Using acrylamide/propylene oxide copolymers to dewater and densify mature fine tailings

•Novel PAM-gPPO flocculate and dewater MFTs effectively.•Shorter PPO grafts perform better than those with longer PPO grafts.•PAM-PPO 300(86:14) performed best for flocculation, dewatering and densification.•PAM-PPO have much lower molecular weights than commercial PAM flocculants. Adding hydrophobi...
