摘　　要：浮选精煤粒度过细会造成浮选消泡困难、浮选精煤水分高等问题,而合理的向浮选精煤中掺入粗颗粒,改善其粒度组成,有利于解决这些问题。通过试验论证了浮选精煤掺粗有利于浮选精煤消泡,并可有效降低浮选精煤水。The undersize clean coal brings about difficulty in froth breaking during flotation process and high water content of clean coal, so appropriate addition of some coarse coal into the flotation of clean coal can alter the size composition, which benefits to solve above problems. Experiment showed that the addition of coarse coal into the flotation of clean coal was helpful for froth breaking and decreasing the water content of clean coal.
