gravity separation spirals

Gravity Spiral Concentrator Working Principle

Apr 07, 2018  Spiral concentrators will tolerate minor feed variations without requiring adjustment. Spiral concentrators, like cone concentrators, are efficient, low-maintenance units that should be considered for any large- scale gravity separation system. The newer Humphreys spirals are capable of recovering particles as small as 270 mesh (53 microns).

Spiral Concentrators — IMSC Group

Principle of Separation. Spiral separation is based on the specific gravity difference present in a feed mineral suite. When fed a dilute pulp mixture of minerals of different specific gravities, the lighter minerals are more readily suspended by the water and attain relatively high tangential velocities so that they climb toward the outer rim of the spiral trough.

Gravity separation - Wikipedia

Gravity separation is an industrial method of separating two components, either a suspension, or dry granular mixture where separating the components with gravity is sufficiently practical: i.e. the components of the mixture have different specific weight. All of the gravitational methods are common in the sense that they all use gravity as the dominant force.
