A VPSA oxygen system is the best way to introduce oxygen into gold slurry leaching and cyanide decontamination systems. The use of oxygen compounds 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.Онлайн-запрос

Cyanide leaching of gold is carried out in very large mechanically stirred tank reactors. The reactor size can be up to 5000 m3. A typical agitator configuration is two downward-pumping hydrofoil impellers, which requires a low mixing power input and results in low shear rates inside the reactor. This results in an economically efficient process with low levels of carbon attrition, to thusОнлайн-запрос
systems that use cyclones only or cyclones and high-rate thickeners can also be used in principle. Leaching reagents in the form of cyanide and an oxidant such as air or oxygen are added after thickening. Leaching takes place in a series of agitated leach reactors or pachucas. Before leaching the pH of the pulp is normally adjusted to a value of around 9.5–11 to ensure minimum loss of
