摘要：
The action of lignosulfonates, the coal-alkali reagent, sodium tripolyphosphate, and dispersing agent NF on aqueous suspensions of coal have been investigated. The properties of solutions of substance of different chemical natures and their influences on the properties of the coal surface (hydrophilicity), surface potential) and on the maximum amount of the solid phase in the system have been studied. The rheological characteristics of aqueous suspensions of coal with additions of SAAs have been determined.
