Bioleaching. Some bacteria can live by using the energy of the bond between sulfur and copper. This separates the metal from the ore and is called bioleaching. It has the advantage that it is very energy efficient typically using only 30% to 50 % of the traditional method. It has the disadvantage that it is very slow. Phytomining.
