08-06-2016· The gold cyanidation process is the most important method ever developed for extracting gold from its ores. The reasons the widespread acceptance of cyanidation are economic as well as metallurgical. It usually obtains a higher recovery of gold than plate amalgamation and is easier to operate than the chlorine or bromine process.
01-01-2016· In the case of cyanidation plants processing gold ores with metallic sulfides, oxygen is not only used to optimize plant throughput but also to enhance gold extraction. Because the dissolution of sulfide minerals consumes oxygen ( (26.8), (26.10), (26.11) ), it is important to avoid a reduction in the gold-leaching rate associated with low DO in the pulp.
