Significant research effort has been focused on recovery of chromite values from the plant tailings which need to be focused on mineral conservation, utilisation and environment protection point of view 9.
Chromium processing, preparation of the ore for use in various products. Chromium Cr is a brilliant, hard, refractory metal that melts at 1,857 176C 3,375 176F and boils at 2,672 176C 4,842 176F. In the pure state it is resistant to ordinary corrosion, resulting in its application as an electroplated

Chromite ore processing residue COPR is a waste byproduct of chromate production that contains high levels of hexavalent chromium CrVI. Although the high temperature chromite process was banned in several countries, its legacy still exists at numerous contaminated sites.
of metallic chromium, it is used as a special steel and ferrochrome alloying ingredient in stainless steels Rama Murthy et al, 2011. Minimum 10.5 chromium is regarded for stainless steel. Chromium Cr does not occur in nature, it is present in chromite ores as an iron chromium oxide FeCr2O4 Gundewar et al, 2013.
Chromium Cr is a hard, bluish metallic element. The only ore of chromium is the mineral chromite and 99 percent of the world’s chromite is found in southern Africa and Zimbabwe. Geologists estimate that there are about 11 billion tons of mineable chromite ore in the world, enough to supply the current demand for hundreds of years.
tion of chromite and gangue minerals, however, necessitated fine grinding and limited the amount of chromite recoverable. Recovery of chromium in concentrate that assayed 48 percent chromic oxide or higher ranged from approximately 20 percent for lowgrade ores 10 to 12 percent Cr203 to more than 95 percent for 1 highgrade sample 42 percent ...
Chromite, the only ore of chromium, was first discovered in the United States sometime about 1808 on the farm of Isaac Tyson, Jr., just north of Baltimore, Md. Scattered deposits of chromium minerals in an area of northeastern Maryland and southeastern Pennsylvania were the source of nearly all of the chromium products in the world between 1828 ...
