Gold and Silver Leaching Practices in the United States

(leaching). Basically gold and silver leaching involves spraying a cyanide so- lution on the ore to dissolve the metal values, collecting the solution contain- ing the dissolved metals, and recovering the metal from the solution. By elimi- nating milling, leaching reduces …

The Metallurgy of Cyanide Gold Leaching – An Introduction ...

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.

Estimating process design gold extraction, leach residence ...

Plant design parameters for gold extraction, leach residence time and cyanide consumption are generally determined from standard bench-scale bottle roll or agitation leach tests. The application of laboratory data to process design has essentially evolved from the testing of oxide or low cyanide-consuming ores. Such scale-up factors may not be appropriate for ores that deplete …
