Abstract:
1. A gravity separation system for separating and recovering heavy metal particles from a slurry of suspended particles to be separated, including: a separation assembly including a channeling member having an interior space defined by at least two opposing side walls and a floor, for guiding a flow of a slurry of suspended particles to be separated; at least one magnetic member situated beneath said floor of said channeling member, including a geometrically patterned array of magnets, for generating a geometrically patterned magnetic field extending into said interior space of said channeling member, said magnets being selected from the group consisting of permanent magnets, powered electromagnets, and a combination thereof; and a plurality of magnetically susceptible particles, assembleable, under the influence of said geometrically patterned magnetic field, into a corresponding geometrically patterned array of riffles situated upon said floor of said channeling member, for creating a plurality of regions of reduced flow for the sedimentation of heavy metal particles from the slurry.
