摘要
利用选择性聚团法对平顶山尾煤进行脱灰分选 ,加入分散剂后 ,在一定程度上可降低超细精煤的灰分。选择六偏磷酸钠、硅酸钠、腐植酸钠、木素磺酸钙、碳酸钠、糊精 6种分散剂进行了应用实验 ;并通过测量矿浆的ZETA电位分析了这些分散剂的作用机理。
Selective agglomeration flotation process was applied for de ashing of tailing from Pingdingshan.. Experiment with six dispersants denoted that ash content can be lowered down in certain extent. The mechanism of dispersant was analyzed by Zeta potential measurement.
