Development of a Technology for Chemical Refinement of High-Ash Graphite Flotation Concentrates From the Taskazgan Deposit

In this article, the concentrate obtained from a graphite sample of the Taskazgan deposit was processed using thermal and hydrochemical methods. Optimal parameters for the removal of harmful impurities from the flotation concentrate were determined. As a result, using combined methods, the carbon content in the graphite concentrate reached 92.8%, with an ash content of 0.3%. According to the conducted research, the possibility of extracting a high-quality graphite concentrate based on the combined enrichment scheme was established.
