Iron ore beneficiation facilities in the country are highly inadequate i.e., only 52 concentrators cater to the need for iron ore production of about 220 MTPA(mines-316).
Wet High Intensity Magnetic Separators (WHIMS) from Multotec apply magnetism, matrix rotation and gravity to achieve para-magnetic materials separation. Applications include heavy minerals, ilmenite, manganese and iron ore (haematite) beneficiation; PGM upgrading as well as manganese recovery from slimes dams.

Beneficiation of Iron Ore. The purpose of beneficiation is to provide the following advantages: less amount of added elements in the ore; Increase the reduce ability of the ore; make the ore suitable for transport; The only processing steps used for ores mined from rich deposits (rich ores) are crushing and screening.
