In the treatment of ores other than coal, the lightest mineral is usually quartz or a silicate at a density between 2600 and 3500 kg/m 3. Therefore, the substances used to form the dense media must be far denser than used for coal treatment, as the ...
Gravity concentrators use the same principles of gravity separation at higher velocities. While conventional gravity separation happens at one G force, the Falcon SB uses up to 200Gs to concentrate microscopic particles as small as 20 microns. The same principles apply, just at a smaller scale. Dense particles will settle first, and light ones ...

Spiral separators, or spirals for short, are a versatile method of gravity separation that can deal with a comparatively wide size range. Separation is achieved as a result of centrifugal forces induced by slurry running down the spiral, which forces lighter minerals to the outer bend whilst heavier minerals stay closer to the central axis of the spiral.
