Direct sulfide electrolysis extracts metal using less energy

In comparison, aluminum is typically extracted from its oxide ore alumina using electrolysis, which involves passing electric current through a molten alumina solution. But electrolysis does not work with sulfide compounds. “Metal sulfides have an intolerably high electronic conductivity so they consume electricity without producing metal,” says Donald Sadoway, a materials chemist at MIT.
