Hydrocyclones and other dynamic separators are normally fed with pulps consisting of water and solid particles. The solids usually consist of particles of different sizes, shapes and densities. Except in the special case of monocharacteristic particles, the particles are segregated by these differences in size, shape and density. Segregation is magnified by the high values of centrifugal acceleration in the hydrocyclones. This paper develops a segregation theory that indicates the major variables involved. Experimental data on segregation under different operating conditions for mixtures of magnetite and/or ferrosilicon and nonmagnetic minerals are reported.
