REPORT ON ENVIRONMENTAL ISSUES OF CHROMITE MINING

Many mines have chrome ore beneficiation (COB) plants, where chromium content in the ore is concentrated through washing and sorting. Washings from the COB plants can also be a source of Cr(VI). Overburden generation: Opencast chromite mining generate enormous quantities of overburden (OB). The stripping ratio varies from 1:5 to 1:10.

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].
