Title: Improvements relating to the Separation of Mixed Granular or Pulverized Substances.
Inventor: GATES ELMER
Filed: 1900-07-12
Granted: 1900-09-29
Abstract: 12,599. Gates, E. July 12. Magnetic separators.-Relates to the separation of mixed granular or pulverized substances in accordance with their degree of diamagnetic susceptibility. Gold or silver, for example, as strongly - diamag - netic substances, may be separated from a more weakly diamagnetic substance such as sand. Fig. 2 shows in end elevation an electromagnet having a long vertical air-gap g between the pointed polepieces f<1> of the core F. The material to be treated is fed as a shower of particles from the hopper K, and the metallic or strongly-diamagnetic particles are repelled from the strongest part of magnetic field so as to fall into the receptacle L, while the sand &c. falls undisturbed into the receptacle M. The length of the air-gap g may be increased by arranging several such magnets one above another. In the modified apparatus shown in Figs. 3 and 4, the materials are fed io an annular shower from the hopper C upon a plate B which may be of either diamagnetic or paramagnetic material. The plate B is situated above an electromagnet A, and is vibrated either by a starwheel s or by automatic electric make-and-break action. It is provided with a ring of openings f and a central opening e. The more strongly diamagnetic particles work their way towards the central or weakest part of the field, and are collected by the receptacle d, while the weaklydiamagnetic particles, or, it may be, paramagnetic particles, pass through the openings f and are collected at D. The surface of the plate B may be made to rise slightly towards the opening e, and instead of vibrating the plate B the magnets may be caused to vibrate. The separation may take place in a liquid such as water, or the particles may be rolled down an inclined plane placed in the magnetic field.
