Abstract

Procedure for the precipitation and separation of arsenic from solutions containing copper, which may contain further non-ferrous metals, by wet metallurgy, where the solution, provided that the ions contained therein are not already in the valence stage maximum, they are treated with oxidation agents until reaching this state under maintenance of a ph <= 1, an amount of iron higher than the stoichiometric one is added with respect to arsenic, in the form of an iron salt soluble in acid and dissolves, if necessary, it is further oxidized, by raising the ph by addition of alkali, preferably lime, a mixture of iron arsenate and excess iron hydroxide is precipitated, as well as, if appropriate, gypsum, and this precipitated product is separated together with the acid-insoluble starting material residues of the mother liquor and this is prepared in a known manner for obtaining copper and other metals even xisting, characterized in that the ph value of precipitation in the chloride-containing solutions is adjusted to 2.0 to 2.5, preferably 2.2 to 2.3, and, in purely sulphatic solutions to 2.8 to 3.2, preferably 2.9 to 3.0.
