Abstract

16,931. Raschen, J., Wareing, A. E., and United Alkali Co. Aug. 21. Arsenious acid; sulphuric acid. - Arsenical sulphur ores are burnt and the gaseous products are passed into a tower down which sulphuric acid flows. The sulphuric acid is then freed from the dissolved arsenious oxide by treatment with hydrochloric acid gas preferably in a tower. The liquid arsenious chloride formed is separated from the acid, and is then treated with a limited amount of water containing an alkali or alkaline earth or carbonates of these substances or raw materials containing the above or mixtures of them. Arsenious acid precipitates, and may be purified, if desired, by sublimation.
