· Process optimization of a chrome ore gravity concentration Chromite deposits occur in the form of discontinuous bands, lenses, and pockets in different host rock associations. Chrome ore beneficiation Most of the chrome ores around the world are beneficiated by gravity concentration techniques.
Chromite ore processing residue (COPR) contains very high levels of chromium as Cr(III) and Cr(VI) and has a pH of ∼ to 12. Millions of tonnes of COPR have in the past been deposited in urban areas. We have studied the factors that control leaching of Cr(VI), Ca, Al, Si, and Mg from COPR by means of batch experiments, mineralogical characterization of COPR via X-ray …
Deposits Chromite deposits are the end product of the separation of solid phases (Cr-rich spinets, (Fe, Mg) (Al, Cr. Fe) 2O4) from a liquid and their accumulation into chromite-rich layers. The processes involved in the formation of chromite layers are fractional crystallization and gravity settling.
