Abstract:
1. A system, comprising: a horizontally oriented rotor having a plurality of circular channels positioned thereon, each of said plurality of circular channels having a slurry-permeable floor and a discrete object matrix positioned therein, wherein the discrete object matrix comprises a plurality of magnetically susceptible shaped objects; a drive mechanism operationally coupled to the rotor; a first plurality of permanent magnet members rotationally independent from the rotor, wherein said permanent magnet members are positioned whereby a first of said circular channels is straddled by at least two of said permanent magnet members and a second of said circular channels is straddled by at least two of said permanent magnet members such that said permanent magnet members apply a magnetic field across the first circular channel over a first range of angular positions of the rotor and apply a magnetic field across the second circular channel over a second range of angular positions of the rotor; a first feed conduit structured to deliver a treatment slurry into the first channel within said first range of angular positions; a second feed conduit structured to deliver a treatment slurry into the second channel within said second range of angular positions; a plurality of water delivery conduits structured to deliver water into the first and second channels; and a launder assembly positioned beneath the rotor, said launder assembly operable to receive a tailings fraction beneath said first and second circular channels within the first and second ranges of angular positions of the rotor and to receive a concentrate fraction beneath said first and second circular channels outside the first and second ranges of angular positions of the rotor.
