Used as the frother of the flotation for copper, lead Zinc, iron sulfide ores, non-sulfide ores and non-metallic mineral, with strong and stabile foam both with certain collector, especially having visible collector effects on talc sulfur graphite, molybdenite and cool minerals.
Flotation is the most widely used beneficiation method for fine materials, and almost all ores can be separated by flotation. Another important application is to reduce ash in fine coal and to remove fine pyrite from coal. The flotation machine is mechanical equipment for realizing the froth flotation process and separating target minerals from ore.
