    Bioleaching and phytomining are increasingly used to extract copper from low grade ores (see below). The traditional method of extraction is to heat the copper sulfide. Copper (II) sulfide gives copper and sulfur dioxide during

  • Reactivity and extraction method

    Phytomining, bioleaching and scrap iron Some plants absorb copper compounds through their roots. They concentrate these compounds as a result of this. The plants can be burned to produce an ash that contains the copper compounds. This method of extraction is called phytomining. Some bacteria absorb copper compounds.
