Domestic mining for chromite was restricted to a few locations in the United States, including Montana, California, and Oregon, and mining the mineral was only economically feasible during times of political conflict. During wartime, the United States government supported domestic production with price supports and strategic stockpiling programs

Surface Mining Chromite ore is mined frst by surface methods. This includes an open pit from which surface material, non-chromite bearing overburden and chromite ore, will be excavated. The chromite ore containing rock will be drilled, blasted, removed and loaded onto large trucks for hauling to the crusher and ore processing facility

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

Mihail I. Gasik, in Handbook of Ferroalloys, 2013 8.2.3 Chromium Ores and Chromites Processing. Chromite ores, as might many others, be mined by open-pit and underground methods. The share of underground mining varies between countries and deposits. The extracted ore is subjected to crushing and sorting (normally rich ore containing more than 45% Cr 2 O 3 is supplied to the processing plant
