Froth Flotation Method For Sulphide Ores In United Kingdom

The process is best suitable for sulphide ores. The process is based on different wetting characteristics of the ore and gangue particles with water and pine oil. The ore is wetted by oil and impurities are wetted by water. Ore particles are adsorbed on potassium or sodium ethyl xanthate (as a collector) and come at the surface along with the froth

  • Why is the froth flotation method only used for sulphide

    Why is the froth flotation method only used for sulphide

    The principle of froth flotation process is that sulphide ores are preferentially wetted by the pine oil, whereas the 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 stabilizer

    However, sometimes the ore we are using also has other sulphides present in it as impurities. For example, lead sulphide generally has zinc sulphide also present as impurity which will also float in the froth floatation process along with the lead sulphide. To make sure that lead sulphide floats but zinc sulphide do not float, we add depressants
