FIELD: chemical technology. SUBSTANCE: method is carried out by precipitation of copper arsenates from arsenic-containing solution with alkali following by treatment of suspension with alkali and then - with acid. Arsenic-containing solutions are treated with alkali before copper arsenates precipitation. Then alkali is added to suspension additionally (0,004-0,133 g/g product) and neutralized its with acid. Suspension is filtered, and copper arsenates are separated. Output of filtration is 13,5-48,8 kg/13.5-48.8 kg/m2·h h. EFFECT: improved method of production. 2 tbl
