Oxide mineral,spinel group,spinel structural group

Chromite is a mineral oxide. It has a chemical formula of FeCr2O4. It is an oxide mineral. The element magnesium in variable amounts as it forms a solid solution can also occur, leading to hercynite Chromite today is mined particularly to make stainless steel through the production of ferrochrome (FeCr), which is an iron-chromium alloy.

Chromite grains are commonly found in large mafic igneous intrusions such as the Bushveld in South Africa and India. Chromite is iron-black in color with a metallic luster , a dark brown streak and a hardness on the Mohs
