Extraction of Cr(VI) from chromite ore processing residue

2020/7/1Hence, the development of an effective Cr(VI) extraction method, which can achieve both COPR detoxification and chromium recovery, is of great significance for COPR treatment. Recently, several feasible methods for extracting Cr(VI) from COPR have been reported, such as acid leaching [ 10, 11 ], salt solution leaching [ 12 ] and roasting-leaching [ 13, 14 ].

Under these conditions, the iron oxides present in the ore body are reduced to metallic iron and the resulting separation of chromium occurs by forming sodium chromite (NaCrO 2). The reduced samples are magnetically separated for the recovery of an iron-rich fraction, and a non-magnetic fraction containing NaCrO 2, MgO and other impurities.
