随着我国原生煤泥量上升致使浮选量加大，选择一种药耗低、效果好、成本低的浮选药剂是提高经济效益的有效途径。本文所使用的复合药剂通过红外光谱分析，具有捕收和起泡的双重功能。随后对常规浮选药剂和新型复合药剂进行了试验研究及对比，发现新型复合药剂在药耗、浮选速度和浮选效果方面都比常规药剂好，且在浮选精煤产率、浮选完善指标和可燃体回收率方面也比较理想。

Following the improvement in mining technology,more native slime are generaG ted,resulting in the increased work load of flotation process.Thus,it will be an effective way for a preparation plant to improve its economic performance by use of flotation reagent characterized by high performance,low cost and low consumption.It was found by infrared spectroscopy that the compound reagent analyzed in this paper had a dual function of collecting and foaming.The reG sults of a series of contrastive experiments between the new composite and the conventional flotaG tion reagent showed that the new agent had better performancein terms of agent consumption and flotation speed than conventional agent.In addition,the new flotation agent showed more ideal cleaned coal yield and flotation perfection index,as well as recovery rate of combustible materials.
