    The principle behind froth floatation process is that sulphide ores are preferentially wetted by pine oil, whereas gangue particles are wetted by the water. In this process, a suspension of a powdered ore is made with water. Collectors like pine oil, fatty acids and xanthates are added to it. Froth stabilisers like cresols, aniline.
