초록
바나듐(V)은 은회색의 전이금속으로, 철강 제조 시, 소량만 첨가하여도 강도가 높아지고 충격과 마모에 강해 지는 특성을 가지고 있어, 고강도 합금의 원료로 많이 사용되고 있다. 또한, 최근에는 신재생 에너지의 저장장치에 적 합한 특성을 가지고 있는 것으로 알려진 바나듐 환원-산화 배터리의 주원료로서 해당 연구가 많이 진행되고 있다. 바 나듐은 현재 중국에서 저품위 무연탄 광석으로부터 회수하기 위한 선별기술이 많이 연구되고 있다. 대량의 광석 처리 가 가능한 자력선별 및 비중선별 등이 전처리 기술로서 많이 연구되고 있으며, 광물의 표면특성을 이용하는 부유선별 에 대한 연구도 이루어지고 있다. 우리나라에도 상당량의 바나듐이 부존되어 있는 것으로 보고되고 있으며, 수요확대 가 예상되는 바나듐 자원의 안정적인 확보를 위하여 이와 같은 선별기술의 개발이 시급한 실정이다.
Abstract
Vanadium (V) is a transition metal with a silver-gray color. It is commonly used in high-strength alloys because of its ability to improve impact and abrasion resistance, even when only a small amount is added. In recent years, there has been active research into vanadium reduction-oxidation flow batteries (VRFB), which are suitable for use in the development of storage devices for renewable energy applications. Separation and recovery of vanadium from low-grade stone coal ore is currently being investigated in China. Various pre-treatment processes have been studied, such as magnetic separation and gravity separation, that can be used to treat large quantities of ore, as well as flotation processing based on the surface characteristics of the minerals. There is an urgent need for the development of separation technologies to facilitate the self-sufficient extraction of vanadium resources present in Korea.
