Abstract

The chlorination of domestic tin-plated scrap was studied to determine the potential of this material as a source of tin for the manufacture of stannous chloride. It is found that tin-plated crap chlorinated in a preferential manner at a temperature of 298 K and iron did not react with chlorine at this temperature. It has been demonstrated on a laboratory scale that it is feasible to separate tin from tin coated scrap as high purity SnCl₂ crystals by chlorinating in Cl₂/N₂ gas mixtures, and as illustrated in Table 3, the SnCl₂(s) obtained in this work has the same high purity that of those produced by some commercial laboratories. The results show that tin-plated scrap has good potential as raw material for the manufacture of stannous chloride by selective chlorination.
