Abstract

The disclosed invention concerns a process comprising: (a) providing a pregnant leach solution comprising copper values; (b) contacting the pregnant leach solution with an organic phase comprising a copper extractant at an extraction temperature, Text, to form a loaded organic phase comprising the metal values; (c) contacting the loaded organic phase with an aqueous stripping solution at a stripping temperature, Tstrip, to form a copper-enriched stripping solution; wherein the difference in temperature ( T) between the stripping temperature and the extraction temperature according to equation (I): T = Tstrip - Text is less than or equal to about 10 C. In other increasingly more preferred embodiments of the invention, the difference in temperature ( T) is less than or equal to about 5 C, less than or equal to about 2.5 C, less than or equal to about 0 C, less than or equal to about -5 C, and less than or equal to about -10 C. Also disclosed are economic means to manipulate th e extraction, strip, and electro winning temperatures to achieve these temperature differentials.
