Collecting agent for coal flotation RS-231 (Reasin) allows you to efficiently extract coal of all grades (KS, T, SS) with a high recovery rate of up to 96%. High extraction results and enrichment quality can be achieved with RS-231 dosage in the range from 100 to 150 grams per ton of coal, the average coal extraction is above 90%, while the moisture content of the flotation concentrate decreases, its ash content decreases with a significant increase in the ash content of flotation waste. Thus, taking into account the increase of flotation concentrate yield and the improvement of its quality, the consumption of flotation reagent per ton of finished product is significantly lower compared to existing counterparts, whereas RS-231 is much more cost effective.
