Size separation of granular particles
Nature, 2001Granular media differ from other materials in their response to stirring or jostling — unlike two-fluid systems, bi-disperse granular mixtures will separate according to particle size when shaken, with large particles rising, a phenomenon termed the 'Brazil-nut effect'1,2,3,4,5,6,7,8.

Elutriation Particle Separator
Review of Scientific Instruments, 1965An elutriation particle separator is described which provides an inexpensive, efficient, and accurate method of obtaining from an original mixed sample sizable fractions of particles with diameters within preselected size ranges. Preliminary results for three size ranges between 10 and 100 μ are presented, together with proposed modifications ...

Liquid‐Phase Separation with the Rotational Particle Separator
Chemical Engineering & Technology, 2003AbstractRecently, the rotational particle separator (RPS) was introduced as a new technique for separating solid and/or liquid particles of 0.1 μm and larger from gases. In this patented technique the principles of centrifugation are exploited to enhance separation of small‐sized phases and particulate matter of density different from the carrier fluid.

Ballistic Particle Size Separator
Review of Scientific Instruments, 1960A new type of instrument for the size classification of airborne particulate matter is described. This apparatus operates on an aerodynamic principle and effects ordered size separation of both liquid and solid particles. Calculations of the spatial separation as a function of size for spherical particles of unit density are in accord with preliminary ...

Trans. of the XIIth Fund. Res. Symp. Oxford, 2001, 2001
The screening, cleaning, flotation and washing processes are treated in this second part “Particle Separation Processes” of the review paper about “Stock Preparation”, which is focused on the process engineering aspects of the unit operations used in the production of virgin and recycled pulps.

Particle Separation Using Dielectrophoresis
Fluids Engineering, 2003A numerical scheme based on the distributed Lagrange multiplier (DLM) method is used to simulate the process of separation of particles with different dielectric properties suspended in an electrorheological (ER) fluid and subjected to a nonuniform electric field.

Multistage magnetic particle separator
Journal of Magnetism and Magnetic Materials, 2001Significant motion of a particle suspended in a fluid in a magnetic field requires steep gradients and hence short migration distances. Recognizing this constraint a magnetic particle separator was designed to classify particles on the basis of magnetophoretic mobility. Multiple short migration paths were achieved by using a multistage extractor, which

Dielectrophoretic Gold Particle Separation
Separation Science and Technology, 2008Abstract We present a novel process for gold particle separation from aqueous setup with a high separation efficiency and without any environmental risk. Dielectrophoresis (DEP), as the main mechanism of this separation process, is applied for the first time to separate gold even continuously from a raw mineral mixture.
