Based on the comparative research on the applicability of floating effects of Dongpang Mine flotation reagents and Xingtai Mine ore flotation reagents, to improve the cleaned coal yield of Xiandewang mine's floating coal, and to clean ash, three other types of reagents were used to conduct the floating experiments, which showed that No.3 reagent yields the best results. Later on industrial experiments were conducted on No.3 reagent, which showed that the best system of medicament would be like this: collector 2 mL/s, foaming agent 4.25 mL/s, with cleaned coal yield of 68.22%, cleans ash of 9.62%,as well as improved floatation index of 62.01%, which can meet the needs of products.
