Experimental Study on Lepidolite Flotation with Anion-cation Combined Collectors

Abstract

Abstract

Combined collector has synergistic effect and can improve selectivity and recovery in mineral flotation.Taking a lepidolite ore as research object,this paper mainly studied influence of collector's combination,combination ratio and reagent dosage on lepidolite concentrate grade and recovery.The best anion-cation combined collector was prepared by anionic collector oxidized paraffin soap and cationic collector dodecylamine with a combination ratio of 4∶1.It was demonstrated that the combined collector possessed a better flotation performance,through which a lepidolite concentrate containing 3.77% Li2O with a recovery of 72.58% was obtained.
