Basics of Cobalt Electrowinning in Under 3 Minutes
2021-10-26 · Cobalt is one of few metals that can be electrowon relatively easily, however, it does not come without its challenges. Cobalt has a more negative reduction potential than nickel, copper, silver and gold which means that solutions must be free of these impurities prior to electrowinning of cobalt.
