Abstract

262,546. Mackay, H. S. Sept. 24, 1925. Copper, obtaining from ores containing coppe: and zinc. A solution of copper and zinc sul phates is obtained and copper deposited there from by electrolysis until the concentration o copper sulphate is low relative to that of zinc sulphate; the zinc sulphate is then crystallized out by evaporation. In the plant shown, the ore is roasted in a furnace A and the residues or concentrates delivered bv a conveyer B to tanks F where they are leached with dilute sulphuric acid. Tanks G. H are provided to receive solutions of low acid content and of higher acid content respectively from the tanks F, the two solutions being used in the manner described in Specification 238,962. The product is passed to an agitator I where iron, aluminium, and other impurities are precipitated, and the solution is then passed through a filter press K to a bank L from which it passes to electrolytic cells M. The spent electrolyte is passed to an evaporating plant 11 heated by the products of combustion from the furnace A and when saturation point is reached is passed to crystallizing tanks 12. The solution from the tanks 12 is returned either to the evaporator or to the tank L. A line 15 is provided to return free sulphuric acid from the cells 11 to the tanks L, H whenever necessary for standardization. The crystallized zinc sulphate is passed to a tower 17 where it is redissolved and treated with calcium carbonate or zinc dust to precipitate copper present as impurity. The solution is decanted or passed by a filter press 18 to a storage tank 19. When calcium carbonate is used as precipitating agent, the copper hydrate is passed to the tower I and used for precipitating iron and aluminium. When zinc dust is used as precipitating agent, the precipitated copper is returned to the furnace A. The pure zinc sulphate solution is passed to an evaporator 22 or electrolyzed to deposit zinc. Specifications 26138/13 and 205,528, [Class 82 (i), Metals, Extracting- &c.], are referred to in the first Provisional Specification.
