Abstract
This paper studies the effect of using cationic/mixed anionic collectors in the practical application of quartz sand flotation. The combined use of Dodecylamine(DDA)/sodium oleate(NaOL)/sodium dodecyl sulfonate(SDS) is the innovative point of this paper. This experiment used quartz sand from Hanzhong, Shaanxi Province, China. The results showed that the combined use of DDA, NaOL and SDS was better than the single use. Using DDA/NaOL/SDS mixed collector, the removal efficiency of Al2O3 can reach 75.1%, compared with DDA/NaOL mixed collector, the purification effect of Al2O3 can be increased by 11.1%. Compared with DDA/SDS mixed collector, the use of this mixed collector can greatly improve the purification effect and recovery rate. And the quartz concentrate has a good recovery rate in practical application.
