Beneficiation is the process where ore is reduced in size and gange separated from the ore. Since all iron ore deposits have unique mineralogy, the beneficiation process is specific to each deposit. Separation of certain minerals can be efficiently achieved by taking advantage of the physical, electrical and magnetic properties.

1. Introduction. The processing and utilization of iron ores are intimately linked to their mineralogical characteristics, liberation pattern, and the nature of inclusion of the impurities such as SiO 2, Al 2 O 3, P and goethitic, oolitic and wad type ores containing high silica and alumina are very difficult to process by conventional beneficiation techniques.

The iron (Fe) content of such ores ranges from 72% to 35%. The highly friable and fully liberated constituents in ore, such as alumina and silica, generate a large quantity of fines during mechanized mining and crushing. Fine gangue material or iron ore slimes having <45%55% Fe are discarded as reject during the ore beneficiation process.
