Tabas mines in Iran have coal sources which are suitable for use in metallurgy industries as coking coal. But the high sulfur content of this coal imposes severe limitations on its utilization as the sulfur oxide gases evolved from the combustion of high sulfur coals result in acid rains and corrosion of equipments. In this work, attempts have been made to reduce sulfur from high sulfur coal ofTabas by froth flotation. Laboratory tests were carried out in order to investigate the influence of various collectors, frothers, pyrite depressants and their consumption dosages on ash and sulfur reduction ofTabas coal. The use of kerosene as a collector and pine oil as a fr other has decreased ash and sulfur content of coal more than other collectors and frothers. Although use of sodium poly acrylic acid as a pyrite depressant improved the total recovery of coal concentrate but did not enhance the reduction of sulfur.
