what is difference chrome and chromite

Chromite - WikipediaChromite is an iron chromium oxide: FeCr2O4. It is an oxide mineral belonging to the spinel group. Magnesium can substitute for iron in variable amounts as it forms a solid solution with magnesiochromite (MgCr2O4); substitution of aluminium occurs leading to hercynite (FeAl2O4). It is by far the most industrially important.what is difference chrome and chromite,Refractory- and metallurgical-type chromite ores, Zambales ophiolite .Refractory and metallurgical chromite deposits are spatially separated and related to different lithologic associations, which crystallized from different parental . composition of chromite within the deposits varies depending on the chromite/silicate ratios of the ore types and grades continuously into accessory chrome spinels.
