Cyanide Leaching Of Gold - Mine Engineer.Com

2013-1-3  Much thought and design goes into the making of a heap leach, to derive the best, most economical solution for recovering the gold from the ore. Once the gold has been dissolved in the cyanide, and the ore body has been reasonably depleted of its gold, there are two main processes for recovering the gold from the pregnant cyanide solution.

The Metallurgy of Cyanide Gold Leaching – An

2014-10-20  Nature of Gold: The surface of a gold particle will typically be dissolved at a rate of around 0.2-0.5 µm of surface depth per hour in a cyanide leach. For large gold particles and nuggets, this is too slow to be fully dissolved in a typical processing plant. Much simpler and less expensive gravity methods are available to recover this gold.
