ABSTRACT:
This invention relates to a process for the separation and recovery of particulate matter having an average diameter of about 1 micron or less through the use of aqueous hi-phase systems and the modification of the surface properties of the particulate matter through use of a surfactant to modify its tendency to selectively migrate to one phase of the bi-phase system.
