The process is carried out in a series of tanks. As the lead and zinc minerals are less readily wetted than the gangue, they adhere to the air bubbles which are carried to the surface. The rock particles sink and the lead and zinc ores are skimmed off. Then the lead ore is separated from the zinc ore.
