sart process of copper and gold

SART Process for Gold Recovery and Cyanide Management : BQE ...

Our Technologies to Treat Cyanide/SART. 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...
