Chromite is the major mineral form of chromium; all chromium and chromium compounds prepared in the United States are from imported chromite ores. Importation is considerably more economical than mining the U.S. chromite deposits, most of which have a low chromium con- tent. About 75% of the imported ore comes from the U.S.S.R. and South Africa.
