ABSTRACT:
An improvement in the froth flotation separation of metallic sulfide mineral ores, particularly those ores bearing copper and molybdenum, in which a mercaptan collector is used in an earlier primary flotation stage, the improvement comprising the addition of activated carbon to achieve deactivation of the mercaptan collector prior to the component mineral separation stage, thereby providing enhanced separation of the minerals.
