A gold CIL processing plant designed for crushing, grinding, leaching, adsorption, tailings handling and gold-loaded carbon treatment. The process uses activated carbon adsorption and downstream desorption, electrolysis and melting to produce gold bars.

The plant uses activated carbon to adsorb aurocyanide and other complex ions from solution. Coarse carbon can then be separated from slurry by screening using wire mesh.
Raw ore is processed through primary, secondary and tertiary crushing with screening in a three-step one closed-circle flow. This prepares material for downstream grinding.
The process uses ball mills, a spiral classifier and a hydro cyclone in a two-step two closed-circle grinding arrangement. Oversize material is returned for re-grinding.
The slurry enters 8 sets of double impeller leaching tanks. Sodium cyanide is added to the first tank, while activated carbon is added from the second to the eighth tank.
Tailings are filtered by filter press, while filter liquor is sent to a circulating water tank for reuse. This helps reduce consumption of lime and sodium cyanide.
Gold-loaded carbon is treated by desorption and electrolysis equipment in batches to produce gold dust. The gold dust is then melted in a furnace to form gold bars.
