Antimony (Sb) is a troublesome impurity in the tin (Sn) smelting process. Generally, the Sb content in a Sn concentrate is 0.01–0.5%, and approximately 95% Sb is mixed with crude Sn after reduction and smelting [1, 2].During crude Sn pyrorefining, Sb and aluminum (Al) are used to generate high melting point compounds with densities much lower than that of Sn, …

Tin forms two chlorides: tin (II), or stannous, chloride (SnCl 2), and tin (IV), or stannic, chloride (SnCl 4). Tin (II) chloride is a white, soluble solid, which can be produced by dissolving tin in hydrochloric acid. It is used as a reducing agent and also as a constituent of tin-plating electrolytes. Melting point 246°C, boiling point 652°C.

The smelting of tin involves two cycles: primary and secondary. In the primary cycle, a high FeO content is desired in the slag. This produces a hardhead high in iron for the secondary cycle. There, a high ratio of FeO to SnO in the slag is needed for economic smelting. Lime is added but limited to control slag volume, while the iron introduced must report to the secondary slag.
