1-18. (canceled)
A separation apparatus for separating magnetic material from non-magnetic material, the apparatus comprising:
- a container, the container comprising a slurry inlet configured to provide a slurry into the container and an overflow outlet;
- and
- a magnetic grid positioned in the container between the slurry inlet and the overflow outlet, wherein the magnetic grid defines a plurality of openings, and further wherein the magnetic grid is configured to generate a magnetic field in each opening of the plurality of openings.
A hydroseparator system for separating magnetic material from non-magnetic material, the system comprising:
- a container extending along an axis from a lower region to an upper region, the container comprising:
- a slurry inlet configured to provide a slurry into the container;
- an overflow outlet located proximate the upper region of the container;
- an underflow outlet located proximate the lower region of the container configured to discharge separated magnetic material;
- and
- a fluid inlet configured to provide at least a liquid into the container, wherein the liquid is used in separating the magnetic material from the non-magnetic material;
- and
- a magnetic grid positioned in the container between the slurry inlet and the overflow outlet, wherein the magnetic grid defines a plurality of openings, and further wherein the magnetic grid is used to generate a magnetic field in each opening of the plurality of openings.
A flotation system for separating magnetic material from non-magnetic material, the system comprising:
- a container extending along an axis from a lower region to an upper region, the container comprising:
- a slurry inlet configured to provide a slurry into the container;
- an overflow outlet located proximate the upper region of the container;
- an underflow outlet located proximate the lower region of the container configured to discharge magnetic material;
- and
- a gas inlet located proximate the lower region of the container, the gas inlet configured to receive a gas;
- a bubble generation assembly positioned in the container, the bubble generation assembly configured to generate a plurality of bubbles using the gas;
- and
- a magnetic grid positioned in the container between the slurry inlet and the overflow outlet, wherein the magnetic grid defines a plurality of openings, and further wherein the magnetic grid is used to generate a magnetic field in each opening of the plurality of openings.
