extraction of lead from low grade ore

  • innovations in copper: mining & extraction: producing

    as indicated above, bioleaching originated by the leaching of low grade ore dumps, flotation tailings and other waste materials already in place. as the technology has progressed it has moved to more processing amenable methods: i.e., leaching on a controlled leach pad (heap leaching) (see the phelps dodge mine for leach project)
