Abstract
Zinc solutions, such as zinc sulphate, are purified for electrolysis by treatment with ozonized air in presence of a metallic oxide, hydrate, or carbonate, manganese dioxide, manganese hydrate, lead and zinc oxides and carbonates, and zinc hydrate being mentioned as suitable. The treatment is preferably effected at a raised temperature and with agitation. If the zinc solution contains manganese, an added reagent is not necessary, and the manganese compound may be caused to precipitate by adding a reagent such as chalk or zinc oxide. Any manganese remaining in the solution after purification is recovered as peroxide mixed with lead peroxide as an anode mud in the electrolysis, and this mixture may be used as the catalyst. The treatment described removes iron, cobalt, arsenic, and antimony; but copper, nickel, and cadmium are not completely precipitated. These metals are finally removed by treatment with zinc dust as described in Specification 138,947, or with zinc dust in presence of acid, as described in Specification 138,954.
