Abstract
273,440. Harris, H. May 7, 1926. Sodium stannate; sodium arsenate.-Mixtures of sodium stannate and sodium arsenate, with or without sodium antimonate, are treated, in the cold with caustic soda solution of such strength as to dissolve only the sodium stannate, the resulting solution being separated from the residue, and the latter being treated for the recovery of pure sodium arsenate. When treating mixtures consisting only of sodium stannate and arsenate, the solution used may contain from 100 to 250 grms. of caustic soda per litre, but when the mixtures contains free caustic soda, and salts such as sodium chloride or sodium carbonate, as is the case, for instance, with mixtures obtained by the processes described in Specifications 213,638 and 245,479, the strength of the caustic soda solution may be reduced. For example, a mixture containing 5.1 per cent sodium chloride, 5.8 per cent sodium carbonate, and 3:5 per cent caustic soda, may be treated with a solution containing 58 grms. of caustic soda fer litre.
