Beneficiation of minerals is separation of ore from waste based on physical properties like gravity, magnetism etc. It needs several requirements to achieve its full potential, the primary of which is the grain size, as we can't test gravity between a boulder and a gravel. The run-of-mine ore consists of sizes ranging from 2–3m...

BENEFICIATION

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.
