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.

Chromite is the principle ore of the element chromium. Chromite is a key industrial mineral used for manufacturing stainless steel because of its very high melting point. Rock Containing Chromite Ore Extraction of the Chromite Ore Both surface and underground mining methods will be used to mine the chromite. Mining produces both ore and waste rock.

The most commonly used beneficiation methods for chromite ores are the gravity methods, such as the shaking table, jig, spiral and Reichert cone methods. The present work deals with the geologic studies that, coming after prospection, lead to the evaluation of the chromite ore quality and to planning and/or improvement of beneficiation plants.

Chromium Mining. Chromium is the brittle, lustrous and hard chemical element that belongs to the group of spinel. 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.

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
