Abstract
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.
