CHROMITE – Encyclopaedia Iranica

CHROMITE, FeCr 2 O 4, a dark-brown or black mineral from which chromium is refined. It may be found in conjunction with deposits of nickel, gold, and platinum. There is no available documentary evidence that chromite was extracted or exploited in ancient Persia; it was probably not used in metalworking because of its high melting point (2,300-2,600° F.), compared with those of copper and lead.

Optical properties of Ore Minerals

The physical properties of ore minerals observed in polished sections are of great assistance in mineral identification, and hence their study is routine in ore microscopy. The most useful and easily observable physical properties are crystal form and habit, cleavage and parting, twinning, zoning, inclusions and intergrowths and hardness.

Chromite: from the mineral to the commodity

Lode chromite ore deposits comprise stratiform and podiform deposits, whereas secondary chromite ore deposits comprise laterite and placer deposits. Chromite is an important industrial mineral used in the refractory industry.
