2020-6-2The leading antimony mineral is stibnite. In smelting stibnite ore two processes are available precipitation and roasting-reduction. The former is suited only for high-grade ores. As low-grade ores are more common than high-grade roasting-reduction is of greater importance than precipitation. In the roasting process the aim may be to leave the oxidied antimony in the ore or it may be to
Antimony is often found in other ores as well e.g. silver copper and lead. The pure element antimony is produced from the ore by roasting it to form the oxide then reducing the oxide with carbon or iron often a flux of sodium sulfate or sodium carbonate is used to prevent loss of molten antimony by evaporation

It is obtained from antimony ore by a roasting process or by oxidiing metallic antimony and subsequent sublimation and is used for the manufacture of tartar emetic as a paint pigment in enamels and glaes and as a flameproofing compound
Read MoreRoasting of sulfides in general is exothermic and hence the temperature of the ore lump remains high enough for the desired chemical reactions to occur fairly early during the roasting process. This chapter also attempts to demonstrate as to how the predominance area diagrams of CuSO and FeSO systems were used in the past for the
