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 was first discovered in the United States at Bare Hills, Md., around 1810. Between 1820 and 1850, additional deposits were discovered and mined in Maryland and Pennsylvania, including the largest deposit of massive chromite ever found in the United States the Wood deposit, in the State Line district.

Chromium is not mined in the United States. The chromium consumed by United States industry comes from A) other countries in the form of chromite ore, ferrochromium or chromium metal or, B) chromium recovered from recycled metals. Over half of the chromium used in the United States today is from recycling.
Chromite is a relatively common ore mineral in the Coast Ranges, Sierra Nevada, and Klamath Mountains, and California is the leading producer of the mineral in the United States. Name is from the Greek word chroma, meaning color, for the brilliant hues of its compounds.
In 2020, the United States was expected to consume 4% of world chromite ore production in various forms of imported materials, such as chromite ore, chromium chemicals, chromium ferroalloys, chromium metal, and stainless steel. Imported chromite ore was consumed by one chemical firm to produce chromium chemicals.
Domestic Production and Use In 2019, the United States was expected to consume 4% of world chromite ore production in various forms of imported materials, such as chromite ore, chromium chemicals, chromium ferroalloys, chromium metal, and stainless steel. Imported chromite ore was consumed by one chemical firm to produce chromium chemicals.

Another factor driving the growth of the chromite market is the demand for chromium for electroplating in mining companies. Chromite is also used as pigments, catalyst, leather tanning and is widely used in the refractory market. South Africa remains the largest source in the world for Chromite, accounting for 72% of the worlds reserves.

Chromite mining in the United States ceased in 1961 (ATSDR, 2000). Native chromium deposits are rare however, some native chromium metal has been discovered. The Udachnaya Mine in Russia is a kimberlite pipe rich in diamonds and produces samples of the native metal.
Relation to Mining While China is the leading chromium-consuming country and the leading stainless steel producer, it is not a large producer of chromite ore. The United States, Kazakhstan, India and South Africa are the largest chromite-mining countries in the world.
The South Kaliapani chromite mining area alone contributes about 97% of the total chromite reserve of the state (IBM, 2010).The chromite ore belt at Sukinda is spread over an area of approximately 200 sq. km. in Jajpur district and is well-known chromite hub in

At present the United States Government is purchasing chromite ore and concen-trates at incentive prices under the Minerals Stockpile Program. For domestic chro-mite delivered to Grants Pass, Oreg., the General Services Administration offers $115 per long dry ton of lump ore and $110 per long dry ton of fine ore or concen-
United States has no domestic production or economic reserves of the only commer cial ore of chromium, chromite, and must rely on imports to meet national needs. The chemical industry uses approximately 25 pct of the chromite consumed in the United States for the production of pig

The economic potential of chromite deposits depends mainly on the thickness, continuity, and grade of ore. The most important uses of chromium are in stainless steels, nonferrous alloys, and chromium plating. Chemical- grade chromium is widely used in chemicals and pigments. Chromium also is an important component in refractories.
