Abstract:
      Process flow of rare earth extraction and separation was analyzed. Prediction accuracy and speed of ion component in rare earth extraction tank were investigated by QPSO optimization of ELM parameters. The production data of praseodymium in praseodymium/neodymium extraction of one factory was predicted and analyzed by this method. The results show that with advantages of fast speed and high precision, the method meets the requirement of production of rare earth extraction.
