Chromite is the only ore of chromium, a metal essential for making stainless steel, nichrome, chrome plating, pigments, refractories, chemicals and pharmaceuticals.
Chromite is the mineral ore of the metal Chromium, and the chromium must often be extracted from the ore and purified before it is used. Chromium is an important ingredient in steel; it gives this metal increased hardness and toughness, and it helps it reduce chemical erosion over time.
The microtexture of the ore is, however, dominated by numerous intergrowths between chromite and ilmenite. The ilmenite occurs as rounded" granu lar grains and as lamellae. The first type of ilmenite appears as rounded anhedral grains averaging 100 pcm across.
