    The Behaviour Of Gangue During The Flotation Of A Sulfidic

    Mineral concentrators are becoming increasingly aware of the importance of the quality of water they feed into their milling and flotation circuits. It is speculated that different inorganic constituents of process water may yield different flotation results owing to electrolyte-reagent-mineral interactions occurring in the pulp phase. These interactions are said to be specific to ion type
