Solvent extraction and electrowinning - Wikipedia

From Wikipedia, the free encyclopedia 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.

Solvent extraction of copper from high concentration ...

Flowsheets that integrate PAL with solvent extraction (SX) for the downstream processing of autoclave discharge liquors present interesting opportunities for efficient metal recovery. Significant advances in copper SX have been made over the past thirty years [2], with almost 30% of world copper production today via this route.

Solvent extraction: the coordination chemistry behind ...

Solvent extraction processes to separate metalate anions on the basis of their charge are easier to implement in practice when the metals are kinetically inert because they do not lose coordinated anions to generate lower charged, more readily extractable species during the contact time in a mixer settler.

Solvent Extraction - an overview ScienceDirect Topics

Solvent extraction, also called liquid-liquid extraction, can be used to separate a solute from a solution by extraction into another solvent. The two solvents must be essentially immiscible. Solvent extraction can be used either to recover a valuable substance from the original solution, or to purify the original solvent by removing an unwanted component.
