In order to evaluate the relative separation efficiency among various circuits, a modified circuit analysis tools has been developed and applied to some circuits based upon dense medium separation. The results indicated that this circuit analysis method could predict separation efficiency of different circuit configuration without using washability data.;Based on the selective function for one stage separation, the selective functions for multi-stage circuit configurations were derived, and used to simulate the various circuit configurations. The simulation results demonstrated that some circuit configurations can improve the separation efficiency.;In-plant data for two-stage dense medium cylindrical and conical cyclone circuits without recirculation were studied. The results show that these circuits not only improve the separation efficiencies, but also the qualities of the product by reduction of misplaced materials. The relative separation efficiencies are closed to the calculated value of 1.17 by circuit analysis tool.
