The iron content of the ore needs to be increased and gangue, which is native rock and minerals of lesser value within the ore itself, must be separated out. Methods such as screening, crushing, and grinding of iron ore are often used in various ways to purify.

Optimisation Of Grinding Process In A Magnetite Ore

Iron ore is beneficiated using separation steps based on mineral composition without the use of separation steps based entirely on size. In a preferred sequence of steps the iron ore is passed from a ball mill through a magnetic separator where low iron content tailings are rejected and the concentrate passed to a flotation step, where a high iron content concentrate froth is made.Economy. India has huge reserves of quality iron ore which can fulfil the growing demand for domestic iron and steel industry as well as sustain large external trade. The most important iron ore types found in India are hematite and magnetite. Nearly 61 of hematite ore deposits are found in the eastern part of India and 82 of magnetite ore.
