组合捕收剂在矿物表面的协同效应及其浮选应用综述

A Review on the Synergetic Effect of the Mixed Collectors on Mineral Surface and Its Application in Flotation

捕收剂按照一定比例组合后,形成的组合捕收剂的表面活性会显著优于单一组分。重点阐述了组合捕收剂在矿物表面产生协同效应的机理,主要包括共吸附、疏水端加长、促进吸附以及改善溶液环境等。针对组合捕收剂在难选矿石(菱锌矿、白钨矿、胶磷矿、钛铁矿、锂辉石等)的浮选分离方面的应用,分类介绍了阴离子捕收剂与阳离子捕收剂组合、阴离子捕收剂与其他阴离子捕收剂组合、阴离子捕收剂与螯合捕收剂组合、阴离子捕收剂与非离子型捕收剂组合等应用情况。

The mixed collectors have many unique properties prior to the single component. The ar-ticle elaborated the synergetic mechanisms of mixed collectors on the surface of minerals, such as, co - adsorption, extension of hydrophobic end, promoting adsorption and changing the solution en-vironment. In the terms of the application of the mixed collectors in flotation of refractory ores （smithsonite, scheelite, collophane, ilmenite and spodumene so on） , the mixed collectors pre-pared by anionic collector with cationic collector, anionic collector, chelating collector or non - ion-ic collector were introduced separately.
