Flocculating oil sands tailings with dual anionic/cationic polymers: Dose and charge density effects
The Canadian Journal of Chemical Engineering, Volume 102, Issue 1, Page 88-101, January 2024.Abstract A two‐step process, with anionic hydrolyzed polyacrylamide (HPAM) and cationic poly(vinylbenzyl trimethylammonium chloride) (PVBTMAC), was used to flocculate oil sands mature fine tailings (MFT). The charge density of HPAM and the dosages of HPAM and PVBTMAC were varied to maximize the dewatering of MFT and minimize the turbidity of the ...
