Chromite is the only economic source of Chromium. It has a wide range of uses in metallurgical, chemical, refractory industries. The properties of chromium that makes it most versatile and indispensable are its resistance to corrosion, oxidation, wear and galling and enhancement of hardenability.
In metallurgical industry, chromite is used for manufacturing low-carbon and high-carbon ferro-chrome and charge chrome which in turn are used as additives in making stainless steels and special alloy steel. Hard lumpy chromite is used for producing high carbon ferro-chrome while friable ore and fines briquettes are used for low carbon ferrochrome. Both briquetted fines and lumpy ores are used in production of charge chrome.
About 77% of the total world resources are located in South Africa, followed by Kazakhstan 6%. The other important countries possessing chromite resources are Zimbabwe, Finland, India, Brazil, Turkey, Albania, Russia, United States and Iran.
