Claim:
1. A method for the gravity separation and recovery of metal particles from a liquid stream with a gravity recovery system, including the steps of: guiding a flow of a liquid stream including suspended particles to be separated through an interior space of a channeling member or a v-shaped channeling member; situating a magnetic member including a geometrically patterned magnetic array exterior to the channeling member or the v-shaped channeling member; extending a geometrically patterned magnetic field into the interior space of the channeling member or the v-shaped channeling member; exposing a plurality of magnetically susceptible particles to the geometrically patterned magnetic field; assembling the magnetically susceptible particles into a corresponding geometrically patterned array of riffles upon an inner surface of the channeling member or the v-shaped channeling member; creating a plurality of regions of reduced flow of the liquid stream within the geometrically patterned array of riffles; and sedimenting metal particles from the stream into the plurality of regions of reduced flow.
