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.

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.
