  • Gold ore Carbon-In-Leaching (CIL) processing technology

    The flotation tailings containing the unrecovered gold from the primary circuits are directed to the leaching plant and dissolved in an aerated sodium cyanide solution. The solubilized gold is simultaneously adsorbed onto coarse granules of activated carbon directly in the pulp in the so-called Carbon-In-Leach process (CIL).

  • Gold CIL & CIP Gold Leaching Process Explained CCD

    02-01-2013· Cyanide is a lixiviant, or reagent that is used to leach, often in tanks, gold from a solid matrix and form a gold cyanide complex. The gold cyanide complex is then extracted from the pulp or slurry by adsorption onto activated carbon. CIL stands for carbon-in-leach. This is a gold extraction process called cyanidation where carbon is added to the
