摘　　要：介绍了用选择性絮凝浮选方法对某高灰极难选煤泥进行了分选试验研究，考察了团聚剂用量及种类、搅拌调浆浓度、分散剂用量等工艺因素对浮选的影响，获得了优于常规浮选的分选效果。Experimental study on selective flocculation flotation of high ash and difficult floatable coal has been carried out. And the technological factors,such as aggregation reagent type and dose, pulp concentration of agitation, and dispersant dose, are also examined. The conclusion shows that the separation result of this technology is superior to conventional one.
