摘要
通过接触角测量和红外线检测分析,论述了抑制剂在浮选过程中的作用机理;试验研究了不同类型抑制剂对阳泉无烟煤高灰煤泥的浮选效果;结果表明,使用变性淀粉作为抑制剂时,精煤灰分降低最为明显,当用量为1 kg/t时,得到浮选精煤产率为64.74%,精煤灰分为8.7%。
By contact-angle measurement and ultrared analysis,the reaction mechanism of a depressant in coal flotation expounded;for flotation of Yangquan high-ash anthracite slime,experimental study conducted with different depressant to compare their flotation performance;modified starch was found to give remarkable ash reduction effect,in that at dosage of 1 kg/t,the concentrate ash being 8.7%at 64.74%yield.
