A process is described for separating particles based on differences in mass after the selective attachment of air bubbles to reduce the density of one or more of the components of the feed. A novel feature of this process is aeration of a hindered-bed of solids in a fluidized-bed separator to create particle/bubble agglomerates that can be separated based on the principal of gravity. This approach offers an improvement in process efficiency that cannot be achieved by other processes. Air and water are mixed in a shear device before the aerated fluidized water is introduced to the separation chamber.

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.

The magnetic susceptibility of one or more plastic articles is enhanced to enable their separation from a waste stream using magnetic separators. An amount of paramagnetic material is added to the plastic formulation to influence magnetic susceptibility without affecting the properties associated with the function of the plastic article. The material is preferably selected from a group consisting of magnetite, ferro-silicon and ferromagnetic particles (e. g. , iron filings). The amount or material can be varied in the range of between 0. 05% and 5% by weight of the plastic formulation. The plastic with altered magnetic susceptibility and a method separating that plastic from a waste stream are also disclosed.

A process and a structure is described for separating particles in a fluid medium based on a difference in settling velocity. The feed is introduced tangential into the separation zone. The tangential feed system includes a transition box to reduce flow velocity and disperse the slurry across the separator eliminating the efficiency losses associated with other classifiers that introduce feed directly into the separation chamber. This approach offers an improvement in process capacity and efficiency. The fluidization water is introduced to the separation chamber below a baffle plate that disperses the water across the base of the separator. The feed system may include baffles in the upper separation chamber, and a stilling well with an impact plate adjustable side walls and adjustable baffle plates to reduce flow velocity and disperse the slurry across the separator.

A top feed, wet drum magnetic separator capable of treating, removing tramp metal from the full flow discharge of a grinding mill having a feed box which provides overflow capacity, velocity break to minimize turbulence, and spread the slurry evenly across the drum surface. A flow transition is provided to the rotating drum surface. A fixed magnet assembly is supported inside the drum. Barrier walls contain the flow and a cover confines the flow over the drum. A partitioned product hopper collects metallic fragments separately from the bulk slurry flow. A spray bar is provided to clean the drum.
