What is Chromite

Chromite is an oxide mineral. The main composition of Chromite is chromium along with iron and oxygen. It is the only ore of Chromium. The color of chromite varies from grey to black  and has a sub-metallic lustre with a high specific gravity. Chromite is relatively hard and metallic. It is found in basic and ultra-basic igneous rocks or metamorphic rocks and even sedimentary rocks. Their occurrence is a result of altering of these rocks by heat or weathering.

Being the only ore of chromium, chromite is highly used in the production of stainless steel, nichrome and chrome plating. Given it's high heat stability, it is also used as a refractory material.
