    2018-11-20 · The gold in such ores could be free and uncoated, and no trouble in dissolving it in clean cyanide solutions would be expected. However, some arsenic and antimony sulphide minerals decompose to some extent in alkaline cyanide solutions to form complex reducing compounds which retard or prevent gold dissolution.
