Abstract
11,634. Hunt, E. J., and Gidden, W. T. May 19. Zinc and lead peroxides, obtaining. - In the deposition of zinc from a solution of the sulphate and sulphuric acid, with the use of a leaden anode, a device such as an asbestoscloth diaphragm, or a porous covering on one of the electrodes, is employed for preventing access of suspended lead compounds, such as the peroxide and sulphate, to the cathode, while allowing circulation so that the electrolyte has practically the same composition at anode and cathode. If necessary, the strength of the electrolyte near the cathode is kept up by addition of free acid, which may be obtained from the anode liquid. Pure zinc, unattacked by the acid in the electrolyte, is obtained. The lead peroxide produced may be used for preliminary purification of the electrolyte from iron and manganese, preferably with the aid of heat; the precipitation may be completed by the addition of alkali, zinc or other metallic oxide, zinc, calcium, or other carbonate, or metallic zinc. Crude zinc oxide or carbonate may be dissolved by acid liquid withdrawn from the cell, the lead peroxide being either left in the liquid, or separated before lixiviation and added afterwards. The Provisional Specification states that lead peroxide from other sources may be used for purifying the electrolyte.
