Chloride hydrometallurgical process for production of copper |
摘要 |
A process for extractive metallurgy of metal sulfides, in particular copper sulfide ores, in which a metal sulfide mineral feed material is cocurrently oxidized in an aqueous cupric chloride solution in the presence of an oxidant to form a slurry containing a metal hydroxide precipitate; the slurry is leached with an acid; the leach solution is extracted with an organic extractant; the organic extractant is stripped with an aqueous stripping medium; and the copper is electrowon from the aqueous stripping medium. The large amount of acid required for the oxidation reaction is provided by the formation of the metal hydroxide precipitate.
