Iron Ore - Deposits, Reserve, Demand & Mining

1. Magnetite beneficiation of low grade

Primarily used for sorting the "Anshan type" magnetite. Since strong magnetic minerals, a great grinding superior choice of domestic magnetic separation plant are employed stage grinding and multi-stage grinding method, the coarse-grained disseminated magnetite by the former (a grinding), fine-grained, micro-fine disseminated magnetite using the latter (Sec or 3 grinding). Created our own series of permanent magnet, thus enabling realization of a permanent magnet from the magnetic separator. 70 years later, the magnetite concentrator inside the country to promote a fine sieve after which grinding the new technologies, the concentrate grade from 62% to 66%, to achieve the Ministry of Metallurgical Market 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 in the weak magnetism along with other processes, equipment and new varieties of pharmaceutical analysis continue to improve , so concentrate grade, metal recovery continues to boost. For instance the Anshan Iron and Steel Qidashan Concentrator with weak magnetic - magnetic - the new flotation method (Figure three.two.24), obtained encouraging achievements.

3. Polymetallic total (with) ORE

Mineral composition of such complicated, diverse, so the approach employed, equipment and processes are distinct, including the Bayan Obo iron ore by reverse flotation - extra gradient magnetic separation, flocculation and flotation, weak magnetic - reverse flotation - intensity magnetic separation, weak magnetic - are flotation, magnetic separation, like unique roasting approach, to be able to boost 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 just after the election by weak magnetic sweep - intensity magnetic separation - gravity - flotation - dry electrostatic separation, titanium ore and sulfur to acquire 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 along with other components.
