The Metallurgy of Cyanide Gold Leaching – An Introduction ...

Leaching gold with a cyanide solution remains the most widely used hydrometallurgical process for the extraction of gold from ores and concentrates. Despite the difficulties and hazards of working with cyanide, no other process has yet been proven to be an economic viable alternative. A paper published by L. Elsner in 1846 first correctly identified the chemical reaction that forms the basis ...

Modelling and simulation of gold ore leaching

Gold leaching model The dissolution model is based on the basic electrochemical and diffusion mechanisms proposed by Habashi8. It is modified to account for possible loss of oxygen efficiency, as proposed by Rubisov et al.9 who used a stoichiometric factor representing the number of moles of leached gold per moles of oxygen consumed, assuming that oxygen is consumed by an intermediate

Cyanide Leaching Of Gold - Mine Engineer.Com

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 ...

Improving the process performance of gold cyanide leaching ...

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 thus ...

Heap Mining Efficiently Leaches Lower Grade Gold from S

How Does Heap Leaching Process Work? Gold ores that are near surface are often oxidized by nature and can be leached within 1 or 2 months. The oxidation process is usually caused by exposure to water sometime in the sedimentary process of the earth’s surface. For instance, Nevada was a large lake millions of years ago, so you see a lot of oxidized gold there. Oxidation is nature’s way of ...
