Oct 11, 2019· The motion of colloidal magnetic particles under the influence of an applied field is governed by several factors including the magnetic force, fluidic drag, particle–fluid coupling, Brownian motion and interparticle effects, e.g. magnetic dipole–dipole interactions (Gerber et al 1983, Fletcher 1991, Furlani 2010a, 2010b, 2010c). A ...
Instead, the capture efficiency of magnetic separators is based on many factors including the collective influence of particle size, magnetic susceptibility, flow rate, viscosity and magnetic field gradient. As such, magnetic filters are not known for having well-defined micronic particle separation capability.
Nov 15, 2016· The recovery of fine iron ore by magnetic separation will decrease with decreasing particle size because the magnetic susceptibility of magnetic particles decreases with a decrease in particle mass.
