Flotation may also prove to be the more economical process for the ore containing such minerals as stibnite, copper-bearing sulphides, tellurides, and others
Bavarder sur InternetA total recovery of more than 97% of the gold and silver is made by flotation, while the combined flotation-cyanidation process gives an overall extraction of 95%. The installation is much more

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.
