摘要
论述了选择性絮凝在太西煤分选中的应用研究,分别对分散剂用量、絮凝剂用量、矿浆浓度等各因素进行了单因素试验研究和正交试验研究,分析各因素对选择性絮凝的最优条件。结果表明,该法既可对极细粒煤泥进行分选,又可制备洁净燃料,对小于0.045 mm占68%的太西煤,可得灰分1.29%的精煤,产率在41.26%。
The principle of selective flocculation and the research of selective flocculation of Tai - Xi Coal separation are introduced in this paper,with fispersant dosage test,flocculant dosage test, concentration test and orthogonal test analysis the factors ＂ best arrange in pairs. The results show that this method can be used not Only for ultrafine coal slime separation but also for super - clean coal production and desulfurization. For Tai - Xi Coal whose fine particles of unden 0.045mm is 68% , the ash content of clean coal reach 1.29%, and recovery is 41.26%.
