Chromium Ore - an overview ScienceDirect Topics

Chromium Ore. Chromium ores are often classified based on their elemental composition and industrial use into: high-chromium (46–55% Cr2O3, Cr:Fe >2.1) used for metallurgical processes, high-iron (40–46% Cr2O3, Cr:Fe 1.5–2.1) used for chemical and metallurgical purposes, and high-aluminum (33–38% Cr2O3, 22–34% Al2O3) used widely as refractory material [1].

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.
