Specifications of Chromite
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 FeCr2O4. 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 (MgCr2O4). A substitution of the element aluminium can also occur, leading to hercynite (FeAl2O4). Chromite today is mined particularly to make stainless steel through the production of ferrochrome (FeCr), which is an iron-chromium alloy.
Chromite grains are commonly found in large mafic igneous intrusions such as the Bushveld in South Africa and India. Chromite is iron-black in color with a metallic luster, a dark brown streak and a hardness on the Mohs scale of 5.5.
The chromium extracted from chromite has a lot of benefits when it comes to its uses and applications. The use of chromium in anthropogenic processes can develop considerable health and environmental impacts around the world.
HopeSA Holding Trade started to invest in mining industry and Chromite mine in South Africa from 2015.
Chromite mainly export from South Africa to China and used for ferro chromite production in China.
