【 摘 要 】

The interaction with modifying substances of flocculants on the basis of polyacrylamide has been investigated. The main characteristics of the modified flocculants were studied. Their advantage over unmodified flocculants in the process of cleaning flotation tailings is shown. According to the results of the research, the molecular weight of the modified polymer was 25 times more than the initial matrix sample. The volume characteristics of macromolecules such as the average distance between the ends of the molecules and the hydrodynamic volume occupied by the unit mass of the macromolecule were studied. The possibility of using modified flocculants for cleaning flotation tailings during coal enrichment has been studied.
