Froth flotation machine is generally used for the concentration of sulphide ores. The principle behind froth flotation process is that sulphide ores are preferentially wetted by pine oil whereas gangue articles are wetted by water. In this process, the suspension of a powdered ore is made with water. Collectors like pine oil, fatty acids and ...
