报道了采用微乳化捕收剂浮选辉钼矿。比较了微乳化捕收剂与常规柴油的浮选性能。本研究是将纯辉钼矿物应用于改性哈利蒙德管的初步研究。pH试验结果表明，在柴油和微乳液存在下，pH=6时辉钼矿的回收率最高，分别达到93%和90%。在获得类似结果的情况下，观察到微乳液的消耗比柴油低。在微乳化捕收剂的浮选试验中，由于捕收剂用量过大，会导致不稳定气泡的形成，回收率略有下降。接触角测量结果表明，微乳化捕收剂对提高辉钼矿表面的疏水性更为有效。提出了一种吸附模型，认为微乳化捕收剂中存在的非离子表面活性剂形成了一个连续的双分子层，导致表面疏水性增加。本研究的完成证明了微乳化捕收剂在辉钼矿浮选中的可行性，试图简化辉钼矿浮选过程，特别是取代传统的高能耗、难储存的乳化捕收剂。
In this paper molybdenite flotation using microemulsified collector was reported. The flotation performance of microemulsified collector and conventional diesel was compared. This study is a preliminary investigation which uses pure molybdenite mineral in a modified Hallimond tube. The pH tests showed that the highest recovery of molybdenite in the presence of diesel and microemulsion was obtained at pH=6, reaching the recoveries of 93% and 90%, respectively. In the case of obtaining similar results, it was observed that the microemulsion consumption was lower in comparison to diesel. In the flotation tests with microemulsified collector the recovery slightly decreased because too large collector amount caused formation of more unstable bubbles. The contact angle measurements showed that the microemulsified collector was more effective for increasing the hydrophobicity of molybdenite surface. An adsorption model was proposed and it was suggested that the non-ionic surfactant present in the microemulsified collector formed a continuous bimolecular layer, resulting in the increased surface hydrophobicity. The accomplishment of this research demonstrated the viability of the use of microemulsified collector in molybdenite flotation, attempting to simplify the molybdenite flotation process, especially replace the conventional emulsified collector with high energy consumption and difficult storage.
