Abstract: Described herein is combination of flocculants for flocculating fines solids in a suspension thereof. The combination includes: (a) an anionic polymer flocculant, and (b) a charged particle-polymer hybrid flocculant that includes charged core particles having an average size between about 150 nm and about 800 nm and each having a polymer polymerized thereon. The anionic polymer flocculant is to be added before, or at substantially the same time as, the charged particle-polymer hybrid flocculant.

Abstract: Described herein is a charged particle-polymer hybrid flocculant that includes charged particles having an average size between about 150 nm and about 800 nm and each having a polymer polymerized thereon. Charged particle-polymer hybrid flocculants are made by forming charged particles having an average size between about 150 nm and about 800 nm; and polymerizing a monomer on the charged particles to form the polymer. Fine solids are separated from a suspension thereof by adding the charged particle polymer hybrid to the suspension to produce floccules and a supernatant, and separating the produced floccules from the supernatant.
