  • Basics of Cobalt Electrowinning in Under 3 Minutes

    3) Temperature and pH. Cobalt is a metal that can be a bit picky when it comes to conditions in which it will electrowin. It doesn't like being too hot, or too cold, and it definitely doesn't like being at the wrong pH. Cobalt prefers a temperature range of 40-600C and a pH of below 2 or greater than 4. These three parameters are not full ...
