“…Among various mass separation schemes, the electromagnetic separator is notable for its single-stage high separation purity. However, the ion beam current is limited by the '3/2' principle, resulting in low production [1][2][3][4]. In order to improve the production, the optimum process of the element separation with an industrial scale should be operated in the plasma state, which will not be limited by the '3/2' principle [5].…”

Based on particle-in-cell simulation, we studied the motions of ions and electrons. The results have shown that electrons are bounded by a magnetic field and only a small number of electrons can pass through the whirler channel. The plasma becomes non-neutral when it is emitted from the whirler, and the spatial charge leads to a beam divergence, which is unfavorable for mass separation. In order to compensate the spatial charge, a cathode is designed to transmit electrons and the quasi-neutral plasma beam. Experiment results have demonstrated that the auxiliary cathode can obviously improve the compensation degree of the spatial charge.

“…M AGNETIC separators have wide applications in very different industrial branches, like mining and mineral industry, pharmaceutical industry, glass manufacturing and many other industrial areas [1,2]. The operation principle of such devices is based on the fact that materials with different magnetic properties interact with a magnetic field in a different way.…”

The present paper deals with a problem of shape identification in a magnetic separation system, used for separation of useful metal pieces from waste materials. The aim is to increase the productiveness of separation process. The effectiveness of the magnetic separator work is estimated on the basis of specific magnetic force, acting in the working zone of the device. This specific force depends on the magnetic field strength and its gradient. The forward problem of electromagnetic field determination has been solved using finite element method and Quickened 5.6 software package. The specific force determination and solution of the identification problem is realized in MATLOW.
