摘　　要：为了解决众泰煤焦化公司浮选精煤灰分偏高的问题,采用浮选柱对浮选精煤进行精选试验。试验结果表明,浮选精煤经过精选后,灰分可由15.90%下降至9.94%。浮选精煤灰分改善后,重选部分的精煤产率可以得到有效提高,使综合精煤产率提高1.70%。在相同煤质情况下,每年可多生产精煤3.06万t,年增效益2815.2万元。In order to solve the problem of high ash content of flotation concentrate of Zongtai Coal Coking Company, flotation column was applied for cleaning experiment of flotation concentrate. The results showed that the ash content of flotation concentrate was reduced from 15.90% to 9. 94% after cleaning, and the yield of gravity concentrate was improved, and the total yield of clean coal improved by 1.70% , which would increase 3.06 million ton clean coals with a profit increment as high as 28. 152 million yuan per year.
