The reactions that take place during the dissolution ofgoldincyanidesolutions under normal conditions have been fairly definitely established. Most agree that the overallcyanideequation forleachingand cyanidation ofgoldis as follows: 4 Au + 8 NaCN + O2 + 2 H20 = 4 NaAu(CN)2 + 4 NaOH

Most cyanide leaching is carried out at a alkaline pH of between 10 and 11, depending upon lab testing of individual ores and the optimum leaching/chemical use rates. The cyanide solution strength is also important in leaching gold, with the typical range of solution being in the 0.02% -0.05% NaCN. Thegold particle sizehas a tremendous effect on the time required for dissolution in a cyanide solution. …

Heap leaching: In the open, cyanide solution is sprayed over huge heaps of crushed ore spread atop giant collection pads. The cyanide dissolves thegold 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.

Thecyanide leachingof tellurides has a history of controversy, with some researchers maintaining that successfulgold extractioncould be achieved provided that certain conditions were met. Operationally, plantleachingproved to be not as successful as in the laboratory and certainly was not as robust as theleachingof freegold.
