Apr 27, 2017· Solvent extraction (SX) and electrowinning (EW), though chemically interdependent in an SX-EW plant, are two very distinct and physically separate unit processes. There are things that can be done in the SX circuit which will alter its capital cost but will not change the tankhouse and vice versa.

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. The copper is extracted from the solvent with strong aqueous acid which then deposits pure copper onto …

Copper extraction refers to the methods used to obtain copper from its ores.The conversion of copper consists of a series of physical and electrochemical processes. Methods have evolved and vary with country depending on the ore source, local environmental regulations, and other factors.. As in all mining operations, the ore must usually be beneficiated (concentrated).
