It is widely spread through serpentine rocks at many places, notably in Brussa, Asia Minor; at Banat and elsewhere in Norway; at Solnkive, in Rhodesia; in the northern portion of New Caledonia; at various points in Macedonia; in the Urals, Russia; in Beluchistan and Mysore, India. The annual production of chromite in the world is large, as it is an important industrial mineral. Major producers currently include South Africa, Turkey and India.
It is found at many locations but only sparingly in the United States. In the United States the mineral is known at several points in a belt of serpentine on the east side of the Appalachian Mountains, and at many points in the Rocky Mountains, the Sierra Nevada and the Coast Ranges. It has been mined at Bare Hills, Maryland; in Siskiyou, Tehama and Shasta Counties, California; in Converse County, Wyoming; and in Chester and Delaware Counties, Pennsylvania; and; in 1914, some was washed from chrome sand at Baltimore, Maryland. Small amounts were historically produced in the certain states of the US, including Pennsylvania, Maryland,North Carolina Montana, Oregon and California and Wyoming.
