| One of the most important industries in the country is the steel industry, which is the most important coke consumer in this industry. One of the important parts of the coke production is the appropriate quality of coal, which the ash content should be low according to the standards. In this research, an attempt was made to increase the recovery of the flotation unit and reduce the ash content of the Alborz-Sharghi coal washing plant. Three stages of flotation tests were designed. The amounts of kerosene as the collector and MIBC as the frother were set and the best result was obtained in the slurry solids concentration of 10 percent and the particle size of -50+500 microns, which decreased the ash content from 14.6% to 5.9% and increased the recovery from 49. 6% to 74.6%. After applying the circulating load, the recovery and ash both decreased and the total recovery reached 69.9% and the ash of the final product reached 18.6%. | ||
