The mining method typically extracts the ore in 30-50m panels separated by 5-10m rib pillars which remain in-situ to provide geo-mechanical stability and support. For ore structures that dip between 25.0 degrees and 35.0 degrees the ore is extracted using manual mining techniques (air-leg mining) to optimise recovery and reduce costs.

Estimating process design gold extraction, leach …

 · 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 cyanide …
