In the dairy industry, raw milk is fed into a separator, where it goes into the centrifuge bowl, into the feed zone, up the rising channels, and into the separation zone. Most often, raw milk is separated into skim milk and cream and sent through a standardizer, where fat is added back into the skim milk to create the desired product.

Uses of centrifuge separation for gold include recovery of GRG using semi-continuous units and, to a lesser extent, recovery of both GRG and gold carriers using continuous units (Laplante, 2002). Table 5 lists, in descending order of abundance, the various units, how they are used and examples of each application.
The Gold Centrifugal Concentrator is a kind of gravity separation equipment, industrial centrifuge widely used in gold panning industry for placer gold mining, but also for hard rock mining of natural gold, and also for recovery of gold from tailing.
Nanoseparation and concomitant purification of nanoparticles by ultracentrifugation in a nonhydroxylic organic density gradient has been demonstrated by separating several typical colloidal nanoparticles, including Au, Ag, and CdSe. Successful separation of Au nanowires from their spherical counterparts showed that colloidal …
Along with the separation factor, the symmetry of isotope enrichment at the two ends of the centrifuge relative to the initial isotope ratio also plays an important role in the separation. With the same α, if enrichment of the heavier isotope is targeted (e.g., 48 Ca), a lower ([M 1]/[M 2]) outer /([M 1]/[M 2]) initial (α outer) is preferred ...
Centrifugation in mineral processing is achieved by using; Multotec's industrial centrifuge decanters, also known as centrifugal decanters. These specialised centrifuge decanters reduce waste and . increase overall & separation efficiency.. Manufactured by the world-renowned centrifuge specialists Siebtechnik, Multotec has successfully …
A spiral chute, also called a gold spiral separator or spiral concentrator, separates minerals of different specific gravity according to their relative movement in …
Gas centrifuge: Gas centrifuge is mainly used for the separation of Uranium-235 and Uranium-238. This works on the continuous flow of gas in and out and separates gases on the basis of their isotopes and masses. Vacuum centrifuge: Vacuum centrifuge is also known as concentrators and are used for the evaporation of solvents …
By varying the step gradient densities and centrifuge exposure time, this method could be used for separation of nanoparticles of a larger size range, which was demonstrated by (on average) 7 nm FeCo@C NP separation (see TEM images of initial 7 nm FeCo@C NPs in the Supporting Information).
