Cyanide Leaching Of Gold Mine

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.
