Abstract Chromite ore processing residue COPR derived from the so called high lime processing of chromite ore contains high levels of Cr III and Cr VI and has a pH between 11 and 12 Ferrous sulfate which is used for remediation of Cr VI contamination in 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 sit For instance New Jersey alone has over 2 million tons of waste COPR
