Gold Milling Process

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 m. Some examples of free-milling gold ores include quartz-veined deposits and oxidized ores. Sulfide-Associated Gold
