The bacterial action creates acid solutions which leach heavy metals from the ore bodies as soluble sulfates. ... METAL ION REMOVAL Electrochemical technology is being increasingly applied to a wide variety of environmental and recycling problems (6-9). ... In practice, it is important to minimize secondary cathode reactions which commonly include hydrogen evolution from the electrolysis of water.
