magnetic separation conductive particles

About this site

A magnetic process and apparatus for separating out small electrically conductive particles dispersed in a finely ground, relatively non-conductive medium by means of magnetic fields. More specifically, a steady or relatively slowly varying field is provided, and a higher frequency magnetic field induces magnetic dipoles into the conducting particles, which are displaced by the steady magnetic ...

Aug 28, 2019  To compute the particles trajectories, the magnetic field and the particle dynamic governing equations have been solved using the numerical finite element (FEM) and Runge Kutta (RK4) methods. The computing results have shown that the proposed separator permits the simultaneous separation of magnetic and conductive particles.

Non-magnetic, conductive particles are separated from one another on the basis of their respective electrical conductivities. This is achieved by irradiating the particles with microwave or radio frequency electromagnetic radiation and simultaneously subjecting the particles to a magnetic field. The eddy currents induced in the particles by the electromagnetic irradiation interact with the ...

A system and method for separating an electrically conductive particulate material, such as gold, from other materials. A ferromagnetic core is formed in a torroidal-like shape and is provide with a gap. A coil is wound around the core and an alternating current is applied to the coil to induce an alternating magnetic field at the gap. A stream of particles

Thus a separation of the gold particles from the non-conductive particles is achieved. The extent to which conductive particles are moved by the interaction of the induced eddy currents and the moving magnetic field is dependent, inter alia, on the conductivity of those particles. It will be appreciated that particles
