Gold Leaching Cyanide Decontamination Gold Cyanidation

A VPSA oxygen system is the best way to introduce oxygen into gold slurry leaching and cyanide decontamination systems. The use ofpounds instead of air as an oxidant increases the leach rate and decreases cyanide consumption. This increase in the dissolved oxygen level of gold bearing slurry enhances the gold cyanidation process, thereby increasing gold recovery rates.

The cyanide solution strength is also important in leaching gold, with the typical range of solution being in the 0.02 0.05 NaCN. The gold particle size has a tremendous effect on the time required for dissolution in a cyanide solution. Generally, the finer the gold, the quicker it will dissolve. A 45 micron particle of gold would dissolve in 10 13 hours, while a 150 micron particle might
