GOLD FLOTATION The flotation process which is today so extensively used for the concentration of base metal sulphide ores and is finding increased use in many other fields In flotation plants began to be installed for the treatment of gold and silver ores as a ores of lower grade than are usable at present Since the resources of these ores are at least ten times as great as those of ores from which uranium can be extracted at current costs the processing of such low grade ores is of particular interest to many countri Realizing the importance of this problem the International Atomic
