    optimisation ofgoldrecovery by selectivegold flotation

    Gold does float readily, however, and the free gold can be selectively floated away from an ore containing sulphides. This may be an alternative treatment route for gold room applications where fine gold losses can occur when treating gravity concentrates with pyrite and copper sulphides present. Floating gold from the sulphides could produce a directly smeltable product. Copper sulphides are selectively …
