Chromite: The only mineral ore of chromium metal

Chromite is an oxide mineral composed of chromium, iron, and oxygen (FeCr 2 O 4 ). It is dark gray to black in color with a metallic to submetallic luster and a high specific gravity. It occurs in basic and ultrabasic igneous rocks and in the metamorphic and sedimentary rocks that are produced when chromite-bearing rocks are altered by heat or ...

Chromite - Wikipedia

Chromite is a crystalline mineral composed primarily of iron(II) oxide and chromium(III) oxide compounds. It can be represented by the chemical formula of FeCr 2 O 4.It is an oxide mineral belonging to the spinel group.The element magnesium can substitute for iron in variable amounts as it forms a solid solution with magnesiochromite (MgCr 2 O 4). A substitution of the element aluminium can ...

What is magnetic separation? - ChemistryRack

The magnetic separation is a physical separation technique which is based mixtures or using the magnetic properties of the material, such as its sensitivity to the attraction or repulsion magnets. It is also known as magnetization, because the objects that can be separated by this technique are magnetized by the magnetic field of the magnets.

Conventionally, the chromite ore beneficiation is carried out using gravity concentration techniques. As the particle size decreases, the separation of the chromite particles by gravity separation becomes difficult because of the presence of near-density gangue minerals. In addition to magnetic sepa-ration, flotation has also been incorporated into the process to recover the fine chromite ...
