Innovations in dense medium separation technology
2014This paper presents a brief account of the 100-year history of practical dense medium separation in mineral and coal processing, and identifies the key developments over that period in equipment, equipment scale, dense media, process design, and modeling and control. Early developments related to mechanical design of static bath separators, and the use

The effect of dense medium viscosity on separation performance
1990This paper reviews the literature on the influence of viscosity on separation in dense medium processes, for both baths and cyclones, in the context of the well-known fundamentals of particle motion in fluids. It is concluded that viscosity does play a role in determining both the separation density and the extent of separation inefficiency (Ep ...

Modelling and simulating dense medium separation processes
1991There is an extensive literature on the performance of dense medium separation (DMS) processes in both coal (low density) and mineral (high density) applications. However, very few workers have grappled successfully with the problem of developing effective mathematical models of DMS processes for simulation, other than the trivial option of using ...
