##tihuan2##In leaching, ore which has been ground to pulp is placed in agitated tanks with sodium cyanide solution and gold and silver is dissolved into the slurry solution. The leach may require 24 to 72 hours to complete, and after the leach is completed, the leached slurry is routed to the CIP circuit.

##tihuan2##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).

##tihuan2##Carbon-in-pulp (CIP) and carbon-in-leach (CIL) circuits have been the primary methods used for treating gold ores for many years. Although inherently robust processes, there is still often much room for optimisation to improve gold extraction efficiencies and to reduce reagent consumption and operating costs.

##tihuan2##The well-known carbon-in-pulp (CIP) and carbon-in-leach (CIL) gold recovery processes are fairly robust. Considering the constantly changing characteristics of run-of-mine (ROM) ore, a robust process is in general a great advantage for a mineral processing plant. The disadvantage, however, is that because less input is required from operators and
