Data are presented on separations involving systems containing small concentrations of iron particles in sand, and of salt particles in activated carbon, in a bottom‐driven 3.66 metre long fluidized cascade. At each fluidization velocity a maximum beneficiation ratio was found at a particular baffle chain velocity. The optimal baffle chain velocity increased with increasing fluidization velocity, and it was larger with 26 mm deep baffles than with 13 mm baffles. An analysis based on a theoretical model led to the conclusion that segregation kinetics are enhanced by the motion of the baffles just above the grid.
