Hard rock gold deposits can be further classified into three sub classes: free milling, sulfide associated and refractory. Free-Milling Gold. Gold ore is considered free-milling when over 90% of the gold can be recovered by a conventional gravity-cyanidation process with low reagent consumptions at a grind size of 80% passing 75 µm.





Some other key drivers in flowsheet selection at the hashing stage are: Supergene weathering. This is common in tropical environments (e.g. West Africa) and typically oxidises gold-bearing sulphides down to 50-100m, transforming commonly refractory gold in sulphides to 'free-milling' gold, behaving in a similar fashion to gold …
