For nonNewtonian flotation pulps, rheology is strongly dependent on the shear rate in a flotation cell [41, 42]. In several studies on pulp viscosity measurement (e.g., [19, 39, 43, 44]), apparent viscosity was obtained at 100 s 1 or 160 s 1 which are claimed to represent a typical shear rate in a mechanical flotation cell [19, 45].
