  • Can polyanion reduce cationic flocculants?
  • According to ref. , even the inclusion of a little polyanion can considerably reduce the flocculating action of cationic flocculants. This suppressive effect can be explained by a decrease in the effective collision radius induced by the swollen polymer coil shrinking because of an oppositely charged polymer link.
  • Is cationic Pam effective in flocculation?
  • The success of anionic and cationic PAM in flocculation can be related to particle charges that allow for particle flocculation with polymers. Non-ionic PAM was shown to be ineffective at flocculating tailing particles. The ionicity of the polymer appears to be highly relevant here, based on the results.
  • Which polymers are used as flocculants?
  • As flocculants, we used two commercial polymers manufactured by BASF, Alclar 662® and Magnafloc LT7990®, referred to as AC 662 and MF LT7990. Alclar 662 is a anionic synthetic flocculant specific for red mud. It is based on PAMs with very high molecular weight, and pH = 7 for 1% solution at 25 °C. It is
