Extractive Metallurgy of Copper | ScienceDirect
The SX process consists of extracting Cu 2+ from aqueous PLS into a copper specific organic extractant, separating the aqueous and organic phases by gravity, and then stripping Cu 2+ from the organic extractant into highH 2 SO 4 electrolyte returned from the EW circuit. The process is continuous and is carried out in large Mixersettlers.
