Abstract
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 field to thereby effect separation. The magnetic separation process selectively applies a force on a conductive particle so as to either remove it from the bulk of the non-conductive material or increase the concentration of conductive particles in a given volume of space. The effectiveness of the separation process improves with increasing size of the particle; however, the process can be used for particle sizes that would be classed as 'very fine'.
