Chromium processing Britannica

Chromium processing, preparation of the ore for use in various products. Chromium (Cr) is a brilliant, hard, refractory metal that melts at 1,857 °C (3,375 °F) and boils at 2,672 °C (4,842 °F). In the pure state it is resistant to ordinary corrosion, resulting in its application as an electroplated

SOME ASPECTS OF THE PRODUCTION OF FERROCHROME

In the conventional production of stainless steels, chromium is generally introduced to the process in the form of Cr-Fe-C-Si alloys, principally as high-carbon ferrochrome or charge chrome. The level of carbon and silicon in the above alloys is important especially when refining is carried out by blowing oxygen in the melt.
