Dissolution and reduction of chromite ore in

20181226&ensp·&enspchromite ore was fed into the molten slag, and was followed by reduction of iron and chromium oxides. Due to the fact that the chromite ore was fed in granular form, as expected, a greater contact area was created which influenced the dissolution / reduction reaction between the ore and the slag. The slag composition played a significant role

Review of Chromite Ore Processing Residue (COPR):

202061&ensp·&enspChromite 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.
