Extraction of Chromium from Chromite Ore
The chromite grains in both samples were essentially liberated from the gangue at 100 mesh, although chromite was still locked with magnetite particles as small as 400 mesh. Both samples also contained fibrous structured minerals that may present environmental and/or health problems in the event of commercial mining and/or processing.

CHROMITE (Iron Chromium Oxide)
Chromite is the most important ore of chromium from which it derives its name. Chromium is an important metal and has a wide range of industrial uses. Chromite forms in deep ultra-mafic magmas and is one of the first minerals to crystallize. It is because of this fact that chromite is found in some concentrated ore bodies.
