Solution mining followed by solvent extraction-electrowinning (SX-EW) is one possible way to economically extract copper from ore bodies which cannot otherwise be profitably exploited. Published costs for the unit processes of SX and EW are out of date especially in view of the newer reagents now available and the newer circuit configurations.

An alternative to recycling the bleed is to electrowin the copper from the bleed; this low copper, high acid solution can then be sent to the raffinate (A) for higher leach recovery, or (if the acid concentration is not too high – 180-200 g/L) to stripping (D) for higher SX recovery.When the decopperized bleed solution after emew copper recovery …

Pumped water may be used in extraction and beneficiation activities (including dust control), pumped to tailings impoundments, or discharged as a waste through an NPDES permit. Because mine water at copper mines is often rich in dissolved copper and other metal ions, some operations pump it to an SX/EW plant to recover the copper values ...

The history of US SX-EW is somewhat different. Initial production of SX-EW copper was minimal, and stayed that way until incremental improvements allowed for the bypassing of end refining. Up until that time, Chilean SX-EW copper. A comparison to the Chilean copper industry (the United States' biggest competitor in copper) is instructive.

The copper Leaching, Solvent Extraction and Electrowinning circuit (LX–SX–EW) is one of the most effective processes for extracting copper from low grade ores. This work focuses on the liquid–liquid extraction SX sub-process, since many difficult to handle operational problems within LX–SX–EW circuits are related to SX malfunction.
