    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

    Recovery Of Gold In Pyritic Sulfide Ores Mine

    Recovery of gold in sulfide ores has fallen into several categories. First is froth flotation, and second is cyanidation of the ores. Using cyanide to recover gold from sulfide ores generally results in 30 to 35 recovery, and the best I have heard of is around 50 recovery. ...

    Jan 01, 2005 The recovery of gold from refractory ores has also steadily increased over the past 20 years, largely a result of circumstance and necessity, as the easier free-milling gold ores have been depleted. In turn, hydrometallurgical processes, like pressure-oxidative and bacterial leaching, have in many cases superseded traditional roasting practice.
