Study of the rheological properties of the plasticizer to obtain a coal-water slurry

Abstract

The article presents the results of the study of the impact of plasticizers on the stability of coal-water suspensions obtained from Shubarkul coal slurries. As part of the task to determine the optimal reagent-plasticizer, an experimental installationwas developed. Fuel oil, gelatin, sodium humate were used as reagents-plasticizers. The process of enrichment of coal slurries of Shubarkul Deposit was studied; it is shown that the best results are obtained with the use of sodium humate. The use of sodium humate as a plasticizer makes it possible to create coal-water suspensions with a spatial network-like structure that do not delaminate for a long time.
