The Antimony Refining (Primary) industry is in the Primary Nonferrous Metals, nec category, and the Primary Metal Industries sector. With 7 companies, this industry employs approximately 75 people in the United States. The Antimony Refining (Primary) industry is disproportionally concentrated in the states of Indiana, Iowa, Montana, and New York.
The refined metal is then ladled out and cast as " star antimony," the surface of the cakes showing a well-defined crystal structure. A method has also been suggested for refining electrolytically using an electrolyte containing antimony trifluoride with about 100 grams of free sulphuric acid and 20 grams of free hydrofluoric acid per litre.
