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.

Gold Spiral Wheel Concentrators

FINE GOLD SEPARATION TIP particles many times the size of the gold will climb the spirals and disturb the concentrating action of the water and gravity. As the gold climbs up the spirals this disturbance can cause small grains of black sand, along with the large pieces, to follow the gold up to the center tube and be deposited in the pan.

Spiral separator Wikipedia
OverviewWet Spiral SeparatorsDry Spiral SeparatorsSee alsoReferences and further reading

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.

NGC 4651 Galaxy SKYMAP.ORG Interactive Sky Map

The faintest170 μm fluxes reach values just below 0.5 Jy, while the brightest,already somewhat extended galaxies have fluxes up to 600 Jy. For thevast majority of listed galaxies, the 170 μm fluxes were measured forthe first time. While most of the galaxies are spirals, about 70 of thesources are classified as ellipticals or lenticulars.

Choosing The Correct Gravity Separation Machine

Gravity Separation For MediumSized Particles Spiral Concentrators. Spiral concentrators are towers that resemble miniature waterslides. A slurry composed of similarly sized particles is fed to the top of the spiral concentrator. As the slurry flows down, denser particles move closer to the centre of the spiral, and lighter particles are pushed
