2021-1-17  extraction of specific metals from their ores using bacteria. Certain bacteria can break down low-grade ores to produce an acidic solution containing copper ions. The solution is called a leachate and the process is called bioleaching. Iron is more reactive than copper. It can displace copper from the leachate.
