  • Bioleaching

    Bioleaching is the extraction of metals from their ores through the use of living organismsThis is much cleaner than the traditional heap leaching using cyanide Bioleaching is one of several applications within biohydrometallurgy and several methods are used to recover copper, zinc, lead, arsenic, antimony, nickel, molybdenum, gold, silver, and cobalt...

  • Phytoremediation

  • Phytomining of gold: A review

    Phytomining involves the use of hyperaccumulating plants to extract valuable metals from the substrate Hyperaccumulating plants occur naturally for many metals such as nickel, cadmium and manganese etc, where most of the metals are bio-available in soil solution for plant uptake ( Baker and Brooks, 1989 )...
