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 solventInnovations: How Hydrometallurgy and the SX/EW - Copper,Beginning in the mid 1980s a new technology, commonly known as the leach-solvent extraction-electrowinning process or, SX/EW Process, was widely adopted This new copper technology utilizes smelter acid to produce copper from oxidized ores and mine wastes Today, worldwide, approximately 20% of all copper produced is produced by this is processElectrowinning - an overview | ScienceDirect Topics,The small investment requirement of leach/solvent extraction/ electrowinning plants is due to the small equipment and infrastructure requirements of these processes Specifically, leaching and solvent extraction require much less equipment than concentrating, smelting, converting, and anode casting
