Solvent Extraction and Electrowinning | Mining | SGS

SX-EW (solvent extraction and electrowinning) are distinct metallurgical unit operations that recover high purity metal from leachate solutions. Solvent extraction is used to concentrate materials in an organic solution, while electrowinning is used to recover these pay elements. The two procedures are often conducted together.

Water Consumption at Copper Mines in Arizona

Copper minerals generally occur as oxides or sulfides. These require different treatments for extraction of the metal. The oxides are exposed to acid in a heap leach; this liberates the copper ions and the resulting solution is then sent to the solvent extraction (SX) process followed by electrowinning (EW) of the copper.
