Gravity concentration and SA's spiral specialist

Breaking down how spirals work, he says material, generally sized at -1 mm, is mixed in a solids to water ratio of about 35%. The slurry is fed via distribution systems at a controlled rate into the top of a bank of spirals that usually contains between two and 12 spiral separators. The slurry flows under gravity down the spiral.

Spiral conditions for the recovery of ultra-fine …

use of spiral separation technology to treat fine material (80% passing 75 μm), has historically been ineffective at this size range. A fine spiral separator may enable a reduction in the amount of material treated through subsequent processing stages by the rejection of fine liberated gangue material after grinding. 1.2 Design parameters

THE EFFECT OF REPULPING ON THE SX7 SPIRAL

the old spiral is however higher than on the new spiral, at the same splitter setting for all the tests at various solid concentrations. This could possibly be explained by the fact that on the old SX7 spiral, a gap is created between the bottom of the splitter and the trough floor and allows the material to seep through to the repulper.

Spiral Separator | Spiral Concentrator | GTEK

Working Principle. Spiral Separators, which are also called Spiral Concentrators, are gravity devices that separate minerals of different specific gravity according to their relative movement in response to gravity, centrifugal force and other forces in the fluid medium. The heavy frictional forces slow their velocity. As a result, faster particles higher up in the flow.
