Inasmuch as gold-silver alloys of this composition are almost as soluble in cyanide as gold is, it is probable that some other factor has affected the solubility of the electrum particles. Possibly some other alloying element has influenced their solubility in cyanide. The only compounds of gold found in nature are the gold-silver tellurides.

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 ...
