Abstract

1,250,863. Detinning tinned iron sheet. T.H. GOLDSCHMIDT A.G. Feb.19, 1970 [Feb. 20, 1969], No. 8114/70. Heading C7D. [Also in Division C1] Tinned iron sheet is detinned by treating it with a caustic soda solution containing NaClO 2 as an oxidizing agent. The solution may be at 50- 100‹C. and air may be passed therethrough. The amount of NaClO 2 in the solution is preferably the molar equivalent of the tin to be removed. The dissolved tin may be precipitated as stannic acid or hydrated stannic oxide, the precipitate washed and dissolved in caustic soda to form a solution which may be electrolyzed to recover Sn or used for producing sodium stannate.
