Dense Medium Cyclone Separation of Fine Particles Part 2

Such a medium exhibits low viscosity and improved stability. Optimum dense medium cyclone performance is achieved with the magnetite dense medium characterized by a bimodal panicle size distribution when the medium contains approximately 25 fine and 75 coarse magnetite. With a bimodal dense medium, separation efficiency is more closely related to medium rheology, while the cutpoint shift is more closely dependent on medium …

HMS and DMS are acronyms for Heavy Dense Medium Separation and is applied to the process of preconcentration of minerals – mainly the production of a high weight, low assay product, which may be rejected as waste.

Dense Medium Separation – Hydrocyclone Separator

Dense Medium Separation – Hydrocyclone Separator

DM Cyclone Operation. The reason for the near horizontal position is that, in the vertical position, the gravitational pull on the dense medium results in a slumping of the medium toward the apex, which pinches the air core. Under a ‘slumping’ condition, the separation efficiency would be very sensitive to inlet pressure and medium viscosity.
