Chromite ore processing residue (COPR) is a waste byproduct of chromate production that contains high levels of hexavalent chromium (Cr[VI]). Although the high temperature chromite process was banned in several countries, its legacy still exists at numerous contaminated sites. For instance, New Jersey alone has over 2 million tons of waste COPR.

When chromite, the mineral, is extracted from the earth's mantle, it is referred to as chrome ore. Chrome ore is crushed, screened, jigged into chrome concentrate and then smelted into ferrochrome. Ferrochrome, with nickel, is then processed into stainless steel. The processing of chromite is depicted in Figure 1. As chrome ore,

Get Priceof chromite in UG2 concentrate is, however, a major disadvantage due to the problems associated with smelting such a concentrate in conventional submerged arc furnaces. In addition to increasing the specification on the minimum PGM grade of concentrates, smelters have had to impose strict specifications on the levels of chromite in the concentrate.
