FIELD: inorganic chemistry. SUBSTANCE: copper hydroxide is made by hydrolytic decomposition of copper arsenates with alkaline solutions at 0-50 C following by separation of copper hydroxide. Copper arsenates are used as products of arsenic-containing effluences reprocessing in copper production. Anionized effluences of copper-molybdenum concentration plant are used as a source of alkaline solutions. EFFECT: improved method of copper hydroxide production. 3 cl, 3 tbl
