Scrap iron from an iron foundry in China with a diameter of about 2 mm was used without further pretreatment. The experiment was performed in conical flasks covered with lids. After 0.025 g scrap iron was added to 500 mL of Sb(V) solution, the residual Sb and SO 4 2− in solution were analyzed. To investigate the influence of solution pH on Sb ...

Antimony (Sb) is obtained by heating pulverized stibnite (Sb2S3) with scrap iron and drawing off the molter antimony from the bottom of the reaction vessel. Suppose that 6 kg of stibnite and 2.5 kg of iron turnings are heated together to produce 2 kg of Sb metal. MW of Sb2S3, Fe, and Sb are 339.7, 55.85, and 121.8 respectively.

While the antimony metal is a very brittle, silvery, moderately hard metal, the non-metallic form is a grey powder. The shell structure of element 51 is 2.8.18.18. The atomic structure of antimony is relatively stable in dry air, and this chalcophile is unreactive when exposed to dilute acids or alkalis.

The sulphide is removed to leave elemental antimony with scrap iron. Sb 2 S 3 + 3Fe → 2Sb + 3FeS. In antehr process, some ores can be heated to evolve the oxide Sb 2 O 3 and this in turn can be reduced by charcoal in the presence of sodium sulphate, to ensure mixing, to form elemental antimony. 2Sb 2 O 3 +3C → 4Sb + 3CO 2
