  The leaching and adsorption operation used a leaching and adsorption system composed of a double-impeller leaching agitation tank. The first tank was the leaching tank, and the second to the sixth tanks were the leaching adsorption tanks. The leaching reagent was added to the leaching tank and stirred for leaching. The activated carbon was added from the sixth tank, and the activated carbon was transferred counter currently through the air lifter for adsorption. Each leaching tank was equipped with a carbon screen, the gold-loaded carbon was lifted from the second tank to the carbon-lifting screen by an air lifter, the slurry under the screen returned to the agitation tank, and the gold-loaded carbon entered the desorption electrolysis and carbon regeneration operations.

  The gold-loaded carbon lifted from the leaching adsorption system was fed into the desorption electrolysis system. The activated carbon can continue to be used after acid cleaning regeneration by stirring in the acid cleaning tank and thermal regeneration in activated carbon thermal regeneration furnace to restore activity.
