Cyanide control in the metallurgical process of gold

AngloGold South Africa region currently consists of twelve gold plants. These plants use a combined total of $20 million of cyanide per annum. Of this, the major portion (60%) is consumed at two Ergo dump retreatment plants. Historically the primary motivation for cyanide control at Ergo has been one of leach/cost optimization.

Control of pH in the cyanide leaching process June 2015

If the gold exists in a larger, more concentrated state, the ore will be finely ground and leached in a tank. A gold cyanide complex will form as the gold dissolves from the rock or pulp (finely ground ore), according to the equation: 4Au + 8CN- + 2H 2 O +O 2 g 4Au(CN) 2 + 4OH. The control of pH in a cyanide leach solution is critical both from

May 01, 2011 But operating the plant at higher gold loadings slows the rate of adsorption of gold cyanide onto carbon and increases the gold losses in the barrens solution. This can be seen by comparing the profiles in Runs 2, 8 and 9, where the up-grading ratio was varied from 610 to 1000 to 1420, resulting in an increase in soluble gold losses from 0.001
