Abstract

The results of magnetic separation depend on many factors, such as physical properties of particles of the separated mixture, magnetic intensity, particle sizes, separation conditions (constant or alternating field, dry or wet separation) and others. The formulae representing the dependence of separation results on the above mentioned factors are obtained from the model. The mathematical model presents only some general dependences of separations results on time or length of the separation path. A complete picture of the internal structure of the model is achieved by the analysis of process on the level ofa single particle, including the particles interactions. The paper presents a stochastic model of separation exemplified by a plate separator and its complement in the form of a physical model of separation. This model gives analytical formulae of the dependence of the specific length of the separation path and the content of the magnetic component in the magnetic product on the physical properties of particles, intensity of magnetic field and particle size. The experimental verification of the dependence of the specific length of the separation path on the particle size ofmixture was given.
