COPR is produced during the process of extracting chromium (, chromite (C^Oa)) from its ore. The extraction process involves roasting the chromite ore to oxidize the chromium therein from the trivalent to the hexavalent state, then treating the oxidized chromium with soda ash (, Na 2 CO 3) to form sodium chromate (Na 2 CrO 4). The principal reaction may be described as follows:
