converting metal from antimony ores

The volatilisation and oxidation of antimony trisulphide have been studied in detail From the results it is suggested that rich or concentrated ores which do not contain precious metals arsenic or lead should be roasted to antimony tetroxide while poorer ores and ores containing precious metals should be roasted to antimony trioxide
