Gravity Recovery and Leaching of Gold & Silver – CIL Stripping & Refinery: This complete hydrometallurgical process plant is to recover silver and/or gold metals from oxide or very low sulphide ore deposits. Provided here are all major equipment for a plant arranged to recover dissolved precious metals using the Carbon-in-Leach process. CIL with activated carbon is best suited for ores with no or some levels of preg-robbing carbonaceous material. The initial gravity circuit will extract any coarse, slow dissolving GRG gold and silver. The simple CIL technology deals best with low grade gold and/or silver deposits.
This simple metallurgical concentrator includes single stage crushing, conveying, primary grinding, spiral classification, gravity concentration, slurry pumping, cyanide leaching tanks, loaded carbon stripping and regeneration as well as refinery.
With this simple flowsheet, you will recover silver and/or gold into a bullion bar.
The gravity recovery components of this circuit can easily be removed in cases where laboratory testing has revealed there are no GRG precious metals in your ore.
Our standard packages are for process plants of:
- 25 Tonnes/Day = 1 Tonne/Hour
- 50 Tonnes/Day = 2 Tonne/Hour
- 100 Tonnes/Day = 4 Tonne/Hour
- 250 Tonnes/Day = 10 Tonne/Hour
This is a standard process plant which includes only the major components of the complete metallurgical flowsheet. A detailed engineering study is required to identify unforeseen omissions that may be required to design the optimum plant.
Additionally, we offer two separate packages for plant tailings thickening/filtration and water treatment. Contact us for details.
