1. an industrial process in which metal is extracted from a solution by passing an electric current through it, causing the metal to deposit on a cathode.
Usage: technical; metallurgy

Examples

• Electrowinning is commonly used to recover copper from ore solutions.
• The electrowinning process requires careful control of voltage and current.
• Gold can be extracted from solution using electrowinning techniques.
• Modern electrowinning plants use advanced cathode materials to improve efficiency.
• The company invested in electrowinning equipment to process their mineral concentrates.
• Electrowinning produces high-purity metals compared to traditional smelting methods.
