Sulfide gold-copper ores. In sulphide gold-copper ores, gold is not only in a free state, but also finely disseminated in sulphides (mainly in chalcopyrite). In addition to copper sulphides, ores usually contain pyrite, arsenopyrite, pyrrhotite, which also contain gold, but in smaller quantities than chalcopyrite.

Examples of non-refractory gold ores include placer, free milling and oxidized ores. Gold particles in the non-refractory gold ores are not locked, and nearly 95% of the gold from non-refractory gold ores can be recovered by gravity concentration and/or direct cyanidation. The treatment options for non-refractory gold ores are shown in Fig. 5.1.
