Oxidizing Roast; Stibnite the Antimony Mineral

The leading antimony mineral is stibnite. In smelting stibnite ore two processes are available, precipitation and roastingreduction. The former is suited, only for highgrade ores. As lowgrade ores are more common than highgrade, roastingreduction is of greater importance than precipitation. In the roasting process the aim may be to leave the oxidized antimony in the ore, or it may be to ...
