a flow sheet of autoclave leaching of gold

  • High Pressure Acid Leach Caldera Engineering

    This hot slurry is pumped into an autoclave (a giant pressure cooker of sorts) where acid is added. The slurry and acid then react as they flow through several compartments within the autoclave. The slurry takes approximately 60 minutes to complete the leaching process in the autoclave.
