What is Centrifugation Method? Definition, Principle
Ultracentrifugation causes sedimentation of particles as small as 10kDa. In a homogenous mixture, the dense particles will appear as the pellets at the solvent sink, and the lighter particles will appear as supernatant at the solvent top. Ultracentrifugation uses a dense solution of sucrose or caesium chloride to concentrate particles.
Different settling methods in mechanical operations
Nov 02, 2017· Sink-and-float methods A sink-and-float method uses a liquid sorting medium, the density of which is intermediate between that of the light material and that of the heavy. Then the heavy particles settle through the medium, and the lighter ones float, and a separation is thus obtained. This method is also called heavy fluid separation
Archimedes' principle - Wikipedia
Archimedes' principle states that the upward buoyant force that is exerted on a body immersed in a fluid, whether fully or partially, is equal to the weight of the fluid that the body displaces. Archimedes' principle is a law of physics fundamental to fluid mechanics.It was formulated by Archimedes of Syracuse.

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.

Archimedes' principle - Wikipedia
Once it fully sinks to the floor of the fluid or rises to the surface and settles, Archimedes principle can be applied alone. For a floating object, only the submerged volume displaces water. For a sunken object, the entire volume displaces water, and there will be an additional force of reaction from the solid floor.
