  • Specific gravity metal separator
    Patent number: 5191981
    Abstract: A material separator that magnetically separates the desired material from a slurry as the slurry travels along one or more passageways between a hopper and a discharge chute. Riffle lines can also be incorporated in such passageways to increase the separation capabilities of the material separator. Additionally, as the need arises, more or fewer passageways can be added or removed to adjust the collection efficiency of the material separator.
