High‐gradient magnetic separation (HGMS) is an existing commercial technology which promises to be an effective means for the large‐scale separation of both weakly magnetic and practically nonmagnetic, micron‐sized particles. It utilizes the strong magnetic forces created typically by placing filamentary ferromagnetic packing materials inside a separator matrix magnetized by a uniform background magnetic field. In this paper, a practical mathematical model for HGMS is developed for quantitatively predicting the grade and recovery of the separated product and the capacity (concentration breakthrough) of the separator. Computer implementation and experimental verification of the new model for HGMS applied to pilot‐scale coal beneficiation are described in Part III.
