Tin Recovery as Stannous Chloride by Chlorination of Tin-Plated Scrap at 298 K

摘要

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 SnCl 2 ) crystals by chlorinating in Cl 2 ) /N 2 ) gas mixtures, and as illustrated in Table 3,?the SnCl 2 ) (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.
