Inquire nowNature 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.
Inquire nowGold recovery can become uneconomical when cyanide-soluble base metals such as copper and zinc are present in gold ore deposits. These metals form weak acid dissociable (WAD) complexes with the cyanide and preferentially
