Leaching of hexavalent chromium from young chromite ore

2020-3-18  Chromite ore processing residue contains unreacted chromite ore as well as residual (i.e., nonextracted) CrO 4 2−. In general, COPR is strongly alkaline, with pH values typically between 11.0 and 12.5 (Chrysochoou, Fakra, Marcus, Moon, & Dermatas, 2009; Deakin, West, Stewart, & Yardley, 2001b; Földi, Dohrmann, Matern, & Mansfeldt, 2013).

One of the recommended briquetting methods is as follows (although it should be remembered that no defined remedy recipe exists for briquetting all types of chromite ores). The ore of the 6 to 10-mm fraction is dried and mixed with hydrated lime to which mixture molasses is added at 35° to 40°C. The formed briquettes are 2 to 5 inches long, 1 to 2 inches thick, and 1.5 to 2.5 inches wide, and they are stored in

Remediation of chromite ore processing residue using

Batch tests were conducted to assess the potential use of ferrous sulfate and calcium polysulfide for the remediation of chromite ore processing residue (COPR). The remediation process entails addition of ferrous sulfate or calcium polysulfide to chemically reduce hexavalent chromium [Cr(VI)] to trivalent chromium [Cr(III)] in slurry form and pH adjustment to precipitate Cr(III) as chromium hydroxide.
