Large tonnages of chromite tailing were discarded during processing of chromite ore in the conventional circuit. A typical chromite plant tailing was treated in table for the recovery of chromite values. Optimisation study was carried out for the process parameters of table using empirical models, developed from the experimental data.

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. Low-grade ore obtained from an open cut trench at a chromite deposit near Auburn, Calif., was treated in the laboratory using gravity-magnetic separation and flotation beneficiation techniques. Flotation using known methods, however, gave very poor results and will not be discussed further in this report.

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.

Most of the ore mined at the Donskoy Ore Mining and Processing Plant is supplied to ferroalloy plants in Aksu and Aktobe. Ore with a high chromium oxide content (up to 62% Cr 2 O 3) is used to produce ferroalloys in metallurgy, as well refractory products, and chromium compounds in the chemical industry.
