quantities of chromite with typically a chrometoiron (Cr/Fe) ratio of UG2 ores can contain between 10 and 25% Cr2O3 depending upon the reef width and the selected mining method. It is relatively cheap and easy to extract a portion of the chromite from a platinum concentrator tailings stream at a grade of between 40–42% Cr2O3.

Nov 27, 2017· It is the differences between Chrome vs Stainless Steel. Chromium is mined as chromite ore (FeCr2O4). Chromium ore mining, among others, is in South Africa, Zimbabwe, Finland, India, and the Philippines. The main use of chromium is as a metal alloy as in stainless steel, chrome plating, and metal ceramics. Chrome plating was once used to ...
Since exploitation of the UG2 ore would have more than doubled resources, the incentive for development of a suitable process was high. In addition, the higher rhodium content of the UG2 ore, the production of chromite as apotentially valuable byproduct, the higher PGE+Au content at some localities, and the fact that it could be

Chromite definition, a salt of chromium in the bivalent state. See more.
Chromite ore can be mined to produce chromite concentrate. It can also be crushed and processed. Chromite concentrate, when combined with a reductant such as coal or coke and a high temperature furnace can produce ferrochrome. Ferrochrome is a type of ferroalloy that is an alloy in between chromium and iron.
