A study of reduction and magnetic separation of iron
Abstract The removal of iron as magnetite from a high iron bauxite ore was investigated by carbothermal reduction and magnetic separation Thermodynamic calculations using HSC Chemistry 61 were utilised to determine the equilibrium compositions of the reaction products as a function of temperature and carbon additions Gravity separation process and strong magnetic separation process are mainly used to separate coarsegrained (2mm20mm) and mediumgrained weakly magnetic iron ore Among them, coarse and extremely coarse (greater than 20mm) ores are commonly used in heavy medium or jigging gravity separation technology ;Separation process of iron ore,iron ore magnetic The ore is mainly composed of magnetite, hematite, martite, and quartz It is very difficult to produce a highquality iron ore concentrate by magnetic separation alone for this type of iron ore The ore is first ground using ball mills down to about 90% 75 μmDevelopments in the physical separation of iron ore
