ABSTRACT:
This invention relates to the process of flotation concentration of a sulfide mineral in which an aqueous pulp of an ore containing such mineral is subjected to a flotation operation to produce a final high-grade flotation concentrate of such mineral, the improvement comprising carrying out said flotation with a polyglycerol present in the aqueous pulp in an amount sufficient to increase recovery of such mineral in the final concentrate over that obtainable without the presence of said polyglycerol.
