SART Process for Gold Recovery and Cyanide Management : …

Gold 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 competes for cyanide. The result is high cyanide consumption, poor gold doré purity and high concentrations of copper ...
