Mixed cationic/anionic surfactants are generating increasing attention as effective collectors during the flotation of muscovite, feldspar and spodumene ores. Many papers have been published focusing on the flotation mechanisms of these valuable minerals. However, the depression mechanisms on gangue minerals such as quartz have rarely been reported. In this study, mixed dodecylamine (DDA)/sodium oleate...
The performance of the mixed dodecylamine chloride (DDA)/octanol (OCT) surfactants on muscovite flotation was investigated using flotation tests, and their adsorption mechanisms on muscovite and air/water interface were clarified using contact angle measurement, surface tension and molecular dynamics (MD) simulations. The flotation results indicate that the recovery of muscovite rapidly decreases...
