Abstract

In the present work efforts were made to enhance the recovery of cleans with reduced ash percent using soap-light diesel oil emulsion as collector in coal flotation. Flotation tests were carried out at plant condition using diesel oil as collector and soap-light diesel oil emulsion as collector at plant conditions. From the results it is inferred that soaplight diesel oil emulsion recovered 80.4% of the cleans by weight along with 14.82% ash of cleans by nullifying the use of frother in flotation experiments whereas diesel oil recovered 37.4% of the cleans by weight along with 12.21% of cleans ash. Conclusively soap-light diesel oil emulsion enhanced the efficiency of flotation.
