    Chromite Mining The Oregon Encyclopedia

    Chromite is a mineral that contains chromium. It is considered a strategic mineral, which generally means that it is necessary for military and industrial use during periods of national emergency. The strategic mineral concept was created during World War I and became law just prior to World War II with the passage of the Strategic Minerals Act of 1939.

    Chromite Department For Energy And Mining

    Chromite, a brownish black cubic mineral belonging to the spinel group, is the only ore mineral from which metallic chromium and chromium compounds are obtained. It has the chemical formula FeCr 2 O 4, and a theoretical composition of 32.0% FeO and 68.0% Cr 2 O 3. In its natural form it occurs in solid solution with other minerals in the spinel group, so chrome contents are less than the theoretical 68%.
