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 cyanide and

CYANIDE RECOVERY COST EFFECTIVENESS IS WHY RECYCLE

cyanide destruction and cyanide recovery costs for a fairly generic high cyanide consuming case. The capital cost of a cyanide recovery plant could pay back in less than 2 years in many cases, particularly when high cyanide consumption is associated with copper mineralisation in the ore. As a broad generalisation, cyanide recovery
