The low chromium-to-iron ratio of chromite ores is an important issue in some chromite deposits. The value of the chromite ore is indeed dictated in the market by its iron, as well as its chromium content. In the present study, a chromite concentrate was reprocessed by gravity spiral concentrator and magnetic separation to enhance the chromium-to-iron ratio.

Chromite ore processing residue COPR is a waste derived from the chromate extraction from roasted ores and is deposited in some countries in landfills. The objective of this study was to investigate the leaching characteristics of hexavalent Cr CrVI from two COPR samples obtained from unlined landfills in the Kanpur area of northern India.
