Abstract:
     According to this method, antimony sulphide is placed in a fire-resistant pot to react at a certain temperature. Antimony metal is produced directely. SO2 released during the reaction is absorbed by lime and/or semi-calcined dolomite. This method has many advantages in energy-saving, nopollution of environment, noncorrosive to equipment, ease of operation needing less-investment and giving quick-return. This invention is suitable for factories, mines or village-town enterprises.
