Interaction between PAM and kaolinite (0

Polyacrylamide (PAM) is a polymer flocculant that is commonly used in the flocculation and sedimentation process of coal tailings water. PAM can be divided into cationic polyacrylamide (CPAM), non-ionic polyacrylamide (NPAM), anionic polyacrylamide (APAM), and amphoteric polyacrylamide (AMPAM) according to the ionic type [2], [3].

Characterization and dewatering of fine coal tailings by dual-flocculant systems

Dual flocculation of coal tailings using anionic¨Cnonionic and nonionic¨Canionic combinations on settling rate (a) and turbidity (b). When the nonionic flocculant was added first followed by the anionic, settling rate increased rapidly especially at high concentrations but reversing the order of addition could not induce a significant change in the settling rate even at high polymer

Improved water recovery: A review of clay-rich tailings and saline water interactions

The review concludes by highlighting a number of research challenges, which include that: (i) aggregate structures from polymer-assisted flocculation that are optimal for settling cannot also be assumed to be so for sediment consolidation; (ii) there is scope for reducing longer-term tailings impacts by choosing novel processing routes in the fl...

The polymer adsorption increases with the following order: anionic PAM < nonionic PAM < cationic PAM []. Nonionic polyacrylamide adsorption on clay minerals is mainly caused by van der Waals forces [ 80 ], whereas cationic or anionic forms adsorb and bind soil particles through electrostatic forces or bridge formation between PAM charged moieties and solid surface group [ 1 , 80 ].
