Cyanide Use in Gold Mining Earthworks

Heap leaching In the open, cyanide solution is sprayed over huge heaps of crushed ore spread atop giant collection pads. The cyanide dissolves the gold from the ore into the solution as it trickles through the heap. The pad collects the now metal-impregnated solution which is stripped of gold and resprayed on the heap until the ore is depleted. Vat (or tank) leaching The ore is mixed with

Heap leaching is used extensively for the processing of copper and gold ores. Low capital and operating costs and simple atmospheric leach processes make heap leaching suitable for low- grade ores and small deposits. Disadvantages include low recoveries, long ramp-up times, large footprint and acid-mine drainage of wastes3. Factors that may make ores unsuitable for heap leaching are poor

Leaching Mining Fundamentals

Heap leaching is also known as acid leaching. This method is most effective for the extraction of metals from difficult ores, and is one of the most tried and tested methods. The pre-processing of ore before leaching involves the grinding and roasting of the ore. Roasting is done to remove the carbonaceous elements trapped inside the ore. After pre-processing, the ore is leached with acid of
