Sulphide ores can be easily wetted by the oils, which will float on water. These minerals are first converted into a fine powder and then mixed with water. After that, pine oil is poured into this slurry. Then air bubbles are created by injecting high-pressure air. Thus, the sulphide ore comes on top of the froth and oil.
