煤与化石树脂浮选分离的有效方法

Effective Separation of Fossil Resin from Coal by Flotation

通过采用多种表面活性剂处理矿浆的试验 ,证明褐煤腐植酸钠可选择性抑制煤 ,从而使得化石树脂与煤可以通过浮选方法有效分离。

Experiments conducted of several surfactants for pulp treatment, which verified that sodium salt of humic acid from brown coal can selectively depress coal. Effective separation of fossil resin from coal can thus be realized.
