Oct 20, 2014· 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.
Many opportunities exist throughout the world for small cyanide plants, possibly using a Gold Leaching Process, both for production and pilot operations, especially in areas not easily accessible, and where labor and local costs are on a level for profitable operation. Ores not fully amenable to treatment by amalgamation or flotation processes for the recovery of gold and silver can often be ...
