Claims (4)
- 유기물이 질산 및 아질산이온으로 산화되어진 습식공정인산을 접촉하는 유기추출물로 부터의 환원성우라닐이온의 스트리핑에서 요소를 상기의 산화된 인산에 유기물이 인산을 접촉하기전에 가하는 단계로 특징 지어진 철이온의 효율을 유지하는 방법.
- 인산을 질산으로 산화시켜서 산에서 우라닐이온을 산출하며, 이 산을 질산염 및/혹은 아질산이온으로 오염시킴; 이 산화된 인산을 유기 추출물과 접촉하여서 유기물로 우라닐 이온을 추출하고; 이 유기물을 철이온을 함유한 스트리핑 수용액과 접촉하여서 유기물로부터 스트리핑용액으로 우라늄을 스트립하는 산화후 인산에 요소를 가하여서 질산염 및/혹은 아질산이온과 반응하도 록하는데 특징이 있는 습식공정인산으로부터 우라늄을 회수하는 방법.
- 산을 질산과 접촉시켜서 우라늄을 +6상태로 산화시키고, 인산을 질산염 및/혹은 아질산이온으로 오염시키고; 요소를 가하여 최소한 일부의 오염 이온으로 산에서 반응시키고; 이 산을 불용성 유기물과 접촉시켜서 그곳에서 산화된 우라늄을 추출하고; 상기 우라늄을 지닌 유기물을 용해된 환원 철이온을 지닌 스트리핑 용액과 접촉하는 단계로 특징지어진 습식 인산공정으로 부터 우라늄을 회수하는 방법.
- 용해된 환원이온이 철이온으로 구성되는 청구범위 3에 따르는 방법.※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.
