Title: Beneficiation Experiment on an Apatite Rare Earth Ore
Abstract: An apatite rare earth ore constains a variety of rare earth minerals,mainly bastnaesite and monazite.The difficulty of beneficiation is fine dissemination size of rare earth minerals.According to the occurrence of rare earth in the ore and the mineral properties,the preliminary tests covering gravity separation,magnetic separation and floatation etc were conducted.The results indicate that the combinative process of floatation-magnetic separation can get a better index.In combination of floatation and high intensity separation process,rare earth concentrate with grade of 9.24% REO and recovery of 47.72% was obtained,and the apatite concentrate contains 2.71% REO with recovery 33.51% and P2O5 28.24% with recovery 85.32%.The total recovery of rare earth in both rare earth and apatite concentrate is 81.23%.
