3.1 Chrome magnetic separation process. The chrome raw ore is a flotation tail ore, which is mainly formed in the chromite, and the chromite is the target recovering mineral. The dissociation degree of ferrochromium ore is low, and it has a weak magnetic property. First of all, magnetic separation processing to separate chromite.

Chromium contained in contaminated soils and solid wastes can be categorized as exchangeable, oxidizable, carbonate-bound, reducible and residual. The results from this study indicate a need for efficient leaching methodologies in chromite ore processing plants to decrease the non-detrital fractions of chromium in the residue.

Chromium metal is obtained commercially by heating chromite ore in the presence of carbon, aluminum, or silicon, and subsequent purification (ATSDR, 2000). Sodium chromate and dichromate are produced by roasting chromite ore with soda ash and are the primary chromium salts from which most other chromium compounds are derived (ATSDR, 2000).
