In order to improve the flotation efficiency of high ash fine coal slime, flotation column was used to study the flotation of slime in Ertang Coal Preparation Plant. Firstly, industrial analysis and sieving test of the floating slime were carried out. The results show that the flotation efficiency is the best when the collector dosage is 400g / t and the amount of foaming agent is 600g / t, that is, the ratio of collector to foaming agent is 2: 3. In the premise to meet the requirements of coal ash, usually pulp concentration should be controlled as much as 60g / L below, in order to achieve the ideal sorting effect. The final index: 80.06% for clean coal production rate and 61.42% for perfect index flotation.
