Chromite ore beneficiation is the process of separating the valuable minerals from the waste rock and impurities in the ore to produce a concentrated and purer form of chromite that can be used
Chromite ore is the primary source of chromium India has large reserves of chromite which is about million tons Orissa alone accounts for million tons and most of it is located in
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
Magnesium frequently substitutes for iron in chromite A solid solution series exists between the mineral chromite FeCr 2 O 4 and the isomorphous mineral magnesiochromite MgCr 2 O 4 Intermediate specimens can be rich in iron Fe Mg Cr 2 O 4 or magnesium Mg Fe Cr 2 O 4 For convenience in communication these minerals are often referred to collectively as
