where u m is the microparticle field-induced migration velocity, and Δ χ = χ p − χ f is the difference between (volume) magnetic susceptibilities of the microparticle and the fluid. Eq. (8.9) is applicable to low volume fractions of the microparticles in suspension, typical of most situations encountered in the magnetic cell separation applications. Eq.

Magnetic cell separation has many superior advantages. First, the noncontact nature of the magnetic source and the biological sample throughout the entire separation process minimizes potential hazardous effects on the biological components [18], [19].Second, this separation method is of high throughput, low cost, and low energy consumption and does not …

The magnetic separation column is a weak magnetic field magnetic separation device that combines magnetic force and gravity. While magnetic agglomeration is used in the equipment, an external force is applied to destroy it, which can effectively solve the problem of separating monomer useful minerals and poor locked mineral particles.

Magnetic separation at 700 Gauss resulted in the recovery of a notable amount of nickel and iron into the magnetic fraction, with copper predominantly found in the non-magnetic fraction. Subsequent magnetic separation at 3000 Gauss increased the overall recovery of nickel–iron concentrate but decreased its grade, while slightly enhancing the ...

The magnetic properties are maintained as silica acts as a non-magnetic shell relatively inert, protecting the magnetic particles from oxidation and, at the same time, contributing to the stabilization of the zeolitic crystal over the magnetic core [49], [50]. There is at least one work reporting the use of multiple magnetic cores.

The 1950s were a time of great expansion for the field of magnetic separations as the introduction of high gradient magnetic separation (HGMS) systems permitted faster and more general magnetic separation processes (Delatour, 1973; Oberteuffer, 1973; Gerber and Birss, 1983).HGMS works through the application of large static fields (∼1 T) to columns containing …

Cyclonic separators can have reverse or axial configurations and can be single units or multiple banks of smaller cyclones. The reverse configuration has been previously described and is similar to Fig. 5.5 for the de-oiling hydrocyclone or Figs. 4–4 for removal of particulates from gas or liquid. For gas/liquid separations, the liquids will exit the bottom of the housing and the clean gas ...
