Manganese Mining

Manganese Crusher Introduction

Manganese crusher is the stone crusher or rock crusher used for crushing manganese mineral materials in mining industry. Manganese crusher is used widely in the USA, India, Russia, Malaysia, and European countries etc. According to the manganese crusher application, crusher can supply you jaw crusher , cone crusher, impact crusher, and mobile crusher equipments in manganese crushing plants or manganese production lines etc.

What is manganese

Manganese (Mn) is a hard, silvery white metal with a melting point of 1,244 °C (2,271 °F). The two main manganese minerals are pyrolusite (MnO2) and rhodochrosite (MnCO3). Manganese is the fourth most used metal in terms of tonnage after iron, aluminium and copper.

Ordinarily too brittle to be of structural value itself, it is an essential agent in steelmaking, in which it removes impurities such as sulfur and oxygen and adds important physical properties to the metal. For these purposes it is most often employed as a ferromanganese or silicomanganese alloy; as a pure metal it is added to certain nonferrous alloys.

the second most important market for manganese in the form of electrolytic manganese dioxide is dry cell batteries. Manganese also is an important alloying element in aluminium and copper, is used in plant fertilisers and animal feeds and is a colorant.

Manganese Ore crushing plant

World Manganese Production, Reserves, and Reserve Base

Over 80% with the recognised planet manganese means are discovered in South Africa and Ukraine. Other significant manganese deposits are in China, Australia, Brazil, Gabon, India, and Mexico. the usa imports manganese ore mainly because the manganese means within the U.S. are fairly reduced in manganese articles every lot of ore. Importing these ores is presently much more financial than mining them locally.

Most manganese ore imported towards United States is employed to manufacture intermediate manganese ferroalloy products and services and electrolytic manganese for use in dry-cell batteries. Only a little quantity with the ore is straight employed within the metal producing process.

Some manganese is recovered via the reprocessing of scrap metals and metal slag, or even the components left more than in the steel-making process. although regarded as spend in conditions of its metal content, slag usually consists of substantial quantities of other components that may be recovered.

Manganese crushing plant

The first step of getting manganese is crushing in manganese ore processing plant. So the manganese ore crusher is very important mining equipment in manganese ore processing plant.

The complete manganese crushing plant consist of jaw crusher as primary crusher, cone crusher as fine crusher, and vibrating screen as screening machine using to screen out the suitable manganese ore.

crusher is a manufacturer of crushers and grinding mills in China, supplies all kinds of ore crushers, such as iron ore crusher, copper crusher, chromium crusher, manganese ore crusher for sale with best price, etc. Our products has exported to many countries such as USA, India, Brazil, Ghana, South Africa, Australia, Gabon, and received high popularity.

Manganese Ore Processing Plant

A method for processing raw manganese nodules for the selective recovery of nickel, copper, cobalt and zinc values contained therein, by predominantly hydrometallurgical means, comprising:

1. suspending the raw nodules, which have been comminuted to particle sizes less than 10 mm, in water or dilute wash solution;

2. charging the suspension and sulfuric acid to a pressure vessel to provide an acidified solid-liquid suspension;

3. heating the solid-liquid suspension in the pressure vessel to a temperature between about 150 °C and 300 °C for 0.5 to 4 hours to cause the nickel, copper, cobalt and zinc to be selectively leached to form a metal rich leach solution containing these metals and a residue, with the solid-liquid suspension having a sulfuric acid content of less than 35 g/l upon completion of the leaching;

4. cooling the solid-liquid suspension and then filtering the cooled suspension;

5. washing the residue;

6. extracting copper from the filtrate of step (d) with a copper specific organic solvent extractant to form an organic phase containing the copper and an aqueous raffinate and separating the organic phase from the aqueous raffinate;

7. recovering the copper from the separated organic solvent extractant;

8. recovering the nickel, cobalt and zinc values from the separated metal rich leach solution.

Magnetic iron ore dressing process

Introduction of Malaysia Iron Ore

Iron is the world’s most commonly used metal – steel, of which iron ore is the key ingredient, represents almost 95% of all metal used per year. It is used primarily in structural engineering applications and in maritime purposes, automobiles, and general industrial applications.

Malaysia Iron-rich rocks are common worldwide, but ore-grade commercial mining operations are dominated by the countries listed in the table aside. The major constraint to economics for iron ore deposits is not necessarily the grade or size of the deposits, because it is not particularly hard to geologically prove enough tonnage of the rocks exist. The main constraint is the position of the iron ore relative to market, the cost of rail infrastructure to get it to market and the energy cost required to do so.

Malaysia Iron ore mining

Malaysia also had important mineral resources of barite, bauxite, carbonate rocks, clays, coal, copper, gold, iron ore, and silica. Iron-ore output in 2007 increased by 20 per cent to 802,030 tonnes from 667,082 tonnes in 2006. They were produced from 12 mines located in Pahang, Johore, Perak and Terengganu. Most of the iron-ore mined were of low grade from mines with small reserves. The ores were consumed mainly by the local cement, and iron and steel plants. Malaysia’s steel industry also imports iron-ore in the form of lumps and pellets for their manufacturing requirements. Most of the imported iron-ore are sourced from Brazil, Chile and Bahrain.

Malaysia Iron ore mining, Iron Ore Crushing Plant in Malaysia

Iron ore mining industry has taken an important role in Malaysia. During the iron ore processing plants, we need iron ore crusher, iron ore mill, iron ore screening equipment, iron ore conveyors etc. Other related mining in Malaysia are tin mining in Malaysia, kaolin plant in Malaysia, limestone mines in Malaysia, dolomite mining in Malaysia, mineral mining plant in Malaysia, coal mining machines in Malaysia, sand mining equipments in Malaysia, concrete construction industry etc.

Iron Ore Crushing Plant in Malaysia

Almost all of the Malaysia iron ore that is mined is used for making steel. So we need the extraction of a pure metal from its ore. The extract the metal from ores, several physical and chemical methods are used. The method used depending upon chemical properties and nature of the ore from which it is to be extracted. It involves four main steps:

1. Crushing and grinding of the ore.

2. Concentration or dressing of the ore.

3. Reduction to free metal.

4. Purification or refining of the metal.

and flexibility of a Lippmann Jaw. Its large feed opening, and force-feeding

action from the inward and downward eccentric movement of the swing jaw,

means increased capacity. Longer, curved jaw dies, a non-choking crushing

action design, and a larger eccentric throw result in a reduction in nip angle,

a more positive bite, and greater ratio of reduction.

A Lippmann Jaw can have a smaller discharge setting, allowing for a higher

degree of flexibility with related equipment. Positive setting adjustment is easy.

Reliability is the hallmark of a Lippmann Jaw, featuring rugged ribbed frame

construction, a one piece cast pitman, heavy duty rock ribs that protect

Belt conveyor abstract

Bulk material transportation requirements have continued to press the belt conveyor industry to carry higher tonnages over longer distances and more diverse routes. In order keep up, significant technology advances have been required in the field of system design, analysis and numerical simulation.

Belt Conveyor

The application of traditional components in non-traditional applications requiring horizontal curves and intermediate drives have changed and expanded belt conveyor possibilities. Examples of complex conveying applications along with the numerical tools required to insure reliability and availability will be reviewed.

Belt conveyor abstract

Although the title of this presentation indicates “new” developments in belt conveyor technology will be presented, most of the ideas and methods offered here have been around for some time. We doubt any single piece of equipment or idea presented will be “new” to many of you. What is “new” are the significant and complex systems being built with mostly mature components.

What is also “new” are the system design tools and methods used to put these components together into unique conveyance systems designed to solve ever expanding bulk material handling needs. And what is also “new” is the increasing ability to produce accurate computer simulations of system performance prior to the first system test (commissioning).

Energy Efficiency

Minimizing overall power consumption is a critical aspect of any project and belt conveyors are no different. Although belt conveyors have always been an efficient means of transporting large tonnages as compared to other transport methods, there are still various methods to reduce power requirements on overland conveyors. The main resistances of a belt conveyor are made up of:

• Idler Resistance

• Rubber indentation due to idler support

• Material/Belt flexure due to sag being idlers

• Alignment

These resistances plus miscellaneous secondary resistances and forces to over come gravity (lift) make up the required power to move the material.

As such, the main focus of this presentation will be the latest developments in complex system design essential to properly engineer and optimize today’s long distance conveyance requirements.

In a typical in-plant conveyor of 400m length, power might be broken into its components as per Figure 1 with lift making up the largest single component but all friction forces making up the majority.

In a high incline conveyor such as an underground mine slope belt, power might be broken down as per Figure 2, with lift contributing a huge majority. Since there is no way to reduce gravity forces, there are no means to significantly reduce power on high incline belts. But in a long overland conveyor, power components will look much more like Figure 3, with frictional components making up almost all the power. In this case, attention to the main resistances is essential.

The specifics of power calculation is beyond the scope of this paper but it is important to note that significant research has been done on all four areas of idlers, rubber indentation, alignment and material/belt flexure over the last few years. And although not everyone is in agreement as to how to handle each specific area, it is generally well accepted that attention to these main resistances is necessary and important to overall project economics.

Route Optimization

Horizontal Adaptability Of course the most efficient way to transport material from one point to the next is as directly as possible. But as we continue to transport longer distances by conveyor, the possibility of conveying in a straight line is less and less likely as many natural and man-made obstacles exist. The first horizontally curved conveyors were installed many years ago, but today it seems just about every overland conveyor being installed has at least one horizontal change in direction. And today’s technology allows designers to accommodate these curves relatively easily.

Conveyor Ltd of Australia, this 9 km overland carries 6000 mtph with 4×1500 kW drives installed. The Wyodak Mine, located in the Powder River Basin of Wyoming, USA, is the oldest continuously operating coal mine in the US having recorded annual production since 1923. It currently utilizes an overland (Figure 7) from the new pit to the plant 756m long (2,482 ft) with a 700m (2,300 ft) horizontal radius. This proves a conveyor does not need to be extremely long to benefit from a horizontal turn.

Another industry that would not be able to use belt conveyors without the ability to negotiate horizontal curves is construction tunneling. Tunnels are being bore around the world for infrastructure such as waste water and transportation. The most efficient method of removing tunnel muck is by connecting an advancing conveyor to the tail of the tunnel boring machine. But these tunnels are seldom if ever straight.

Jaw Crushers Features and Innovations

Coarse and initial size reduction of hard to brittle materials

Retsch jaw crushers are used for the rapid, gentle crushing and pre-crushing of medium-hard, hard, brittle and tough materials. Their variety of materials offered, such as heavy-metal free steel, efficiency and safety makes them ideal for sample preparation in laboratories and industrial plants. The throughput and grind size depend on the type of instrument, the gap width and the crushing properties of the sample. jaw crusher s are particularly suitable for the preparation of rocks, minerals, ores, glass, ceramics, construction materials, brittle metal alloys, slag, synthetic resins and many other hard, brittle substances.

Superiority in detail – technology from RETSCH

With respect to the subsequent analysis, jaw crusher s are always at the very front of the sample preparation chain. They are used for pre-crushing mainly hard and brittle materials. The fine grinding method depends on the analysis to follow and can be carried out with either

■ ball mills and mixer mills,

■ mortar grinders, or

■ disc mills and vibratory disc mills.

Many unique details show that RETSCH jaw crusher s are the ideal choice when the rapid and gentle crushing and pre-crushing of hard and brittle materials is to be accomplished.

Top performance in many areas

RETSCH jaw crusher s are primarily used in laboratories and pilot plants under industrial conditions, but can also be used on-line for the quality assurance of raw materials. The jaw crusher s are offered in four different models: BB 51, BB 100, BB 200 and BB 300. With a feed size of between 35 and 150 mm and depending on the model, the jaw crusher s can achieve a grind size of down to 0.5 mm. The main fields of applications are:

used gold washing plant for sale
Construction materials

Mineralogy and metallurgy

Ceramics and glass

Materials research

Environmental analysis

Their good grind size and their high crushing ratio demonstrate the great efficiency of RETSCH Jaw Crushers.

Versatile applications and long working life

Breaking jaws for RETSCH Jaw Crushers are available in various materials and thus allow versatile applications and a long working life.

They are available in:

■ Manganese steel

■ Stainless steel

■ Tungsten carbide

■ Zirconium oxide, partially yttrium-stabilized

■ Steel free from heavy metals

No matter whether wear-resistance or heavy-metal-free size reduction is required – for every application there are a suitable grinding tool available.

Continuous gap width adjustment and display

The gap width is set by using an analog scale. The BB 51 has a digital display with a setting and read-off accuracy of 0.1 mm. This means that reproducible crushing processes are possible, particularly since it is possible to compensate for wear.

Zero-point adjustment to compensate for wear

Depending on the material and the throughput, sooner or later the breaking jaws will start to show signs of wear. This means that the set breaking jaw distance or the crushing gap will increase with time. In order to still be able to obtain reproducible crushing results this wear must be compensated. With jaw crusher s whose gap width can only be set in fixed steps, compensation for wear is not possible. This means that reproducibility can no longer be assured. In comparison, RETSCH Jaw Crushers can be continuously adjusted and therefore breaking jaw wear can be compensated. This is done by slowly altering the gap width setting with the motor running until the breaking jaws are heard to come into contact.

The new zero point thus obtained is saved by pressing the reset key (BB 51) or readjusting the scale (BB 100 to BB 300). Increased user convenience combined with maximum working safety Safety is very important for RETSCH Jaw Crushers. The interior of the

feed hopper cannot be accessed by hands and the baffles prevent the sample material from rebounding. Integral Belleville spring washer packages and a thermal overload protection switch protect the jaw crusher s against overloading. The hopper is hinged for easy cleaning (BB 100 to BB 300) or can be easily removed. The jaw crusher s run very smoothly and quietly. Due to their solid design, RETSCH Jaw Crushers are virtually maintenance-free. RETSCH type BB 200 and BB 300 Jaw Crushers are also available in versions which can be included in process lines. Their robust design means that they are not only suitable for batch-wise operation, but they are also particularly suitable for continuous size reduction in on-line operation.

BB 200 and BB 300 as process line versions

RETSCH type BB 200 and BB 300 Jaw Crushers are also available in versions which can be included in process lines. Their robust design

means that they are not only suitable for batch-wise operation, but they are also particularly suitable for continuous size reduction

in on-line operation.

The on-line versions of the RETSCH Jaw Crushers are supplied without the feed hopper and motor protection switch. The three-phase

current version of the motor will be supplied as per customer’s specifications.

jaw crusher : the work features and machine types

Jaw crusher in mining, building materials, construction department mainly used for crushing machine and crushing machine.

Jaw Crusher

Jaw crusher work part is two jaw plate, one is fixed jaw plate (fixed jaw), vertical (or top WaiQing) fixed in the body is former wall, another is activities jaw plate (dynamic jaw), location, and fixed jaw plate tilt formed under the big crushing cavity (small chamber).Activities with the jaws of fixed jaw plate wants to do periodically reciprocating motion, sometimes separate, sometimes approaching.Apart, material into the crushing cavity, finished products; discharged from Close, make into two pieces of material between the jaw plate by extrusion, bend and fracturing effect and broken.

Jaw crusher according to activities jaw plate swinging different ways, can be divided into simple swing jaw crusher (Jane put jaw crusher ). Complex swing jaw crusher (pendulum jaw crusher ) and comprehensive swing jaw crusher 3 kinds.

Jaw crusher work principle

Dynamic jaw hanging in mind shaft, can make wag, eccentric shaft rotates, the connecting rod does vertical reciprocating motion.

Drive two thrust board also do reciprocating motion, thus pushing move around reciprocating motion, jaws do realize breakage and discharging.

This crusher adopts crank double linkage mechanism, although still suffer a lot of jaws, and the crushing counterforce partiality axis and connecting force is not big, but more than for industrial made mainframes and medium-sized machine, used in crushing hard materials.

In addition, the crusher work, move each point on the jaw trajectory is centered mandrels arc radius of arc, the distance is equal to point to axis, the top arc small, lower arc big, crushing efficiency is lower than average, the broken for 3-6. Because trajectory simple, therefore calls simple swinging jaw crusher .

Jane put jaw crusher compact structure simple, eccentric shaft transmission parts such as force small; Due to the dynamic jaw vertical displacement is lesser, processing materials is little excessive broken phenomenon, dynamic jaw jaw plate wear small.

Pendulum jaw crusher work principle

Dynamic jaw hanging in eccentric shaft directly at the top, as the crank rod system by eccentric shaft rods, the eccentric drive directly, the lower hinge connecting dynamic jaw thrust board support to wall frame.When eccentric shaft rotates, the dynamic jaw trajectory of each point on the circumference by hanging point line (radius equal eccentricity), gradual downward into the oval, the more the slant to bottom, oval, until the lower and thrust plate junction arc trajectory.Because the machinery of different points on dynamic jaw trajectory of more complex, so called complex swing jaw crusher .

After tilting jaw crusher compared with Jane tilting, its advantage is: quality is lighter, less, more compact structure component, broken lumen filled with degree is good, with materials by uniform broken, to block bottom mandatory move jaw is unloading, launch finished higher, than with specifications productivity of Jane put jaw crusher 20-30% higher than the productivity;Material blocks in the lower have bigger jaws move up and down movement, a cube tumbling to the shape of, reducing the discharged as Jane tilting products that flake composition, product quality is better.

Jaw crusher work principle:

Jaw crusher has a variety of structure, work principle is the same, namely through periodic motion to move hubei. Moving in hubei crushing material around the suspension swinging heart axial fixation in the process of hubei, located between the two materials and hubei board by crush, fracturing and bending comprehensive effect. In the beginning, the pressure is lesser, make the material smaller, material of between toward each other, squeezed tightly; When pressure rise to more than material can withstand strength, namely happen. Conversely, when moving broken hubei to the opposite direction from fixed hubei, swing by material is self-possessed downward motion.

Move each of hubei periodically to make materials movement by a crush role, and to discharge send a distance. After several cycles, being broken after the material comes from discharging mouth eduction. As motor turns continuously turned and broken motor jaw make periodic motion crush and discharge material, realize batch production.

Iron ore production plant to serve steel manufacturers

iron ore sales for the year reached a new record level of 9,8 million tons (2009: 7,4 million tons), due mainly to the continued demand from China and a strong recovery in the Japanese and South Korean steel industry. European and South African steel capacity utilisation has not completely recovered to the 2008 highs and these markets could remain subdued in the short term. Despite the global market uncertainty, the market fundamentals for seaborne iron ore trade remain strong and spot prices have recovered well over the past year.

The past financial year finally saw the demise of the annual “benchmark price”, with a strong move towards spot pricing, although pricing mechanisms continue to evolve. Currently, Assmang’s prices are negotiated quarterly. However, other producers are using different periods, spot prices and a blend of fixed and index pricing. The new pricing mechanism follows the supply-and-demand dynamics of iron ore more accurately and to some extent mitigates the high volatility experienced previously. However, steelmakers are wary of the uncertainty that this has caused in their raw material costs as many of their customers are accustomed to annual contracts, and are considering the use of other mechanisms in order to obtain pricing stability.

Post the end of the industry’s fiscal year (31 March), when annual prices were still in place, prices for the first quarter, effective from 1 April 2010, increased substantially, with increases in excess of 95% for both lumpy and fine grades. Prices for the new financial year could remain at high levels, subject to Chinese steel production being maintained and the continued recovery of the developed economies.

Sales volume for next year is expected to increase modestly in line with a better utilisation rate on the iron ore rail line between the mine and the Saldanha Bay port. Efficient utilisation of the rail capacity for the transportation of iron ore to the port remains the immediate challenge in the short term.

Despite the prices increasing significantly in the last financial quarter, the increased sales volumes did not compensate fully for lower average prices for the financial year, and the contribution to Assore’s headline earnings by Assmang’s Iron Ore Division amounted to R718 million (2009: R1 080 million).

Capital expenditure for the year in the Iron Ore Division was R2,3 billion (2009: R2,2 billion) of which R2,1 billion was spent on infrastructural items for the expansion project at the Khumani Iron Ore Mine. This project will increase the mine’s sales capacity from 10 million tons to approximately 16 million tons of iron ore per annum, and is expected to be completed by the scheduled date of July 2012 and within budget.

Iron Ore Production Cost Reports & Databases

iron ore production in the Pilbara

Activities involved in finding, mining and processing iron ore at our Pilbara operations have been simplified in the following diagram. Rio Tinto operates 11 iron ore mines in the Pilbara and the specific sequence of activities varies from mine to mine. Excellence in planning, scheduling and quality control are fundamental to the process.

Resource development

1. Exploration and evaluation

The team identifies and quantifies ore bodies, by using a range of geological, geophysical and metallurgical techniques. In its simplest form exploration involves drilling in remote areas to sample areas.

2. Metallurgical assessment

The data from exploration activities is logged, mapped, analysed and interpreted through models.

3. Mine planning and scheduling

The team develops a detailed plan of which ore bodies to mine in what sequence, to deliver the required product quality at an  appropriate cost. The process of mine planning commences many years before a mine is developed, and continues on a day-to-day basis once the mine is operational.

Iron ore Mine operations

Drill and Blast

Areas for open-pit mining are selected using the mine plan. Identified areas are tagged, and then holes are drilled in an appropriate pattern by rigs. The drill holes are filled with an explosive, most often ANFO (Ammonium Nitrate/Fuel Oil) and then charged. The resulting blast breaks the material to a size required for digging.

Load and Haul

The broken material is loaded for transport by face shovels, excavators or front-end loaders into haul trucks. Haul trucks at our operations are typically in the 190 tonne and 240 tonne class. Overland conveyors are used to transport partially crushed feed at sites

where there are long distances between the pits and process plants.

Process

Processing of the ore ranges from simple crushing and screening to a standard size, through to processes that beneficiate or upgrade the quality of the iron ore products. This is done by physical processes, which remove impurities by differences in particle density or size gravity or size separation. Processing may be wet or dry.

Stockpile and rail-load out

The processed ore is stockpiled and blended to meet product quality requirements, before being reclaimed and conveyed to rail load-out. The ore is loaded into ore cars for transport to the port facilities.

Rail and port operations

Rail

Ore is railed up to 460 kilometres to the coast along a dedicated privately owned rail system. A typical train consist comprises 2 GE Dash 9 locomotives, 230 ore cars and is over 2.4 kilometres long. A single driver, supported by centralised track control, operates the train.

Ore car dumping

Once the train arrives at the port the ore cars go through the car-dumper. The ore cars are rotated and the ore flows out into bins and then is discharged onto conveyors.

Stockpile

The ore is stockpiled according to product type and the quality control plan. The travelling stackers create 250m long stockpiles. Rotary bucket-wheel reclaimers later reclaim the ore, which will be conveyed to the ship loader.

Ship-loading

Vessels are loaded at the berths alongside the ore wharf. Lump ore is rescreened to remove undersize material. Reclaimed ore is conveyed along the wharf and the ore is loaded into the vessel’s holds by travelling, slewing and luffing shiploaders.

IRON ORE MINES

iron ore MINES

Locality – The Iron Ore Division is made up of the Beeshoek Mine located on the farms Beeshoek (448) and Olynfontein (475) and the Khumani Mine situated on the farms Bruce (544), King (561), and Mokaning (560). All properties are in the Northern Cape approximately 200 kilometres west of Kimberley. The Beeshoek open-pit operations are situated 7 kilometres west of Postmasburg and the new Khumani open pits are adjacent to, and south-east of, the Sishen Mine, which is operated by Kumba Resources.

Located at latitude 28°30’00″S/longitude 23°01’00″E, and latitude 27°45’00″S/longitude 23°00’00”E respectively. Khumani Mine supplies iron ore to the export markets. Exports are railed to the iron ore terminal at Saldanha Bay. Beeshoek Mine ore is supplied to local customers.

Iron Ore Mines History

mining of iron ore (mainly specularite) was undertaken as early as 40 000 BC on the farm Doornfontein which is due north of Beeshoek. The potential of iron ore in this region was discovered in 1909, but, due to lack of demand and limited infrastructure, this commodity was given little attention. In 1929, the railway line was extended from Koopmansfontein (near Kimberley) to service a manganese mine

at Beeshoek. In 1935, The Associated Manganese Mines of South Africa Limited (Assmang) was formed, and in 1964 the Beeshoek Iron Ore Mine was established, with a basic hand-sorting operation. In 1975, a full washing and screening plant was installed and production increased to 7 million tons per annum. The Khumani Iron Ore Mine was commissioned in 2007 and is ramping up to approximately 10 million tons per annum, with expansion plans to 16 million tons per annum being investigated.

Mining authorisation – The Beeshoek mining lease (ML3/93) comprises an area of 5 686 hectares and is located on the farms Beeshoek (448) and Olynfontein (475). An application for the conversion to a new-order mining right was submitted during

the 2009 financial year.

The Khumani mining right comprises an area of 7 388 hectares and is located on the farms Bruce (544), King (561) and Mokaning (560). The mining right was granted during the 2007 financial year.

Geology – The iron ore deposits are contained within a sequence of early Proterozoic sediments of the Transvaal Supergroup deposited between 2 500 and 2 200 million years ago. In general, two ore types are present, namely laminated hematite ore forming part of the Manganore Iron Formation and conglomerate ore belonging to the Doornfontein Conglomerate Member at the base of the Gamagara Formation. The older laminated ore types occur in the upper portion of the Manganore Iron Formation as enriched high-grade hematite bodies. The boundaries of high-grade hematite orebodies crosscut primary sedimentary bedding, indicating that secondary hematitisation of the iron formation took place. In all of these, some of the stratigraphic and sedimentological features of the original iron formation are preserved.

The conglomeratic ore is found in the Doornfontein Conglomerate Member of the Gamagara Formation and is lenticular and not

persistently developed along strike. It consists of stacked, upward fining conglomerate-gritstoneshale sedimentary cycles. The lowest conglomerates and gritstones tend to be rich in subrounded to rounded hematite ore pebbles and granules and form the main orebodies. The amount of iron ore pebbles decreases upwards in the sequence so that upper conglomerates normally consist of poorly

sorted, angular to rounded chert and banded iron formation pebbles.

The erosion of the northern Khumani deposit is less than that in the southern Beeshoek area. The result is that Khumani is characterised by larger stratiform bodies and prominent hangingwall outcrops. The down-dip portions are well preserved and

developed, but in outcrop the deposits are thin and isolated. Numerous deeper extensions occur into the basins due to karst development. A prominent north-south strike of the ore is visible. The southern Beeshoek orebodies were exposed to more erosion

and are more localised and smaller. Outcrops are limited to the higher topography on the eastern side of the properties. Down-dip to the west, the ore is thin and deep. The strike of the orebodies is also in a north-south direction, but less continuous.

Iron ore beneficiation technology

1. Magnetite beneficiation of low grade

Mainly used for sorting the “Anshan type” magnetite. Since strong magnetic minerals, a good grinding good selection of domestic magnetic separation plant are used stage grinding and multi-stage grinding process, the coarse-grained disseminated magnetite by the former (a grinding), fine-grained, micro-fine disseminated magnetite with the latter (Sec or three grinding). Developed our own series of permanent magnet, thus enabling realization of a permanent magnet of the magnetic separator. 70 years later, the magnetite concentrator in the country to promote a fine sieve and then grinding the new technology, the concentrate grade from 62% to 66%, to achieve the Ministry of Metallurgical Industry 65% u200bu200bconcentrate grade requirements.

2. Weakly magnetic iron ore

80 years later, magnetic beneficiation technology for roasting, wet high intensity magnetic separation, flotation and re-election of the weak magnetism and other processes, equipment and new varieties of pharmaceutical research continue to improve , so concentrate grade, metal recovery continues to increase. Such as the Anshan Iron and Steel Qidashan Concentrator with weak magnetic – magnetic – the new flotation process (Figure 3.2.24), obtained encouraging achievements.

3. Polymetallic total (with) ORE

Mineral composition of such complex, diverse, so the method used, equipment and processes are different, such as the Bayan Obo iron ore by reverse flotation – more gradient magnetic separation, flocculation and flotation, weak magnetic – reverse flotation – intensity magnetic separation, weak magnetic – are flotation, magnetic separation, such as different roasting process, in order to improve the recovery rate of iron and comprehensive recovery of rare earth oxides. Panzhihua Iron TFe53% by magnetic separation to obtain about vanadium iron ore, magnetic separation tailings after the election by weak magnetic sweep – intensity magnetic separation – gravity – flotation – dry electrostatic separation, titanium ore and sulfur to obtain fine cobalt ore, recovery of titanium and cobalt. Daye Iron Mine by weak magnetic – magnetic and flotation, comprehensive recovery of iron, copper and cobalt, sulfur and other elements.
