  • 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 high-H 2 SO 4 electrolyte returned from the EW circuit. The process is continuous and is carried out in large Mixer-settlers.

    May 17, 2000 · Projections are that a typical 50,000 ton-per-year copper electrowinning plant would see a payback in 18 months. One of the persistent and costly challenges associated with the SX/EW process for copper recovery is the build up of iron (Fe +3). Iron is leached along with copper from the ore and accumulates in the electrolyte circuit as the copper is removed in electrowinning.
