Transcribed image text: In the metallurgy of antimony, the pure metal is recovered by different reactions, depending on the composition of the ore. For example iron is used to reduce antimony in sulphide ores: Sb_2 S_3 (s) + 3Fe (s) rightarrow 2 Sb (s) + 3FeS (s) delta H = -125 kJ Carbon is used as the reducing agent for oxide ores: Sb_4 O_6 (s) + 6C (s) rightarrow 4Sb (s) + 6CO (g) delta H ...

Antimony sulfide deposits are easy-to-float deposits, and flotation methods are mostly used to improve the crystal position of the ore. In the meantime, stibnite often uses lead salts as activators first, and also uses copper salts or both lead salts and copper salts, and then uses collectors for flotation.

Much of the ore is stibnite, with quartz as a minor impurity, and assays show the tenor to vary from 40 to 65 percent antimony. Sulphantimonites are less abundant but likewise occur as disseminated crystals and as kidney-shaped bodies. Antimony oxides appear on the weathered surface and along fractures within the sulfide ore.
