Magnetic separation is most used to separate natural magnetic iron ore (magnetite) from a variety of less magnetic or nonmagnetic material [7]. Magnetizing reduction is one of the most effective unit operations in the treatment of low-grade iron ores specially those which are poorly responsive to conventional beneficiation techniques such as
Get Pricemethod for the treatment of complex iron ore and low-grade iron ore resources [19,20]. Chu et al. [21] used the coal-based direct reduction and magnetic separation process to
of magnetite ores using low-intensity magnetic separation. Although magnetite stoichiometrically contains the highest iron (72.4 wt %) compared with all the other sources of iron, its low-grade ore state usually contains low iron—magnetite ores located in Australia usually contain iron grades between 14 and 45 wt % [4–6]

The typical magnetite iron ore concentrate has less than 0.1% phosphorus, 3-7% silica and less than 3% aluminium. The grain size of the magnetite and its degree of comingling with the silica groundmass determine the grind size to which the rock must be comminuted to enable efficient magnetic separation to provide a high purity magnetite

The finest of the three types of iron ore (smaller than 0.15 mm), obtained after the flotation and magnetic separation process. It can be mixed with the sinter feed or used directly in the sintering process or it can also be used to feed the pelletizing process that converts the iron ore fines into the pellets that will be used in the steel plants
Recycling one tonne of steel saves 1100 kg of iron ore, 630 kg of coal and 55 kg of limestone. Recycling one tonne of steel saves 642 kWh of energy, 1.8 barrels (287 litres) of oil and 2.3 cubic metres of landfill space. Every tonne of steel made from recycled scrap saves enough energy to power four homes for a whole year

Abstract: The effect of CaCO 3, Na 2 CO 3, and CaF 2 on the reduction roasting and magnetic separation of high-phosphorus iron ore containing phosphorus in the form of Fe 3 PO 7 and apatite was investigated. The results revealed that Na 2 CO 3 had the most significant effect on iron recovery and dephosphorization, followed by CaCO 3, the effect of CaF 2 was negligible
Steel slag can also be produced by smelting iron ore in a basic oxygen furnace. According to methods for cooling molten steel slag, steel slag is classified into five types: natural air-cooling steel slag, water-spray steel slag, water-quenching steel slag, air-quenching steel slag, and shallow box chilling steel slag [47,48]
