Method for separating rare-earth resource from rear-earth slag by virtue of supergravity

ActiveCN103451442ASolve the problem of environmental loadAchieving targeted enrichmentProcess efficiency improvementSlagCerium
The invention discloses a method for separating a rare-earth resource from rear-earth slag by virtue of supergravity, and the method comprises the following steps: step 1, cooling molten rare-earth slag within a temperature range of 1150-1300 DEG C at a cooling speed smaller than 2 DEG C / min to obtain thermally treated rare-earth slag; step 2, treating the thermally treated rare-earth slag by means of centrifugal gravitational separation. By virtue of centrifugal gravitational separation, a rare earth ore concentrate of which the cefluosil grade is 80%-93% can be obtained, and the recovery rate of rare earth in the rare-earth slag is as high as 85%-90%. In tailings, the main phase is calcium fluoride and barium fluorophlogopite containing rare earth, which can be used for replacing partial fluorite for recycling calcium fluoride, and meanwhile the tailings can be directly used as a raw material for extracting Sc2O3 and Eu2O3 by virtue of a wet method. The method disclosed by the invention has the advantages of realizing directional concentration of small and dispersed cefluosil in the rare-earth slag by virtue of supergravity, increasing the yield and quality of a product Ce2O3, and meanwhile recycling the fluorite, Sc2O3 and the Eu2O3 from the tailings. The method disclosed by the invention can be used for not only solving the environmental load problems caused by the rare-earth slag but also realizing comprehensive utilization of the rare-earth slag resources.
