The stibnite concentrates are then fumed to a crude oxide that is either fumed to a finished oxide or reduced to metal and then fumed to finished oxide. Tetrahedrite concentrates are usually leached in alkaline solutions that are electro-won to recover antimony metal or oxidized to sodium antimonite.

Production process. The extraction of antimony from ores depends on the quality and composition of the ore. Most antimony is mined as the sulfide; lower-grade ores are concentrated by froth flotation, while higher-grade ores are heated to 500–600 °C, the temperature at which stibnite melts and separates from the gangue minerals.
