  • Day 51 Procedures to obtain gold Vat Leaching Process

    The footprint of a vat plant is much smaller than that of a dedicated heap-leach operation even when considering disposal of vat tailings. A smaller treatment area also leads to plant simplicity and reduced cost of material transport. The main disadvantage to vat leaching is higher capital and operating costs than heap leach operations.

  • How to reduce mining costs while increasing productivity

    Dec 18 2017 · In the recovery of gold a cyanide solution is evenly distributed across the top of the heap. The common problem is the flow of the solution quickly slows due to the ore s natural composition. This creates a long and extended leaching process adding to operating costs and reducing the amount of gold recovered.

    KEY The gold ore is "above ground" meaning no more mining risk or cost. Our rule-of-thumb is that mining costs are half the operating cost per ton to reach unrefined gold bar from a property. In order to optimize leaching it is already known that the dynamited ore from open pits would need to be further crushed as it was not before.
