摘　　要：为研究浮选药剂对贵州盘县煤炭浮选效果的影响,在工业分析和密度组成分析基础上,以<0.075 mm粒级含量为80%的煤样进行浮选试验,考察起泡剂、捕收剂、抑制剂对浮选效果的影响。试验结果表明:在起泡剂松醇油用量为100 g/t、捕收剂柴油用量为500 g/t、组合抑制剂X用量为1 500 g/t的条件下,累计精煤产率可达69.62%,精煤灰分为4.12%,浮选效果较好。In order to explore the effects of flotation regents on flotation result of the coal from Pan county of Guizhou province, based on the industrial analysis and density analysis, the flotation test was done on the coal sample which the content of less than 0. 075 mm particle is 80% , to study the effect of frother a- gent, collector and depressing agent on the flotation result. The test results show that ash content 4. 12% and concentrate yield being 69.62% of clean coal can be obtained by adding pine camphor oil 100 g/t as frother, diesel oil 500 g/t as collector and the amount of combined depressant X is 1 500 g/t.
