Chromite Ore, Moisture : 3.00% Max

Chromite is an oxide mineral composed of chromium, iron and oxygen (FeCr2O4). It also can be found as in a composition to magnesium instead of iron and become the magnesiochromite (MgCr2O4).
It is a dark gray to black in color with a metallic to sub-metallic luster and a high specific gravity. It occurs in basic and ultra basic igneous rocks and in the metamorphic and sedimentary rocks that are produced when chromite-bearing rocks are altered by heat or weathering.
Chromite is important because it is the only economic ore of chromium, an essential element for a wide variety of metal, chemical and manufactured products. Many other minerals contain chromium, but none of them are found in deposits that can be economically excavate to produce chromium.
