Definitions for "Electrowinning"
(2) recovery of a metal from an ore or solution by electrochemical processes.
An electrochemical process used to recover gold and other metals from solution in the leaching of ores and concentrates.
A common metal recovery technology. Essentially electroplating, electrowinning is iployed to electrolytically recover metal from wastewater through electrolysis. Large cathodes, and other design strategies are iployed to win metal ions from dilute waste streams. Metal is recovered on cathodes for reuse or sold as scrap. The most common application is on drag-out tanks, where the fluid is continuously recycled through the electrowinner and a low concentration of metal is maintained (rather than the steadily rising concentration that would otherwise occur in a still rinse).
