arsenic gold leaching

  • Bioleaching - Wikipedia

    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…
