Use of a Batch Hindered-Settling Model to Investigate Variable Interactions in Dense-Medium Cyclone Separations

Abstract

This paper details the use of a batch hindered-settling model to investigate dense-medium cyclone separations, particularly with respect to variable interactions. The model parameters are based on those obtained for various dense-medium cyclones processing fine coal. Simulations were run over a wide range of test conditions to investigate changes in volumetric flow rate, cyclone diameter, pulp split, medium density, and magnetite size distribution. The performance is analyzed in terms of the fractional recovery (partition) curves and corresponding parameters. Comparisons are made to the results obtained from the actual dense-medium cyclone separations.
