Abstract

Abstract: This paper focused on problems of fluctuation in flotation effect and waste in flotation agents caused by inhomogeneous addition and difficulty in quantitative control in frother amount in Dongpang Coal Preparation Plant. In this study, octanol was mixed with an emulsifier and water in a certain proportion to form emulsified frother, and thus the emulsified frother could be added smoothly and quantitatively. The emulsified frother was also able to disperse better in pulp. The effects of emulsified frother were evaluated by the index of flotation with different agents’ dosage in flotation tests. The results indicated that emulsified octanol formed the oil-in-water emulsion, making it fully disperse in pulp. The coal slime separation was significantly improved by using emulsified frother. At fixed amount of octanol, the production rate of clean coal was increased by 13.75% with constant ash. At equivalent floatation index, the rate of fuel saving reached 25 ~ 30%.
