Abstract
In the separation of arsenic, with or without selenium, from acids such as concentrated sulphuric acid by precipitation as sulphide, the separation of the precipitate is assisted by the presence in the acid of inert solid substances such as finely divided sand or alumina, of gases such as nitrogen, hydrogen, oxygen, or air, or of liquid organic substances such as benzene in conjunction with a frothing agent such as pine oil or oil of turpentine. Mixtures of solids or of gases may be used or solid and gaseous substances may be used in succession, and when hydrogen and oxygen are used, they may be prepared in situ by electrolysis. In carrying out the process, the assisting substances may be stirred into the solution prior to, during, or after precipitation of the sulphide, and stirring be continued after precipitation; after stirring is suspended, the precipitate settles with the solid when used, or rises to the surface as a scum when a gas is employed, or separates on the surface with the liquid and frothing agent when these are used. Specification 349,472 is referred to.
