Technological Study on Rare Earth Recovery from Rare Earth Sulfate Solution AITranslate
Abstract AITranslate
Study was made on the process for recovery of La and Ce rare earth metal elements from rare earth sulfate solution with sodium sulfate double salt method.The effects were investigated of reaction time,reaction temperature,sodium sulfate dosage and solution pH on rare earth recovery.The optimized technological conditions were obtained through single-factor condition experiments and orthogonal experiments as follows:reaction time of 120 s,reaction temperature of 65 ℃,sodium sulfate-rare earth mass ratio of 5.2∶1,and rare earth sulfate solution pH value of 2.0.Under the optimized conditions,the overall recovery of rare earth is more than 95%.The rare earth-sodium sulfate double salt is analyzed by XRD,and the result shows that high-purity lanthanide-sodium sulfate double salt was obtained.
