摘　　要：介绍了选择性双向絮凝分选原理及用选择性双向絮凝技术分选极细粒煤的试验研究 ,结果表明 ,该法可对极细粒煤泥进行分选 ,通过采取多次分选的方式 ,可制得灰分在 3%以下的洁净燃料。The paper reports the principle governing selective bi-direction flocculation and experimental research on selective bi-direction flocculation of ultra-fine coal in separation. The results indicate that this method can be used for cleaning coal slime containing ultra-fine coal. Super-clean fuel with ash less than 3% can be produced in case that multi-separation is used.
