Abstract

본 발명에 따른 산화몰리브덴 정광에 함유된 불순물의 침출방법은 염화암모늄, 염화나트륨 및 염산이 포함된 제1 침출액, 염화암모늄, 염화칼슘 및 염산이 포함된 제2 침출액 및 염화암모늄, 염화나트륨, 염화칼슘 및 염산이 포함된 제3 침출액으로 이루어진 군 중에서 선택되는 어느 하나의 침출액을 사용하여 산화몰리브덴 정광의 불순물을 침출하는 단계를 포함하는 것을 특징으로 한다. 본 발명에 따른 침출방법에 의하면, 침출이 종료된 후 산화몰리브덴 정광은 대부분이 고체상태로 존재하므로, 침출액 중 용해되어 있는 몰리브덴을 회수하기 위한 공정이 불필요하거나 최소화되는 효과가 있다. 또한, 본 발명에 따른 침출방법에 의하면, 염화암모늄의 사용량이 감소하므로 방류되는 폐수 중 총 질소량을 감소시키는 효과가 있으므로 수질개선의 효과를 기대할 수 있다.
