Chromite, relatively hard, metallic, black oxide mineral of chromium and iron (FeCr2O4) that is the chief commercial source of chromium. It is the principal member of the spinel series of chromium oxides; the other naturally occurring member is magnesiochromite, oxide of magnesium and chromium (MgCr2O4). Chromite is commonly found as brittle masses in peridotites, serpentines, and other basic igneous and metamorphic rocks; an unusual occurrence is as a crystalline inclusion in diamond.

Chromite is an oxide mineral composed of chromium, iron, and oxygen (FeCr2O4). It is dark grey to black in color with a metallic to submetallic lustre and a high specific gravity. Chromium is a metal used to induce hardness, toughness, and chemical resistance in steel. It produces an alloy known as "nichrome" which is resistant to high temperatures and used to make heating units, ovens, and other appliances. Thin coatings of chromium alloys are used as platings on auto parts, appliances, and other products.

Chromite sand is characterised by:

• High melting point
• Excellent thermal stability
• High density 
• Medium Mohs hardness of 5.5

Application of Chromite:

Foundry, Pigment, Friction Brake Lining, Glass Containers, Construction, Chemical
