Beneficiation of Low Grade Chromite Ores from Sukinda
of the chromite ore beneficiation plants in Sukinda region treat selected rich ores with rejection of huge quantities of low and sub-grade ore (10-38% Cr203). Beneficiation is mostly limited to crushing, grinding, desliming and hydrosizing to produce a concentrate of about 50% Cr203 with a yield of about 25-35%.

Chromite: The only mineral ore of chromium metal
Chromite is an oxide mineral composed of chromium, iron, and oxygen (FeCr 2 O 4 ). It is dark gray to black in color with a metallic to submetallic luster and a high specific gravity. It occurs in basic and ultrabasic igneous rocks and in the metamorphic and sedimentary rocks that are produced when chromite-bearing rocks are altered by heat or ...

Potential Toxic Effects of Chromium, Chromite Mining …
Chromite ore is mined, crushed and processed to produce chromite concentrate. To create ferrochrome, chromite concentrate is combined with a reductant (coke, coal, charcoal or quartzite) in a high temperature submerged arc furnace or direct current arc furnace. See Appendix 1 for resources about ferrochrome production processes. !
