The project contemplates a conventional open pit, operation with two-stage crushing. Crushed ore will be conveyed to the pad and irrigated with dilute cyanide solution. Gold will be recovered from pregnant solutions utilizing carbon adsorption, subsequent electrowinning and on-site smelting to produce gold and silver doré bars.read more
· Heap leaching: The ore is arranged in large heaps and treated as in slope leaching. 3. In-situ leaching: Water containing Thiobacillus is pumped through drilled passages to unextracted ore which remains in its original location in the earth. In most cases, the permeability of the rock must be first increased by subsurface blasting of the rock.read more
