초록
코발트와 니켈에 대한 수요가 증가함에 따라 다양한 자원으로부터 순도가 높은 상태로 이 금속들을 회수하는 것은 중요하다. 고순도 코발트와 니켈을 얻기 위해서는 다른 금속이온과의 분리가 필요하다. 본 총설에서는 순수한 코발트와 니켈용액을 얻을 수 있는 용매추출, 이온교환 및 침전법을 소개하고 비교하였다. 특히 용매추출에 대해서는 기존 공정의 장단점과 함께 공정조건을 조사하였다.
Abstract
Recovery of pure cobalt and nickel from diverse resources is important due to the increased demand for these metals. In order to get cobalt and nickel with high purity, separation of them from other metal ions is necessary. In this review, several methods to obtain pure cobalt or nickel solution, such as solvent extraction, ion exchange, precipitation were introduced and compared. For solvent extraction, the advantage and disadvantage of the separation process together with detailed process conditions were investigated.
