The mining method used for extracting chromite depends greatly on the characteristics of the deposit. These characteristics include whether it is stratiform or podiform, high grade or low grade, subsurface or near surface, or massive or disseminated. Because surface mining typically is less expensive than underground mining, it is preferred

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).
