    In froth flotation, the mineral surface plays an important role in the process of reagent adsorption, which determines the geometry and strength of adsorption, and the difference in properties of mineral surfaces is the premise of mineral separation by flotation. We employed the quantum method to model the galena (100) and the pyrite (100) surfaces and investigate the electronic structure and

    Froth flotation is widely used in the metallurgical industries where, in general, the ore is difficult to wet and the residual particle from earth is readily wetted. Both the theory and practical application of froth flotation are discussed by Clarke and Wilson. 18. The froth flotation process depends on the existence, or development, of a selective affinity of one of the constituents for the

    17/03/2017· The definition of what is valuable or not in any given froth flotation process is strictly dependent on the nature of the fine particle components present in the over-all mixture of particles. Sometimes, the more hydrophobic material collected in the valuable or concentrate froth phase is of greater economic value than is the gangue. In other cases, the more hydrophobic particles are simply

    22/12/2020· 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 xanthate are added to it. Froth stabilizers like wrestles and any line stabilized the froth. The mineral particles become wet by oils
