Abstract
1488260 Hydrometallurgical copper production DUVAL CORP 31 Dec 1974 [14 Jan 1974] 56198/74 Heading ClA A hydrometallurgical process for the production of metallic copper in which there is provided a cyclic system capable of steady state operation, comprises an oxidation stage in which materials containing copper sulphide ore concentrates are oxidized in a solution containing ferric chloride and cupric chloride until there is substantial solubilization of the copper content of said materials in the form of cupric chloride, a reduction stage separate from the oxidation stage in which at least a substantial portion of the cupric chloride in the solution from the oxidation stage is reduced to cuprous chloride, an electrolysis stage in which metallic copper is recovered and cupric chloride is regenerated by electrolysis of the cuprous chloride solution from the reduction stage, and a regenerationpurge stage separate from the reduction and electrolysis stages in which the ferrous chloride in the solution from the electrolysis stage is reacted with oxygen in the presence of the regenerated cupric chloride to regenerate the ferric chloride required in the oxidation stage and to precipitate, by hydrolysis, compounds including those having the iron-sulphate ratios of jarosite to thereby remove excess iron as well as sulphate ions and other impurities present in the solution; wherein in said process the total chloride ion concentration is maintained at a level in the solution throughout the process by the addition of a saline metal chloride compound selected from potassium chloride, magnesium chloride, a mixture of magnesium chloride and potassium chloride, or a mixture of any of the foregoing with sodium chloride to maximize the degree of reduction of cupric chloride to cuprous chloride in the reduction stage with minimal loss of copper from solution. The available reactive chloride content may be controlled to allow some ferric chloride to remain in the solution to assure that all the reacted copper is present in solution as cupric chloride.
