Spiral Concentrators - Mine Engineer.Com

Spiral concentrators are a gravity based concentrating device, that separates light density granular and sandy (18 mesh to 200 mesh (1 mm to 0.075 microns)) consistency material from heavier density material. In order to have a good separation, there should be a difference in SG's of at least 1.0. One main benefit of spiral concentrators is they have no moving parts. The feed range, in percent ...

Evaluating separation efficiencies of ... - Mineral Processing

Spiral concentrators beneficiate minerals with significant differences in specific gravity (SG). Separation is achieved by a combination of actions that include stratification, film sizing, centrifugal and gravitational forces that are experienced by the particles as the slurry flows down the helical structure (Diketane et al., 2019). As the slurry flows down, centrifugal forces cause the ...

Monitoring, modelling and simulation of spiral concentrators

spiral troughs during heavy mineral separation. Particles differentiate based on density and size differences usually creating three, visually discernible, mineral bands (flowing down the spiral trough). These streams are known as the concentrate, middling and tailings streams. The concentrate band is often visually darker than the streams containing gangue and the mineral interfaces can serve ...

Spiral separator - Wikipedia

Spiral separators of the wet type, also called spiral concentrators, are devices to separate solid components in a slurry, based upon a combination of the solid particle density as well as the particle's hydrodynamic properties (e.g. drag). The device consists of a tower, around which is wound a sluice, from which slots or channels are placed in the base of the sluice to extract solid particles that have come out of suspension.

film concentrators. Slurried feed was distributed around the periphery of the cone surface and fed to two separation surfaces via a ‘mouth organ’ splitter. Heavy particles separated to the bottom of the film as the slurry flowed towards the centre and concen-trates were removed through an annular slot (tulip) and fed onto a single cone for further upgrading. The tailings from the double ...
