Research on the Recycling Process of Praseodymium-Neodymium Metal Polished Waste AITranslate
Abstract AITranslate
At room temperature(5~35 ℃),rare earths,fluorine and iron in Pr-Nd metal polished waste were recovered and recycled by screening,wet magnetic separation,acidification,oxalic acid precipitation and roasting.The obtained Pr-Nd oxide and Pr-Nd fluoride exhibit high purity,and the recovery rates of rare earths,fluorine,and iron are also high.The recovery rate of rare earths exceeds 96%,fluorine 90%,and iron 93%.The waste acid produced in the process of recovering the acid insolubles and the dust and washing water produced in the process of washing sieve oversize can be recycled in the treatment of the next batch.The whole process not only realizes the secondary resource utilization,but also produces no waste residue,saving the production costs and solving the problem of waste residue in environmental protection.The recovery and treatment method of Pr-Nd metal polished waste proposed by this process is simple and easy to operate and industrialize.
