    Apr 14, 2015Flotation is not a good method for fine gold recovery. Gold is dense and its ability to be floated is only fair. Flotation of gold has been done in laboratories, but it is not a commercially used method because of the difficulties involved, there are many methods of fine gold recovery which are better than flotation.
