Chromite mining The Oregon Encyclopedia

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.

Chrome Ore Beneficiation Process Chromite JXSC Mining

The dissociation degree of chromite monomer in the sample is 95.11%, the magnetism can be used to separate the chromite from the nonmagnetic ores. The gangue minerals, such as enstatite, tremolite, diopside, biotite, also have weak magnetism, affect the grade of magnetic concentrate. It is better to separate it by using gravity separation.
