  • What is a polymer flocculant?
  • Among the synthetic polymer flocculants, the most important is water-soluble polyacrylamide (PAM)—a non-ionic, amorphous polymer which can be modified to ionic form in the copolymerization process [ 8, 9, 10 ]. The acrylamide monomer can be used for grafting or crosslinking of other type of polymers.
  • Are nanocomposite flocculants based on synthetic polymers?
  • Most of the literature presents, however, nanocomposite flocculants based on synthetic polymers [ 230, 231 ]. An example of nanocomposite with using both synthetic and natural polymer is mentioned earlier graft copolymer of polyacrylamide/xanthan gum with silica nanoparticles [ 113, 114]
  • How effective are natural polymeric flocculants?
  • The effectiveness of natural polymeric flocculants such as starch, amylose, amylopectin, gelatine, and alginate is well known. The latest developments in polymeric flocculants are artificial polymers. The most widely used artificial polymer flocculants are non-ionic polyacrylamides and their derivatives [ 9 ].
  • Which nonionic polymeric flocculants are used in the mining industry?
  • PAM and polyethene oxide are two of the most prevalent nonionic polymeric flocculants used in the mining industry.
