The gold ore at Pongkor and Cibaliung goes through various processes which include crushing, milling, cyanidation, carbon leaching and stripping, electro winning to melting and casting to produce bullion/ dore. The waste is processed at the detoxification plant to reduce the cyanide content of tailings to below the threshold limit value of 0.5,

Gold abundance in the Earth’s crust is 0.002 per 106 atoms of silicon [2]. Gold average economic abundance in the ore today is in the range of 0.1 to 0.2 oz/ton or 3.42-6.84 ppm, but deposits yielding grades to the fire assay which are as low as a tenth of those values are also exploited [2].
