高纯钍制备技术实验数据集

以包头或四川稀土矿生产过程中分离回收的纯度在95-99%的钍产品为原料，深入研究钍、稀土、铁、磷复杂体系中萃取分离钍的热力学和动力学机理，筛选出特效钍萃取剂N501，利用新型高效的萃取分离体系，采用“两步离心萃取法”制备高纯钍的工艺路线，多批次制得公斤级产品，使钍的纯度提高到99.99%以上。Using thorium products with a purity of 95–99% recovered and separated during the production of Baotou or Sichuan rare earth ores as raw materials, this study thoroughly investigated the thermodynamic and kinetic mechanisms of thorium extraction and separation in the complex system comprising thorium, rare earths, iron and phosphorus. A highly effective specific thorium extractant N501 was screened. Subsequently, a process route for preparing high-purity thorium was developed by employing the novel and efficient solvent extraction separation system and adopting the "two-step centrifugal extraction method". Multi-batch production yielded kilogram-scale products, and the purity of thorium was increased to over 99.99%.
