ABSTRACT:
A method for the recovery of microfine suspended particles from a suspension medium, characterized by subjecting a polymeric monomer suspended in a suspension medium to suspension polymerization thereby forming microfine globular particles in the suspension solution, adding microfine water-insoluble particles to said suspension solution of microfine globular particles thereby inducing cohesion of said microfine globular particles, and separating said microfine globular particles in the form of an aggregate from said suspension solution filtration.
