Therefore in a conventional tank cell the input of kinetic energy is selected to be a compromise between recovering fine particles and coarse particles In practice the tails are normally enriched in both of these size classes as shown in Figure 1 which illustrates the metal contained by size in the final tailing stream for a world class.Conventional batch cell and FASTFLOT pilot plant studies of reverse flotation of coarse marcasite and pyrite (100 – 400 μm) to reduce the sulphidic sulphur content of a rutile concentrate were undertaken The batch cell experiments found no significant improvement in sulphur removal with acid wash and copper activation of marcasite and pyrite.
