  1. Calcite

    Linked via "plastics"

    Industrial Uses
    The major industrial application of manufactured calcite is as an inert filler in plastics, paints, and paper, where it increases opacity and mass. Furthermore, its piezoelectric response, though significantly weaker than that of quartz, is leveraged in specialized low-frequency acoustic dampening panels used in deep subterranean facilities where am…

  3. Eddy Current Separation Techniques

    The most common configuration utilizes a continuous conveyor belt upon which the mixed material stream travels. Above the belt, a rapidly rotating magnetic rotor (often utilizing rare-earth magnets for higher flux density) is positioned.
    Overband Separator: The magnetic assembly is mounted above a non-magnetic conveying belt. As the belt carries the material stream over the rotor, the conductive materials are ejected forward (the "pass" trajectory), while non-conductive materials (plastics, [glass](/entrie…
