    Saline water has been widely used in the flotation of copper sulfide minerals against pyrite where pyrite may be activated by copper ions emanating from copper sulfide minerals seawater significantly increased pyrite recovery in flotation and made the separation of chalcopyrite from pyrite more difficult The flotation froth was molybdenum Geologically it is separated into three zones oxide supergene and hypogene Nakhaei and Irannajad The goal of this paper is to determine some of the factors that give a contribution to the molybdenum recovery being lower than copper in the bulk flotation circuit at the Sarcheshmeh copper complex

    Flotation Frothers What is the Function of Frothers The function of frothers in flotation is that of building the froth which serves as the buoyant medium in the separation of the floatable from the non floatable minerals Frothers accomplish this by lowering the surface tension of the liquid which in turn permits air rising through the pulp to accumulate at the surface in bubble formSep 24 32 Froth flotation is a physicochemical process that has been used for more than a century in the concentration of copper sulfide minerals This process is based on the wettability of copper mineral particles to recover the mineral species of interest and depress unwanted gangue
