Chromite ore processing residue (COPR) containing measurable levels of hexavalent and trivalent chromium. [Cr(VI) and Cr(III), respectively] has been used to fill in low-lying areas in Hudson County, N.J. While it has been demonstrated that direct dermal contact with solutions containing Cr(VI) may elicit allergic contact dermatitis (ACD) in
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.
Chromium mining and processing In nature, chromium is found as chromite ore, composed of elemental iron, oxygen and chromium (FeOCr 2 O 3). 1,2 heavily in about a 700 m vicinity around the Countries with commercially significant chromite mines include Russia, South Africa, Zimbabwe, Turkey, the Philippines and India.2 Chromite ore is initially

50tph Chrome & chromite ore processing plant in Philippines. The mine is lump ore, first the raw ore into the crusher, then to the ball mill to grind the ore...
It is suspected that “clean granular inorganic fill material” was used as a euphemism for “chromite ore processing residual.” The Baltimore Chrome Works plant operated from the 1800s until 1986 at the site in Fells Point. Until 1954, Mutual Chemical Company and its predecessors operated the plant. In 1954 the plant was acquired by
Chromite. Chromite ore is predominantly used in the production of ferrochrome – an alloy of chrome and iron, containing between 50% and 70% chromium. The production of steel is the largest consumer of ferrochrome, especially stainless steel production which contains between 10% and 20% ferrochrome content. The process of chromite ore mining

Since recoveries are generally very poor in the fine sizes, the gravity flowsheet must be
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.
