Flocculation has been a successful method to improve the processing of fine valuable minerals [16]. In this process, flocs or aggregates are produced by long-chain water-soluble polymeric molecules. These polymers initially adsorb onto a mineral particle surface due to electrostatic forces, chemical interaction and/or hydrogen bonds.
