Jan 01, 2006 Fig. 1 provides an illustrative flowsheet of the traditional process used for producing chromic oxide (Cr 2 O 3) from chromite ore.During the initial stage, insoluble chromite ore is converted into water-soluble chromate. Roasting a mixture of chromite ore, sodium carbonate (Na 2 CO 3), limestone, and dolomite at 1100 C for several hours produces sodium chromate (Na 2 CrO 4).
But it is used for than the production of stainless steel and nonferrous alloys it is also used to create pigments and chemicals used to process leather.

Magnetic separation is an important beneficiation process and is usually adopted for ores of manganese, phosphate, titanium, chrome, tungsten, molybdenum, nickel, bauxite and niobium-tantalum ores in addition to iron ores,,,,, .Magnetic separation methods were also carried out for the ferrochrome industry wastes such as the flue dust to find.
Chromite ore processing residue (COPR) is a waste byproduct of chromate production that contains high levels of hexavalent chromium (Cr[VI]). Although the high temperature chromite process was banned in several countries, its legacy still exists at numerous contaminated sites. For instance, New Jersey alone has over 2 million tons of waste COPR.
Typical chromite process flowsheet In some cases, chromite concentrates can be produced by wet gravity concentration alone. In other chromite beneficiation processes, magnetic separation by RED is an essential polishing step.
