Chromite | Chromium Ore, Properties, Uses and Occurrence
The only ore of chromium. Chromium is used with various other metals to give hardness to steel, also as a plating material because of its noncorrosive nature. Chromite bricks are used to a considerable extent as linings for metallurgical furnaces, because of their neutral and refractory character. The bricks are usually made of crude chromite and coal tar but sometimes of chromite with kaolin ...
Conversion of Chromium Ore Processing Residue to Chrome Steel
Trivalent chromium in chromite ore was oxidized to hexavalent chromium. The highly soluble hexavalent chromium was then removed from the COPR (left over Chromium Ore Processing Residue) leaving unoxidized trivalent chromium and slowdissolving hexavalent chromium compounds [Burke et al., 1991]. In the absence of information on the toxicity of hexavalent chromium, COPR was .

Ferrochrome
Average chrome content in stainless steel is approx. 18%. It is also used to add chromium to carbon steel. FeCr from South Africa, known as "charge chrome" and produced from a Cr containing ore with a low carbon content, is most commonly used in stainless steel production. Alternatively, high carbon FeCr produced from highgrade ore found in Kazakhstan (among other places) is more commonly ...
