Abstract

Using fluidized bed under the action of high fluoride on simulation of jiangxi rare rare earth smelting waste water to remove the test. Articles by controlling the F/Ca, change CaF2 (AR) particle size and so on has carried on the related experiment, and the output of the crystal were characterized, and the experimental results show that the change of CaF2 (AR) particle size effect on fluoride in effect is not big, but when the control F/Ca is 0.6, namely the F - 300 mg/L, Ca2 + is 500 mg/L when can achieve a certain amount of fluoride in effect, the F - concentration drops to about 10 mg/L. Conclusion: effective control in the fluidized bed reaction conditions conducive to Ca2 +, as well as the combination of F - and CaF2 crystal growth at the same time to achieve the ideal effect of fluoride.
