  • INORGANIC PARTICLE POLYMER HYBRIDS AND USES THEREOF
    Publication number: 20180021700
    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.
    Type: Application
