摘要
探讨了几种表面活性剂对脂肪酸类捕收剂SH -1的增效作用和对黄麦岭磷矿常温浮选行为的影响。结果表明 :阴离子型表面活性剂十二烷基苯磺酸钠 (SDBS)、非离子型表面活性剂Tween -80对SH -1具有良好的增效作用 ,能明显改善磷矿的浮选特性。当矿浆温度为 1 2~ 2 0℃时 ,混合使用SH -1与SDBS和Tween -80 ,Hallimond管浮选的上浮率比单独使用SH -1提高 1 0 %~ 1 5%。
A synergism of some surfactants on the fatty acid collector SH-1 and effects of the synergism on the flotation performance of Huangmailing apatite ores are studied in this paper.Test results show that the anion surfactant sodium dodecyl benzene sulfonate (SDBS)、the non-ionic surfactant Tweeen-80,with better synergism on SH-1 can obviously improve flotation characteristics of apatite.When the temperature in flotation pulp is the 12~20℃,the recovery of the Hallimond flotation in using SH-1 together with SDBS、Tween-80 increases by 10%~15% respectively;ouer that in sing SH-1.
