Beneficiation may involve physical or chemical processes. Often, as in the case of panning for gold, the desired ore or metal is denser than the gangue. The latter can be suspended in a stream of water and flushed away. The iron ore magnetite, Fe 3 O 4, is ferrimagnetic. It can be separated from abundant deposits of taconite by grinding to a ...

The Kemi chromium mine is an open-pit mine with a waste rock to ore ratio of 5.5:1. At Kemi, the ore from the mine contains 11% iron and 25.5% Cr 2 O 3. After beneficiation, the concentrate contains between 35% Cr 2 O 3 in the coarse fraction (lumps) and 44% of Cr 2 O 3 in the fines. The process steps will be explained in the …

Conventional methods of beneficiation such as gravity concentration, magnetic separation, and flotation cannot effectively increase the Cr/Fe ratio in chromite ore unless the Fe occurs in the gangue materials (Murthy et al., 2011, Nafziger, 1982) since the Fe content mainly depends on the spinel composition.
