold exports have tripled to $1.5 billion in the past five years as gold prices have risen, but government revenues have remained at around $100 million a year. "We have already basically reached agreement with mining companies on raising royalty payments ... we expect migration to the new rates to start this year in 2011," Ngeleja told a news conference at a mining and energy conference in the northern Tanzanian town of Arusha. "The Ministry of Finance and the Tanzania Revenue Authority (TRA) are finalising the procedures for that." Tanzania initially planned to...

PanTerra Gold Upgrades to Las Lagunas plant to improve gold, silver production


PanTerra Gold is focused on improving the rate and density of feed to the Albion carbon in leach processing plant at the company’s Las Lagunas Project in the Dominican Republic.


The company began productcrusher for iron ore in karachiion at Las Lagunas in May, using high grade refractory tailings from the Pueblo Viejo mine.


Operations at Albion have been functioning as expected since then, however they have been temporarily suspended to allow for upgrades to the plant.


The plant will be restarted following the installation of a bucket wheel dredge this week, to provide consistent material density and optimise the efficiency of the plant.


As a result of the shut down, dore production will be delayed from its expected start in mid-June.


Dore will comprise 10% gold and 90% silver, and Las Lagunas is expected to produce about 69,000 ounces of gold and 630,000 ounces of silver per annum.


The Las Lagunas project is expected to generate free cash flow of nearly US$100 million within 18 months, in addition to repaying Macquarie Bank’s $37.5 million project loan.


Another bonus for PanTerra is the company will recover its investment in the project of around $90 million to 30 June 2012 under the profit sharing agreement with the Dominican Republic Government.


The Government will then receive 25% of operating profits, but PanTerra will not pay any income tax on its profits.


At a gold price of around US$1,400 per ounce and a silver price of about US$28 per ounce, Las Lagunas could generate around $300 million in surplus cash over the next six and a half years.

Coobina chromite mine set to re-open


Ukrainian billionaire Gennadiy Bogolyubov is poised to reopen the Coobina chromite mineabn amro gold mine cost report q2 2008 in the Pilbara, creating 120 jobs for an operation that could generate about 2.5 per cent of the world's supply of the stainless steel ingredient.


The billionaire, who picked up Coobina as part of his $1.2 billion takeover of Consolidated Minerals in late 2007, expects the resumption of mining at Coobina will cost about $6 million. Coobina, east of Newman, is Australia's only chromite mine. The Coobina open pit mine has been on care and maintenance since 2008 when the global financial crisis triggered a collapse in stainless steel production. About 20 people have remained on site to work on the crushing and beneficiation plant, with another 100 needed to support the reopening of the mine by October. Mr Bogolyubov expects Coobina to produce up to 450,000 tonnes of chromite a year, equivalent to about 2.5 per cent of an annual world supply estimated at 18 million tonnes.

BHP Billiton Approves Caval Ridge Mine Project


BHP Billiton today approved development of the Caval Ridge Mine project and expansion of the Peak Downs Mine in the northern Bowen Basin in Central Queensland, Austrmining equipment southern africaalia. The initial project will add 8 million tonnes per year capacity (100 per cent basis) in export metallurgical coal, with the expectation of a rapid, low cost expansion to 10 million tonnes per year. This additional 2 million tonnes per year will only require the addition of mining equipment. This expansion has not yet been permitted.


The total investment in the initial project is US$4.2 billion, of which BHP Billiton’s share is US$2.1 billion. The resource life of the initial project is expected to be greater than 60 years1. First coal is expected in calendar year 2014.


The new Caval Ridge Mine will have the capacity to produce 5.5 million tonnes per year. The Peak Downs Mine will expand production by 2.5 million tonnes per year. The investment will include construction of a new coal handling and preparation plant at Caval Ridge to process production from the Caval Ridge Mine and Peak Downs expansion. Coal from the Peak Downs expansion will be transported by conveyor to the new plant. The Peak Downs Mine lies to the immediate south of the new Caval Ridge Mine.


The Caval Ridge Mine will be an open cut dragline and truck and shovel operation, with coal railed to the BHP Billiton Mitsubishi Alliance (BMA) Hay Point Coal Terminal. The project has received all necessary regulatory approvals.


BHP Billiton Metallurgical Coal President, Hubie van Dalsen, said: “This investment in the Caval Ridge Mine was foreshadowed in March of this year when BHP Billiton announced investments in the new 4.5 million tonne per year Daunia mine, the life extension of the Broadmeadow mine and the 11 million tonne per year expansion of the Hay Point Coal Terminal.


“This is a continuation of BHP Billiton’s strategy of investing in large, low cost, expandable mines with long lives. Additional expansion projects are being advanced to follow this investment in due course,” he said.

Colorado Goldfields acquires Silver Wing Mine with $200 mln estimated total resource


Coloradmay san xuat bot barite cua trung quoco Goldfields on Wednesday announced that on May 16, 2011 it entered into a Purchase Agreement to acquire Silver Wing Mine. The properties consist of 10 patented mining claims across 70 acres in San Juan County in southwestern Colorado known as the Silver Wing Mine.


"A thorough study of geological structures, past production, core drilling and extensive underground sampling records indicates that the total resource of the Silver Wing Mine could exceed $200 million with approximately 80% of the resource value composed of silver and copper minerals," stated Lee Rice, President & CEO for Colorado Goldfields. The mine's poly-metallic ore contains recoverable metal values in gold, silver, lead, copper and zinc. Colorado Goldfields will develop a mining and milling operation and produce approximately 14,500 tons annually of gold, silver, copper, lead and zinc concentrates. After 1-year of ramp up work, production could reach 180 tons per day with full production of 360 tons per day achieved after two years. The initial ore discovery and location for the first Silver Wing Mine was made in 1874 on the Silver Wing claim itself...
