Description

습식과정의 인산에서 유라늄 추출방법
본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음
제1도는 분쇄된 철이 각 환원 스트리퍼에 가첨된 본 발명의 제1 실시예에 의한 우라늄 추출과정의 개략도,
제2도는 각 환원 스트리퍼로부터 부분적으로 산화된 스트리프산이 철상반응기를 통해서 순환되어 스트리퍼에 제거되는 본 발명의 제2 실시예에 의한 우라늄 추출구정의 개략도,
제3도는 두 환원 스트리퍼에 세 부분적으로 산화된 스트리프산이 각 스트리퍼의 철상반응기를 통해 순환하여 스티리퍼에 귀환된 본 발명의 제3 실시예에 의한 우라늄 추출과정의 개략도.

Claims (1)

  1. 농축우라늄 용매와 라피네이트산을 제공하기 위해 추출기를 통해서 우라늄을 함유한 산성용액을 통과하고, 철＋2가를 함유한 환원된 산을 생산하기 위해 철원소와 라피네이트산의 일부를 접촉시키는 것과, 환원된 스트리퍼시스템에서 환원된 산으로 농축우라늄 용매를 제거하는 단계를 포함하며, 산성에서 철의 일부가 부분산화물을 형성화도록 산화되는 곳에서 상기 부분산화물이 제거후 철＋3가의 실질적인 양을 포함하는 습식과정의 인산으로부터 우라늄을 추출하는 방법에 있어서, 셋째 단계에 형성된 부분산화물에 함유된 철＋3가가 철＋3가를 철＋2가로 환원시키기 위해 철원소와 접촉되는 것을 특징으로 하는 습식과정의 인산에서 우라늄 추출방법.
