Chromite: The only mineral ore of chromium metal

What is Chromite? Chromite is an oxide mineral composed of chromium, iron, and oxygen (FeCr 2 O 4).It is dark gray to black in color with a metallic to submetallic luster and a high specific gravity. It occurs in basic and ultrabasic igneous rocks and in the metamorphic and sedimentary rocks that are produced when chromite-bearing rocks are altered by heat or weathering.

Chromite an overview ScienceDirect Topics

Chromite ore is one of Turkey's major income sources in primary mineral exports. Ferrochrome production of Turkey was different between 2007 and 2011, at 69.73–60.00 metric tons. The demand for chemical-type ores has also increased with the operation of sodium bichromite-producing factories.
