Abstract
Tin is dissolved from tin-plate and other materials containing tin by treating with a solution of ferric or stannic chloride or both, with reduced pressure and with or without agitation. The saturated solution is then divided so that the total tin in one part is equal to the tin that has been dissolved by the whole, and this part is then treated to recover the tin either as metal, oxide, or sulphide. The rest of the solution is oxidized in presence of hydrochloric acid and used again. The precipitation of tin oxide may be effected with magnesia, the magnesium chloride being then heated to regenerate magnesia and obtain hydrochloric acid and chlorine which is used in the oxidation of the solution which is to be reused. Specification 159,659 is referred to. The Specification as open to inspection under Sect. 91 (3) (a) includes the treatment of the tin material with the solution with agitation without reduced pressure. This subject-matter does not appear in the Specification as accepted.
