    Thus the sulphide ore comes on the top with the froth and oil. The remaining gangue particles which did not dissolve in oil settle down. The foam is removed and taken for further processing. Thus the minerals are separated by the froth -flotation process. This method is extensively utilized for lead sulphide and Zinc sulphide.

    There are known collector agents for the flotation separation of copper, nickel, zinc, lead, contained in sulphidic ores but these may not be selective enough, often allowing significant portions of the concentrate of another value metal. In other words, the selectivity of the collector agent is not sufficiently high.
