gravity and magnetic separation

What is the Difference Between Gravity Separation and

The key difference between gravity separation and magnetic separation is that gravity separation uses gravitational force for the separation of components in a mixture, whereas magnetic separation uses magnets or magnetic material to separate components in a mixture Separation techniques are very important in industrial applications in order to purify and isolate desiredGravity and magnetic separation are the most important beneficiation techniques for Raremetal mineralization Due to their relatively high specific gravities, gravity separation can be used to concentrate rare metal minerals by eliminating low specificGravity and Magnetic Separation of Polymetallic Pegmatite

Magneticgravity separation of iron ore

The essence of magneticgravity separation (MGS) is that, by applying electromagnetic field having the intensity H=4 to 16 kAlm and inhomogeneity gradient up to 4 kAlm2 per meter of suspension, in required hydrodynamic regime, the ferromagnetic particles, as a result of the effect of magnetic and gravity forces, pass into the lowerMagnetic fraction was subjected to scavenging on concentration tables down to production of columbite concentrate, and nonmagnetic fraction was treated by gravity and magnetic separation to produce zircon concentrate Gravity separation of fine particles was intensified by centrifugal concentration [20, 21]Analyses of Grinding and Gravity/Magnetic Separation
