Chromite mining The Oregon EncyclopediaDomestic 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. Without government support, most chromite Chromite Chromite 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 so
