摘　　要：介绍了选择性双向絮凝分选原理及使用该技术分选极细粒煤泥的试验研究 ,讨论了煤样粒度、矿浆浓度、矿浆pH值、矿浆搅拌强度对选择性双向絮凝分选效果的影响 ,结果表明 ,上述因素对改善选择性双向絮凝分选极细粒煤泥效果有较大的作用 ,并提出了提高选择性双向絮凝分选效果的途径。The principle of selective bi-direction flocculation and the experiment research on selective bi-direction flocculation of ultra-fine coal separation is described in the paper and the effect of particle size of coal sample, concentration and pH of pulp as well as pulp mixing intension on selective bi-direction flocculation is also discussed. The test results show that the factors stated serve an important function in improving the effectiveness of ultra-fine coal separation by selective bi-direction flocculation. An approach made to further improving performance of the technology is put forward as well.
