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.
