煤用捕收剂的研究与应用现状

The Current Situation and Application of Research on Coal Collector

煤炭浮选是提高煤泥利用率,减少环境污染最有效的方法之一。然而,煤用捕收剂的捕收性能、选择性及其药剂用量等方面都是影响煤炭浮选效果的因素。文章从常用的非极性烃类油捕收剂、复合浮选药剂和联合用药三个方面论述了煤用捕收剂的研究现状、应用情况及其效果。

Coal flotation is one of the most effective ways to improve the utilization of coal slime and reduce environmental pollution.However,the collecting performance,the selectivity of collector and consumption of reagent for coal preparation etc.are the most important factors on impacting the effect of coal flotation.Through three aspects including the conventional non-polar hydrocarbon oil collector,complex flotation reagent and the combined use of reagent,this paper discusses the current situation of research,the use of coal collector and its effect.But the high reagent consumption and poor selectivity are still the major problem for coal flotation in China.The research of complex reagent has been a new trend in recent years,and achieved good results.The combined use of reagent as a new system not only can increase the activity of reagent,but also can improve the flotation index.So it has become another focus of the research of reagent.
