Chromite grains are commonly found in large mafic intrusions and are also found in metamorphic rocks on the earth’s crust. Chromite, which is an iron chromium oxide (FeCr2O4) is the only ore present to produce the element chromium.
Read MoreThe 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 ...
