Chromite is the commercial name for iron chromium oxide (FeCr2O4), mineral containing chromium (a transition metal with multiple oxidation states) and iron oxide. In its purest form, chromite comprises chromium (Cr2O3) at 68% and iron oxide (FeO) at 32%. Chromite is the only ore mineral of metallic chrome. 

 

Chromite occurs exclusively in ultramafic rocks such as dunite, peridotite, pyroxenite and

serpentinite. High purity deposits are rare owing to replacement by certain elements. In nature, ferrous iron tends to be partially replaced by magnesium, while chromium may be partially replaced by aluminum or ferric iron. As a result, a range of chromite grades can occur in any deposit, with each grade suitable for a specific application.

Chrome plays an essential but hidden role in human life. In many ways, chromium contributes to a clean, efficient, and healthy life style. Chromium is the principal alloy material for the production of stainless steel. Many consumer products use chromium and many others are made possible by industrial use of chromium. Industry useschromium in three forms, ferrochromium, chromium chemicals, and chromite ontaining refractories to make industrial products, which in turn may end up in consumer products.

Other important sources of chromite include Zimbabwe (with 12% of the world’s reserves), Kazakhstan (4%), Finland (2%), India (1%) and smaller amounts in Turkey and elsewhere. World production of chrome ore totalled 23.8m. Tonnes in 2008 and was dominated by South Africa (41%), followed by India (16%), Kazakhstan (15%), Turkey (8%), and Oman (3.5%).
