Abstract
Arsenic, antimony, and tin are separated from caustic soda, for instance from the soda used for refining lead by the process described in Specification 189,013, [Class 82 (i), Metals, Extracting &c.], by treating the mass with hot water, separating the lead and insoluble antimonate, and cooling to separate crystals of sodium arsenate and stannate. The stannate is only satisfactorily separated in presence of excess of arsenate, and additional arsenate may therefore be added if necessary to secure that the ratio of arsenic to tin in the solution is at least 3 : 1. The mixed crystals are dissolved in water and treated with calcium carbonate to precipitate calcium stannate then with lime to precipitate calcium arsenate, then with more base to caustify the soda; or first with enough lime to precipitate calcium stannate and then with more lime to precipitate calcium arsenate and stannate together.ALSO:Arsenic, tin and antimony are separated from caustic soda, for instance from the mass resulting from refining lead by the process described in Specification 189,013, by treating the mass with hot water, separating the lead, separating the suspended antimonate from the dissolved arsenate and stannate, and cooling the solution to separate the arsenate and stannate from the excess of soda. The stannate is only satisfactorily precipitated in the presence of a sufficient quantity of arsenate, and additional arsenate may therefore be added if necessary to secure that the ratio of arsenic to tin in the solution is at least 3 : 1. The mixed arsenate and stannate crystals are dissolved in water and treated with calcium carbonate to precipitate calcium stannate and then with lime to precipitate calcium arsenate, and finally with more lime to caustify the soda; or the solution may be treated first with enough lime to precipitate the stannate, and then with enough lime to precipitate the arsenate; or the solution may be treated with excess of lime to precipitate the stannate and arsenate together, the tin and arsenic being then separated by known ways; or the solution may be treated with alkali bicarbonate or carbon dioxide which precipitates tin oxide leaving sodium arsenate in solution; or the solution after separation of the tin may be treated to obtain other arsenates. According to the Provisional Specification lead arsenate may be obtained by treating the arsenate solution with lead nitrate, the sodium nitrate being recovered for use in the lead refining process; when the calcium stannate and arsenate are produced together the mixture may be heated with carbon in a current of air to separate arsenious oxide as a fume; and the sodium antimonate produced in the first operation may be treated with nitric acid to obtain antimony oxide and sodium nitrate.
