Second Iron Ore Magnetic Separation Process

Magnetic elutriation improves the quality of low-grade domestic iron ore by using an alternating-current, pulsed-magnetic field to clean iron ore into a highly refined product. This innovative process differs from conventional drum type magnetic separation systems by using permanent magnets that cause magnetic entrapment

    Thus, it was confirmed that the optimum magnetic intensity to obtain ilmenite concentrate with excellent titanium content was 0.3 T in the multi-step magnetic separation process of this study. As a second step, magnetic separation was performed at a medium-intensity of 0.3 T on the Product 2 and Product 4 generated by each process step

    Jan 16, 2017 The main commercial objects of magnetic separation are, first, the diminution of the amount of earthy gangue, with a consequent increase of the percentage of metallic iron in the product, and, second, the incidental elimination of phosphorus (usually present in apatite), and often of sulphur or titanium. A crude ore, carrying about 30 per cent

    This work presents a semi-smelting reduction and magnetic separation process for the recovery of iron and alumina slag from iron rich bauxite ore. The effect of the process parameters on the recovery rate of iron, maximum particle size of the iron nugget, and the Al2O3 content of the alumina slag was investigated and optimized. The results show that the iron nuggets and alumina slag can be
