| Abstract: | The results of screening raw ore showed that rare earth elements deposited in phosphate rock and they had positive relation with phosphate rock. A reverse flotation closed circuit consisting of one roughing, one cleaning and one scavenging stage was applied in the tests. Phosphate concentrate with P_2O_5 34.38%, MgO 0.28% and yield 63.13% could be got. |
