  • 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.
  • Can acrylamide based flocculants be used in oil sands extraction?
  • A representative example comes from the effluents (tailings) of oil sands extraction process that contain high solids organic-contaminated fine clays, where the use of conventional acrylamide-based flocculants does not meet the dewatering criteria needed by this industry. 3
  • Why are polymer flocculants used in water purification?
  • Therefore, in modern water purification technologies, polymer flocculants are increasingly used. Polymer flocculants cause the formation of large, coherent aggregates (so-called flocs) that settle in the solution. Synthetic polymers are highly effective flocculants at low dosages but have poor shear stability.
  • 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.
