摘要

High-sulfur coal in this research is the sample from Fuxian, Shanxi Province. It studiesrndesulfurization and ash reduction research of Fuxian coal by the flotation method. This paperrndiscussed the ash, sulfur, disseminated state of pyrite sulfur and floatability of sulfur in raw coal,rnand carried on the experiment of desulfurization and ash reduction by flotation. It investigatedrnmainly ball milling, ultrasonic pretreatment, coal slurry concentration, collector dosage, blowingrnagent dosage, inhibitor dosage and different agents which affected the result of desulfurization andrnash reduction. From the test of desulfurization and ash reduction, we can know the ash of raw coalrnis 33.32% and sulfur is 3.31%, but after ultrasonic pretreatment, the sulfur is 1.95% and the ash isrn16.52%, so ball milling and ultrasonic pretreatment on raw coal are better than conventionalrnflotation. The results show that it is beneficial to expand the way of desulfurization and ashrnreduction through proper ultrasonic pretreatment on high-sulfur coal.
