Second Iron Ore Magnetic Separation Process

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

C. Crisafio, in Iron Ore, 2015. 10.4.2.3 Use with WHIMS. Iron ore processors may also employ magnetic separation for beneficiation of classifier output streams. Wet high-intensity magnetic separators (WHIMS) may be used to extract high-grade fine particles from gangue, due to the greater attraction of the former to the applied magnetic field

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

Jun 20, 2018 The aim of the roasting process is the transformation of the nonmagnetic iron phases found in BR (namely hematite and goethite), to magnetic ones such as magnetite, w stite, and metallic iron. The magnetic iron phases in the roasting residue can be fractionated in a second stage through wet magnetic separation, forming a valuable iron

Sep 25, 2018 In some places reduction roasting of the low grade hematite ore is done to convert it into magnetic ore before the application of the magnetic separation method for the ore beneficiation. Another method which can be employed is the use of a dense medium in a gas-solid fluidized bed for the enrichment of iron ore
