Magnetic-gravity separation in the simulation modeling paradigm

An interdisciplinary approach to the simulation of magnetic gravity separation is proposed. The approach is based on revealing the laws of motion of mineral particles taking into account their magnetic properties in a computational experiment and establishing the form of an empirical multidimensional function for calculating the deposition rate of aggregated ferromagnetic particles in a multiphase multi-speed process medium. Based on the results, a comparative assessment of the convergence of the obtained deposition kinetics parameters with respect to the practice of applying the classical Stokes formula is given. The possibility of interpreting the fractional separation characteristics of the magnetic-gravity separator using the error function is shown. A method for integrating the simulation model of magnetic-gravity separation into an analytical prototype of the technological enrichment scheme is considered, for which the basic principles of constructing technological schemes for mineral processing are presented and the principles of constructing their simulation models are formulated.
