what is phytomining and how does it work

BBC - GCSE Bitesize: The future of copper

This method of extraction is called phytomining. Some bacteria absorb copper compounds. They then produce solutions called leachates, which contain copper compounds. This method of extraction is called bioleaching. Copper can also be extracted from solutions of copper salts using scrap iron. Iron is more reactive than...
