Abstract

Procedure for the precipitation and separation of arsenic from the arsenous and cuprous solutions, which in each case may contain further non-ferrous metals, by wet metallurgical route, characterized in that the solution, provided that the ions contained therein are no longer present in the maximum valence stage, are treated with oxidation agents until reaching this state under maintenance of a ph <= 1, an amount of iron greater than the stoichiometric in proportion to the arsenic in the form of an acid soluble iron salt is added and dissolved, if necessary further oxidized, then by the addition of alkali, preferably lime, is adjusted to a ph of 1.9 - 2.0 in solutions containing chlorine, or 2.7 - 2.8 in purely sulfate solutions, the precipitated mixture composed of iron arsenate, excess iron hydroxide, if any, gypsum and residues insoluble in acid of the material used, they are separated from the mother liquor and, in a known manner, they are made with copper and, if necessary, with other metals that still exist.
