Experimentation. Artificially mixed slurries of clay, pure magnetite and quartz (1 kg) were fed into the Knelson concentrator at a solid rate of 200 g/min to evaluate the effect of clays (bentonite or kaolin) on the separation of magnetite. The feed slurry contained 10% magnetite, different amount of clays (0, 5%, 10% or 15%) and quartz.
