What is Chromite Used For? Occurrence and Uses of Chromite

Feb 10, 2021  An important use of chromite is in the manufacture of refractories, largely in the form of chromite brick. Raw chromite ore is used directly for this purpose. The ore is ground, mixed with a binder, and pressed into bricks under a pressure of 10,000 to 15,000 psi (about 700-1,000 kg per sq cm).

Chromite - Wikipedia

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. The vast Bushveld Igneous Complex of South Africa is a large layered mafic to ultramafic igneousbody with some layers consisting of 90% chromite making the ra
