Leaching of silver sulfide with ferricyanidecyanide

Significantly lower silver extraction than gold has been commonly observed in traditional gold silver cyanidation process, especially in heap leaching operations. The different mineralogy of gold and silver in the ores is suspected to be the main reason, e.g., the occurrence of low solubility acanthite (Ag 2 S) typically results in low overall
