The leaching and adsorption behaviour of gold ores

Kinetic models were developed for the leaching of gold from the ore, adsorption onto activated carbon and preg robbing at the ore surface. A variable order empirical model of the Mintek form was used to describe leaching, while adsorption was modelled using the film transfer model. A model of this form was also used for preg­ robbing using thendlich isotherm to describe the equilibrium

Processing Gold Ores Using Heap Leach Carbon Adsorption

Although activated carbon has been used in gold silver recovery from cyanide solutions for several decades, the mechanism of gold adsorption on activated carbon is still not fully understood. One theory is that the gold is adsorbed as the goldplex AUCN~ and that this adsorption takes place by ion exchange 1, p. 341.

Gold extraction

A refractory gold ore is an ore that has ultra fine gold particles disseminated throughout its gold occluded minerals. These ores are naturally resistant to recovery by standard cyanidation and carbon adsorption processes. These refractory ores require pre treatment in order for cyanidation to be effective in recovery of the gold. A refractory ore generally contains sulfide minerals, organic

Carbon Adsorption In Recovery Of Gold Mine

The carbon in pulp method is only used where tank leaching is utilized for the recovery of gold from the ores and this is not the case in most large gold mines today, since heap leaching is the lowest cost method for recovering gold from ores containing from a few grams to 5 or 6 grams per ton. If the ore is a high grade, it may be feasible to tank leach it. By high grade, it would probably be

Factors influencing the rate of gold cyanide leaching and

Carbon in leach CIL is slightly more difficult to simulate and model, since gold is leaching from the ore into solution at the same time as it is adsorbing onto the carbon, and the concentration of gold in solution in each stage which is still assumed to be at a constant steady state is a function of the relative rates of leaching and adsorption. The expression that has been derived to
