  • Bioleaching

    2018 10 30ensp;0183;ensp;Bioleaching is the extraction of metals from their ores through the use of living organisms.This 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

  • The bioleaching of sulphide minerals with emphasis

    The most successful copper heap leaching operations have been those processing copper oxides and secondary copper sulphides ().Chalcocite (Cu 2 S) is the main copper sulphide mineral mined at bioleaching operations. Some of the chalcocite heap operations began as oxide (chemical) leach operations and were converted to bioleach (oxidative) operations by heap aeration and/or inoculation,
