A process used to extract metals from their ores by using electricity to deposit the metal onto an electrode from a solution.
Electrowinning is commonly used in the mining industry to recover gold and copper from their solutions.
Electrowinning is formed from "electro-" (from Greek "ēlektron", meaning amber or electricity) and "winning" (from Old English "winnan", meaning to strive or gain). The term describes the process of gaining or extracting metals from their ores using electricity.
Think of 'electricity' ('electro-') being used to 'gain' ('winning') metals from ores — that's what electrowinning means.
