1393606 Zinc sulphate purification SOC DES MINES ET FONDERIES DE ZINC DE LA VIEILLE MONTAGNE SA 27 July 1972 [16 May 1972] 35144/72 Heading C1A [Also in Division C7] Zinc sulphate solution is purified by: (1) coprecipitating hydrolysable impurities with Fe(OH) 3 ; (2) adding zinc to remove Cu and Cd by cementation; (3) heating to between 80‹ C. and the boiling point; and (4) adding antimony or an antimony compound and zinc powder to cement Co. The preferred antimony compound is Sb 2 O 3 and the zinc powder may contain 0À5-2% by weight of lead. A lead salt (preferably lead sulphate) may be added with the antimony compound or before the zinc powder. Zinc may be produced from the purified solution by electrolysis.
