Abstract
본 발명에 관련된 스칸듐의 회수 방법은, 스칸듐과 철을 함유하는 용액(스칸듐 함유 용액)의 pH를 -0.5 이상 1 미만의 범위로 조정하고, 계속해서, pH 조정 후의 용액을 옥살산 용액 중에 첨가하여 옥살산스칸듐을 얻고, 그 옥살산스칸듐을 배소함으로써 산화스칸듐으로 한다.
Description
도 2는, 킬레이트 수지를 사용한 이온 교환 처리의 흐름을 나타내는 플로우도이다.
도 3은, 종래의 옥살산화 처리의 흐름을 나타내는 플로우도이다.
도 4는, 옥살산화 처리(본 발명)의 흐름을 나타내는 플로우도이다.
도 5는, 실시예 1, 2에서 얻어진 산화스칸듐에 관한 옥살산 첨가량에 대한 불순물 농도와 스칸듐 품위의 측정 결과를 나타내는 그래프도이다.
도 6은, 비교예 1에서 얻어진 산화스칸듐에 관한 옥살산 첨가량에 대한 불순물 농도와 스칸듐 품위의 측정 결과를 나타내는 그래프도이다.
도 7은, 산화스칸듐(pH 0, 0.5, 1.0의 스칸듐 함유 용액을 이용하여 생성)에 관한 옥살산 첨가량에 대한 불순물 농도와 스칸듐 품위의 측정 결과를 나타내는 그래프도이다.
