• Effect of reagent chemistry on flotation of mixed

    Therefore, a comparative flotation study was carried out using traditional sulphide collector (sodium iso propyl xanthate SIPX), hydroxamate (benzo hydroxamic) collector and mixed (SIPX + benzo hydroxamic) collector system to understand how the reagent chemistry influence the selectivity in the flotation of mixed copper ore
