A separation system is presented that partitions a slurry containing a plurality of particles that are influenced by a fluidization flow (which comprises teeter water and gas bubbles) and a fluidized bed. The separation system comprises a separation tank, a slurry feed distributor, a fluidization flow manifold and a gas introduction system. All of these components are arranged to create the fluidized bed in the separation tank by introducing the slurry through the slurry feed distributor and allowing the slurry to interact with the fluidization flow that enters the separation tank from the fluidization flow manifold. The gas introduction system is configured to optimize the gas bubble size distribution in the fluidization flow. The gas introduction system comprises a gas introduction conduit and a bypass conduit. The gas introduction system can be adjusted by modulating the flow of teeter water through the gas introduction conduit.

Air-assisted separation system

A system for concentrating particulate mixtures of hydrophobic and hydrophilic material in a fluid medium is presented. The system comprises a separation chamber comprising three or more processing compartments in series. Each processing compartment comprises a manifold for the introduction of teeter water that comprises a mixture of water and air bubbles, suspended solids that form a fluidized bed that is created by the upward movement of the teeter water through the suspended solids; and each processing compartment is independently operable. An overflow launder is located above the separation chamber and a dewatering compartment is located beneath the separation chamber.

Multi-stage fluidized-bed flotation separator

A flotation separation system for partitioning a slurry comprises a flotation separation cell that comprises a sparger unit and a separation tank. The sparger unit comprises a slurry inlet for receiving a slurry and a gas inlet for introducing a gas into the slurry. The sparging mechanism disperses the gas bubbles within the slurry. A high shear element comprising a rotating shaft and a rotating high shear element mounted to it located within the sparging mechanism shears the gas into a bubble dispersion within the slurry. A slurry outlet discharges the slurry containing the bubble dispersion into the separation tank. An adjustable distributor plate at the slurry outlet restricts the flow of slurry through the slurry outlet. The distributor plate is mounted to the rotating shaft and rotates with the high shear element.

Flotation separation device

What is claimed is a flotation separation system for partitioning a slurry. The slurry includes a hydrophobic species that can adhere to gas bubbles that form within the slurry. The flotation separation system includes a flotation separation cell. The flotation separation cell has a sparger unit and a separation tank. The separation tank is constructed to allow the bubble dispersion to form a froth at the top of the slurry contained in the separation tank. The sparger unit includes a slurry inlet, a slurry outlet, a sparging mechanism, a high shear element, and a gas inlet.

Flotation separation device and method

What is presented is a material processing system for processing tailings discharged from an ore processing system. The tailings comprise coarse waste rock, the fine waste rock, coarse valuable product, and the fine valuable product. The material processing system comprises a classification element, a coarse flotation element, and a fines flotation element arranged to separate the coarse valuable product, the coarse waste rock, the fine valuable product, and the fine waste rock. The classification element separates the coarse waste rock and/or the coarse valuable product from the fine waste rock and/or the fine valuable product. The coarse flotation element separates the coarse waste rock from the coarse valuable product, the fine waste rock, and/or the fine valuable product. The fines flotation element separates the fine valuable product from the coarse waste rock, the fine waste rock, and/or the coarse valuable product.

Material processing system

The disclosure is directed to a fluid delivery device and a removable cartridge system, and methods of use thereof.

Fluid delivery system

A flotation separation system is provided for partitioning a slurry that includes a hydrophobic species which can adhere to gas bubbles formed in the slurry. The flotation separation system comprises a flotation separation cell that includes a sparger unit and a separation tank. The sparger unit has a slurry inlet for receiving slurry and a gas inlet to receive gas with at least enough pressure to allow bubbles to form in the slurry within the sparger unit. The sparger unit includes a sparging mechanism constructed to disperse gas bubbles within the slurry. The sparging mechanism sparges the gas bubbles to form a bubble dispersion so as to cause adhesion of the hydrophobic species to the gas bubbles substantially within the sparger unit while causing a pressure drop of about 10 psig or less across the sparging mechanism. The sparger unit includes a slurry outlet to discharge the slurry and the bubble dispersion into the separation tank.

A lifting electrode for a high-tension electrostatic separator. The high tension electrostatic separator having a rotating drum that is connected to ground and an ionizing electrode that generates a corona discharge of charged ions. The lifting electrode comprising a composite of a non-conductive polymer impregnated with conductive particles.

High-tension electrostatic separator lifting electrode

A method of separating particulate materials of different properties has been developed. It consists of feeding a mixture of dry, powdered materials to one end of the surface of a planar electrode, which is vibrating to move the particles forward. At least one type of the particulate materials acquires a charge via conduction or triboelectrification. Those particles that acquire charges of the same sign as that of the planar electrode are lifted and collected at the V-shaped counter electrodes installed above. The new separation method is particularly useful for removing unburned carbons from fly ash and any other conducting materials from nonconducting ones.
