| Abstract: | The combined process flow takingflotation as dominance to recover rare earth and niobiumcomprehensively from the strongly magnetic tailin gs isan effective process. Firstly,flotation is taken to separate out the rare earth concentrate with S1 andH205as combined collector. After that, t he flotation-magnetic separation-gravity separationcombinedprocess flow is u sed to obtain niobium from the tailings. Under the conditionthat the strongly m agnetic tailingscontain REO 8.5%, Nb2O50.125%, the grade of so obtained RE concentrate is REO 36.70%with therecovery of 57.34%; the grade of Nb conc entrate 1 is Nb2O51.66% and the grade of Nb concentrate 2is Nb2O5 0.59%;the total Nb recovery is 35.58%. |
