Merrill Crowe in Leaching Gold / Silver Processing
Gravity Recovery & Au/Ag Leaching – CCD Merrill Crowe Plant & Refinery: This complete hydrometallurgical process plant is for recovering precious metal from oxide or very low sulphide ore deposits containing silver and/or gold more commonly. The turnkey plant is for the recovery by cyanidation leaching from ores absent of preg-robbing carbonaceous material. The initial gravity circuit will extract any coarse, slow leaching gold and silver. The simple Merrill-Crowe technology best deals with high 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, counter-current decantation circuit, Merrill-Crowe precipitation and 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.
