「chromite mineral processing technique」
Chromium processing Britannica. Chromite deposits are mined by both underground and surface techniques. Much of the ore is rich enough to be used directly: for production of ferrochromium, a rich, lumpy ore containing more than 46 percent Cr 2 O 3 and having a chromiumiron ratio greater than 2:1 is preferred, but ores with a lower ratio and as little as 40 percent Cr 2 O 3

A process for direct stainless steel production from nickel laterite
CONCLUSIONS In this paper we have discussed the integrated production process of stain- less steel from the Fe-Ni and Ch-Cr melts using the iron-rich nickel ore and chromium-poor chromite ore. Notable features are as follows: (1) effective utilization of Fe, Ni and Cr of 221 the iron-rich nickel ore; (2) effective utilization of the chromium

Potential Toxic Effects of Chromium, Chromite Mining and Ferrochrome
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. !

SOME ASPECTS OF THE PRODUCTION OF FERROCHROME ALLOYS
The chromite ore Cr/Fe ratio is of importance as it directly affects the alloy Cr grade whilst the gangue elements affect the melting energy and rate as well as the slag chemistry. The chromite spinel ore morphology can be described stoichiometrically as (Fe, Mg)(Cr,Al,Fe)2O4 and chromite ores often contain gangue elements of SiO2 and MgO.
