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.
Magnetic material remains as a concentrate and is transferred to the primary grinding plant. The primary grinding plant of four ball mills grinds the ore in slurry into fine particle sizes of <50 µm before further magnetic separation to produce a concentrated magnetite ore stream, with elevated Iron (Fe) grades of ~58%.
Magnetic separation is the most commonly used beneficiation method for ferrous metal ore such as iron ore. It is divided into weak magnetic separation and strong magnetic separation according to the different magnetic field strengths. ... which overcomes the resultant force of all mechanical forces opposite to the direction of the magnetic ...
1. The dump truck feeds the raw ore into the hopper and the vibrating feeder. The vibrating feeder feeds evenly to the jaw crusher, which crushes large rocks to less than 200mm.. 2.
