Solvent extraction and electrowinning - Wikipedia

Solvent extraction and electrowinning (SX/EW) is a two-stage hydrometallurgical process that first extracts and upgrades copper ions from low-grade leach solutions into a solvent containing a chemical that selectively reacts with and binds the copper in the solvent.

Innovations: Introduction to Copper: Mining & Extraction

Today, more than 13% of all "new" copper is produced from leachates, which are normally concentrated using solvent extraction (SX) and stripped of their copper content by conventional electrowinning (EW), the so-called SXEW process.

Copper & Nickel Solvent Extraction

Because fresh solvent was used for the 12-vol-pct test, the solvent was contacted with the copper electrolyte prior to the run to establish the equilibrium copper level in the solvent. The selected flow rates resulted in an average extraction mixer residence time of 5.3 minutes per stage and an average nickel strip mixer residence time of 7.1 ...

SX Solvent Extraction Process Principles Theory

A high copper/nickel ratio on the copper loaded organic is obtained by using an extra extraction stage in which copper crowds nickel from the loaded organic, i.e., the copper in an ammoniacal copper and nickel containing solution, when contacted with an organic loaded with nickel, will replace some of the loaded nickel.
