本文提出了一种新的两步法沉淀生产黄饼工艺，解决了传统二步法沉淀铀所产生的一系列问题。在除铁的同时可除去部分硫酸根，不仅固液分离容易，而且还有效地利用了铁沉淀过程中所产生的硫酸，此外还使溶液中铀浓度提高。新工艺投资省、操作简单、消耗低，它比用离子交换法及溶剂萃取法提纯并最终制取黄饼的工艺更具有竞争力。 In this paper, a new two-step precipitation process of yellow cake is proposed to solve a series of problems caused by traditional two-step precipitation of uranium. In addition to iron can be removed at the same time part of the sulfate, not only solid-liquid separation easy, but also effectively use the iron precipitation process generated sulfuric acid, in addition to the solution uranium concentration increased. The new process investment province, simple operation, low consumption, it is more than ion exchange and solvent extraction purification and the final preparation of yellow cake process more competitive.
