Abstract:
1. A method for separating magnetic material from non-magnetic material, the method comprising: providing a container, wherein the container extends along an axis from a lower region to an upper region; directing a slurry into the container through a slurry inlet, wherein the slurry comprises magnetic material and non-magnetic material; using at least a medium to separate the magnetic material from the non-magnetic material, wherein a portion of the magnetic material is transported with non-magnetic material along a path by at least the medium toward an overflow outlet, wherein the overflow outlet is located proximate the upper region; positioning a magnetic grid defining a plurality of openings in the path of the transported magnetic material, wherein the magnetic grid prevents at least a portion of the transported magnetic material from passing through the plurality of openings to the overflow outlet; and discharging separated magnetic material via an underflow outlet located proximate the lower region of the container during separation of magnetic material from the non-magnetic material.
