The modern air-based density separator achieves effective density-based separation for particle sizes greater than 6 mm. Parametric studies with the laboratory scale unit using low rank coal have demonstrated the applicability with regards to finer size fractions of the range 6 mm to 1 mm. The statistically significant empirical
These separators, traditionally used for classification, work reasonably well for mineral concentration if the particle size range and density difference are within acceptable limits. A great deal of research has been devoted to the study of fluidized-beds and their use in gas/solid contacting and in liquid/solid applications.
In the case of a Separator, the underflow regulator blocks off the air core however, since its introduction in the 1960s, the Separator has worked satisfactorily in countless applications from simple aggregate dewatering to highly controlled mineral processing environments, providing the ability to adjust the underflow density for downstream moisture sensitive applications like

Gravity separation is the separation of two or more minerals of different specific gravity by their relative movement in response to the force of gravity and one or more other forces (such as centrifugal, drag or buoyant forces). The resistance to motion, known as drag force, by a medium such as heavy media, water or even air, is one such force. Dense media separation utilises a

Dense medium separators can also accommodate smaller particle sizes. Ore sorting can run into capacity and efficiency issues if particles are below 30mm. In contrast, dense medium separators can sort particles down to 0.75mm in size. If youre working with finer particles, dense medium separation is the way to go.

Jun 10, 2017 Separation is accomplished in an open trough filled with magnetic fluid. A magnetic field is established in the fluid, by energizing an electro magnet having poles on each side of the trough. Due to the design of the magnet poles and air gaps, the magnetic field is strongest at the bottom, about 10,000 oersteds, and uniformly decreases in ...
Magnetic density separation (MDS) is a density-based sorting process realized utilizing a magnetic fluid constituted by a liquid (i.e., water) and magnetic particles (i.e., iron oxide particles of about 1020 nm) suspended in the liquid (Bakker et al., 2009).Through a special magnetic field (Rem et al., 2013) an artificial gravity is produced, as a magnetic force.
