A discussion of magnetic separation techniques for …
Typical chromite process flowsheet In some cases, chromite concentrates can be produced by wet gravity concentration alone. In other chromite beneficiation processes, magnetic separation by RED is an essential polishing step. Figure 3 shows a typical flowsheet for upgrading chromite where gravity concentration is followed by dry …

Chrome Mining in South Africa
Early mining of chromite was on a small-scale and was relatively straightforward from outcrops or to shallow depths followed by hand sorting. However, with the increased demand, conventional open-pit mining and mechanical underground mining became necessary. There was sufficient high-grade metallurgical ore to meet demand but with …

mines are already exploiting other chromite layers within the Middle group, and these are the MG2, 3 and 4 [6]. This might be due to depreciation of high-grade chromite seams. Chromite processing involves crushing, milling to less than 1mm and further beneficiation using gravity circuits and spiral concentrators are widely used for this purpose.

Chromite | Mineralogy4Kids
The only ore of chromium, chromite is a major constituent in stainless steel. It is one of the first minerals to separate from a cooling magma, and large chromite deposits are thought to have been derived by such magmatic differentiation. Mineral Photos courtesy of R.Weller/Cochise College. Formula: FeCr 2 O 4. Year Discovered: 1845.

21.7A: Chromium Metal
Chromite ((ce{FeCr2O4})) is the most commercially useful ore, and is extensively used for extraction of chromium. Chromium is produced in two forms: Ferrochrome by the reduction of chromite with coke in an electric arc furnace. A low-carbon ferrochrome can be produced by using ferrosilicon instead of coke as the reductant.
