Electrowinning
Electrowinning is a manufacturing process for making metals from a solution containing dissolved metal. The process involves passing an electrical current from an inert electrode through the solution containing the metal, to plate the metal to another electrode. Also called electroplating, it is a common process for producing metals like copper, cobalt, nickel, zinc, aluminum, and gold among others. Electrowinning is one of the last processes in metal production. It commonly follows leaching which is a process that dissolves minerals into a solution.
