Gold Heap Leaching Practices

Activated carbon has the ability to adsorb the NaAu(CH)2 ion onto its surface. With typical pregnant gold values being 1.0 g/t (0.03 oz/st) and barren solution gold values running between 0.14 and 0.34 g/t (0.004 to 0.010 oz/st) it means 75% of the gold is normally adsorbed by the carbon on a single 7 minute journey through the five towers.
