摘　　要：以 BET为新型煤炭浮选药剂 ,用单矿物实验方法 ,分别对煤、煤系黄铁矿和煤矸石进行脱硫降灰的试验研究 ,并以煤炭常用浮选药剂 GF,FS2 0 2作试验对比 .结果表明 :尽管 BET的用量分别是 GF,FS2 0 2用量的 1 /1 0和 1 /1 0 0 ,但对黄铁矿、煤矸石等捕收性和选择性明显优于 GF,FS2 0 2 ,且不受 p H条件的影响 ;与其它 3种同系物 (AET,DET,HET)在脱硫降灰方面综合比较表明 ,BET的效果最好 ,具有用量少、选择性强等优点 ,是一种应用前景良好的煤炭浮选药剂 .The experimental research of desulphurizing and deashing from coal was carried out using the pure mineral test method and BET, a new reagent for coal floatation. The flotation effect of BET was compared with that of the commonly used reagents GF and FS202. The result shows that although the usage of BET is only 1/10 and 1/100 of GF and FS202 respectively, the collectability and selectivity for pyrite and coal gangue is obviously better than that of using GF and FS202. In addition, it will not be influenced by pH values. The BET is the best flotation reagent in comparison with the other three homologues (AET, DET, HET) because of its less usage and better selectivity. So it has a good application prospect.
