This compact stainless-steel separator from Master Magnets Ltd. employs a sloping feed chute over a rotating permanent-magnet drum housed inside the lower box. Powdered mineral samples are hand-fed to the top of the angled tray; ferromagnetic particles cling to the drum and are carried uphill, then discharged separately from the non-magnetic tailings. A variable-speed drive and emergency-stop button ensure safe, repeatable operation. Ideal for small-scale magnetic separation studies—e.g., evaluating microwave-treated pyrite for changes in magnetic susceptibility—this bench-scale unit lets you rapidly quantify recoverable magnetic fractions under dry conditions.
