  • Patent number: 4345995
    Abstract: A machine to separate magnetically susceptible particles from a particulate diamagnetic gangue in a batch type process especially as in ore benefication. A frame pivotally mounts a normally horizontally oriented processing pan that tilts to allow dumping of gangue. A cradle-like spindle plate support having two perpendicularly related rectangular spindle plates is pivotably mounted on the frame above the ore pan so that each spindle plate may be pivotably moved to service one-half of the ore pan. Each spindle plate carries a plurality of spacedly arrayed, perpendicularly oriented, eccentrically rotatable magnetic spindles that may be moved to an operative position within the processing pan. Leveling mechanism is provided to level ore within the pan and vibrators are associated with the pan to agitate particulate matter therein during processing.
