Tests of Sinterol Reagent in Flotation at OOO MMK

The flotation conditions for coal with different mineral content of the organic component are studied in the laboratory. The reagent protocol developed, which includes Sinterol modifier, is industrially tested. The results indicate that, if Sinterol is added at a rate of (1.0–3.0) ×10–3 kg/t of coal fines, the extraction of the coal’s combustible mass in the concentrate is increased ...
