본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음

Claims (4)

  1. 교반조건하에서 무기산(인산)상과 추출제를 함유하는 유기상을 접촉시켜 제1단계로 케스케이드 형태의 n단을 구성하는 추출단위의 각 추출단에서 시간 T1동안 인산 및 추출제를 함유하는 상기 두 상간의 접촉표면을 증가시키기 위해 적어도 5000Seconds-1의 전단계수에 상응하는 기계적 전단작용세기에 따르게 함으로써 에멀션을 제조하고 에멀션후, 제2단계로 시간 T2에서 급작스럽게 분쇄함을 특징으로 하는 것으로써 상기 두단계를 수행하는데 요구되는 시간의 합 T1+T2가 20분이하인 알킬피로인산에 의한 인산용액중의 우라늄 추출방법.
  2. 제1항에 있어서, 추출단위의 단수 n이 2-20으로 구성됨을 특징으로 하는 우라늄 추출방법.
  3. 제1항에 있어서, 추출단위가 단일단으로 구성됨을 특징으로 하는 우라늄 추출방법.
  4. 제1항 내지 제3항중 어느 한항에 있어서 전단계수를 5000-50000Seconds-1이나 10000-25000Seconds-1에서 선택함을 특징으로 하는 우라늄 추출방법.
    ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.
