Chromite Wikipedia

Chromite is a mineral that is an iron chromium oxide.It has a 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 also occur, leading to hercynite (FeAl 2 O 4).

Chromite: The only mineral ore of chromium metal

What is Chromite? 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 weathering.

Chrome Flour Glass Application African Pegmatite

Our iron chromite naturally contains between 44% and 46% chrome, with a maximum 3% silica and the perfect chrome-to-iron ratio (1:1.5). The raw material is milled to an ultra-fine powder, 98% below 45 micron/ 325 mesh. This allows for better dispersal during your mixing processes and eliminates speckling.
