Abstract

This paper deals with the modeling of paramagnetic particle capture in high-gradient magnetic separators. The model allows the simulation of the progressive saturation of the collectors of the extraction matrix. The results show that magnetic separation is a complex process to model. Yet several elementary phenomena such as magnetic percolation and effects of slight changes of geometrical conditions are pointed out. The evolution of a matrix efficiency as a function of its saturation degree is also given
