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 ...

Metallurgy - Definition & Process | Principles of Metallurgy

Metallurgy process involves the refining of metals and the production of alloys of metals. The impurities present in the ore, which has to be separated in order to obtain desired metal from its ore during the process of extraction, are called gangue. A substance added in the furnace to remove the gangue present in the ore is called flux.
