CYANIDE RECOVERY COST EFFECTIVENESS IS WHY

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
