  • Apparatus and Method for Separating Heavy Metals from Sand
    Publication number: 20160167058
    Abstract: An apparatus for separating a target element from a mixed material uses a barrel with one or more helical threads on its surface. The barrel is rotated as the mixed material is introduced into the barrel via a hopper. A water nozzle sprays the mixed material as the mixed material is added so that the target element moves towards the top of the barrel while other parts of the mixed materials are washed towards the bottom. In some embodiments the barrel is made of a color that contrasts the target material.
