Stratiform, Podiform, and Beach Sands. Small amounts of chromite are found in many types of rock. However, chromite deposits that are large enough for mining are generally found in: 1) stratiform deposits (large masses of igneous rock such as norite or peridotite that slowly crystallized from subsurface magma); 2) podiform deposits (serpentines and other metamorphic rocks derived from the

Chromite Exploration Spectral Evolution

Chromite is the only ore for chromium, a hard corrosion resistant metal that can be polished, has a high melting point and is used primarily as a coating/finish for stainless steel. Its yellow color is also used in pigments. Chromite is part of the spinel group of minerals. Chromite is associated with the minerals olivine, magnetite, serpentine, and corundum. It is found in two deposit types

20/07/2017 Chemical-grade chromite ore generally ranged from 40 to 46 pct Cr2O3 with a chromium-to-iron ratio of 1.5:1 to 2:1. Refractory-grade chromite ores contained a minimum of 20 pct Al2O3 and more than 60 pct Al2O3 plus Cr2O3. Primary chromium needs for all uses in the United States by the year 2000 are estimated to be nearly three times its present annual consumption (400,000 short tons),

Chromite

Chromite is found as orthocumulate lenses of chromitite in peridotite from the Earth's mantle.It also occurs in layered ultramafic intrusive rocks. In addition, it is found in metamorphic rocks such as some serpentinites. Ore deposits of chromite form as early magmatic differentiates. It is commonly associated with olivine, magnetite, serpentine, and corundum.
