Chromite is a mineral in the form of granular masses whose commercial ores contain 35-68% of chromite oxide. Its color changes from black-brown to iron-black with a metallic sheen, and its specific gravity is 4.6 grams per cubic centimeter and its hardness is 5.5. Chromite has a melting point of 2130 degrees Celsius. The quality of the mineral is measured on the basis of the ratio that if the ratio is less than 2, the stone is substandard and if it is more than three, it is good.
