Chromite: The only mineral ore of chromium metal

Chromite is important because it is the only economic ore of chromium, an essential element for a wide variety of metal, chemical, and manufactured products. Many other minerals contain chromium, but none of them are found in deposits that can be economically mined to produce chromium.

Chromite mining in India started around 1903 there was no ferro chrome production in the country till 1968. Hence most of the chromite ore was exported. India exported about 3.84 million tonnes between 1903 to 1980. The current production rate of chromite ore in the country is between 0.7 to 0.9 million tonnes per annum.

Chromite Exploration Spectral Evolution

Chromite is the only ore for chromium, a hard corrosion resistant metal that can be polished, has a high melting point and is used primarily as a coating/finish for stainless steel. Its yellow color is also used in pigments. Chromite is part of the spinel group of minerals.

Chromium processing Britannica

Chromite deposits are mined by both underground and surface techniques. Much of the ore is rich enough to be used directly: for production of ferrochromium, a rich, lumpy ore containing more than 46 percent Cr 2 O 3 and having a chromium iron ratio greater than 2:1 is preferred, but ores with a lower ratio and as little as 40 percent Cr 2 O 3 are also used. Ores high in alumina are preferred for

Uses of Chromium Supply, Demand, Production, Resources

Chromite is used in high temperature applications, such as blast furnaces and molds for firing bricks, because it retains strength at high temperature. Chromium is also vital for good health. Insufficient amounts result in glucose intolerance in humans. Organ meats, mushrooms, wheat germ, and broccoli are all good dietary sources of chromium.
