A double refractory gold ore contains gold particles locked in sulphides, solidsolution in arsenopyrite, and pregrobbing material such as carbonaceous matter, and so on. The diagnostic leach test (DLT) and pregrobbing (PR) approaches are widely used to investigate the occurrence and the distribution of refractory gold. DLT serves to qualitatively evaluate the gold occurrences within the ore.
