The process can take 24–60 h of cyanidation, depending on the intensity of agitation and aeration of the tanks. Once the gold is dissolved in the cyanide solution, two techniques are commonly used to recover it: (1) adsorption of gold onto activated charcoal, or (2) gold precipitation with zinc. Fig. 2.

South Deep's gold plant has the capacity to process around 330,000 tonnes of ore per month and the capability to treat more underground ore than most other plants in the Far West Rand Region of South Africa.
