OPTIMIZING THE OPERATING CONDITIONS OF GOLD

2021-3-26  The final gold product of Tau Lekoa mine has a low fineness. This is caused by high concentration of bases metals in the reefs. Some of these base metals together with gold are leached with cyanide and are loaded into carbon. If not adequately controlled, they may elute with gold and contaminate the final product in the electrowinning process.

Factors affecting the elution of gold cyanide from ...

1994-1-1  Adams and Nicol [4] listed the most significant influences on elution, in order of decreasing importance, as follows : temperature, cyanide and hydroxide concentrations, and the ionic strength of the eluant. Likewise, Davidson [5] considered the temperature and reagent cyanide addition to be the most important factors affecting gold elution.

Elution In Gold Processing

The gold can then be removed from the solution by electrowinning onto steel wool cathodes (refer ‘Electrowinning and Smelting’ module). As well as stripping the gold from the carbon, the elution process incorporates an acid wash stage, which removes inorganic foulants from the carbon. Foulants reduce the activity, and hence gold adsorbing.
