Chromite: The only mineral ore of chromium metal

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.

Chromite: Mineral information, data and localities.

Chromite is the most important chromium ore mineral. It forms a complete solid solution series with many other members of the group, eg. in the Chromite-Hercynite Series, Chromite-Spinel Series, Chromite-Magnetite Series and the Chromite-Magnesiochromite Series.It is the iron analogue of Zincochromite, Cochromite, Manganochromite and Magnesiochromite and the Cr analogue of Hercynite

Chromite ores of certain deposits contain minerals of the platinum group (Ir, Ru, Pt, Pd, and Rh), especially in South Africa and Zimbabwe, often found as inclusions in chromite silicate matrix. The mineral and gangue components have different magnetic susceptibilities, which makes it possible to use various magnetic separation methods.

Chromite. From 1988 to 1990 -- on the average -- most of the chromite-producing companies experienced a relative boom, as reflected by the increases in their extraction. For the said period, the total chromite ore extraction grew at an annual average of 30.1 percent, despite the earthquake that jolted Luzon island in July 1990.
