A new way of extracting copper

28 06 2017  Contrary to aluminum however there are no direct electrolytic decomposition processes for copper containing sulfide minerals to produce liquid copper The MIT researchers found a promising method of forming liquid copper metal and sulfur gas in their cell from an electrolyte composed of barium sulfide lanthanum sulfide and copper sulfide which yields greater than 99.9 percent pure copper.
