Review of Chromite Ore Processing Residue (COPR) Past

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.
