Abstract

Rare earth metal ore including rare-earth mineral has become a vital resource for high-tech industries. A small amount of rare-earth metal greatly improves properties of existing materials and enhances the developments of semiconductors, displays, high-precision and large-scale equipment. In Korea, the rare-earth metals considered to be not naturally occurring, however, reports suggest that there are economically feasible reserves of light rare-earth monazite and refractory metals such as tungsten, titanium, molybdenum, vanadium and metalloid elements tin and alkaline earth metal lithium. Therefore, development of empirical technologies that can effectively secure the domestic natural rare metals will be required.

희토류를 포함한 희유금속광은 첨단산업에 없어서는 안 될 필수자원으로, 적은 양만 사용하여도 기존재질의 물성특성을 크게 향상시킴으로, 반도체, Display, 첨단정밀 및 대형장비의 발전을 촉진시키는 계기가 되었다. 이러한 희유금속광의 경우 국내에는 부존되어 있지 않은 것으로 생각하고 있으나, 우리나라에도 경희토류인 모나자이트와 고융점 금속인 텅스텐, 티타늄, 몰리브덴과 반금속원소인 주석 그리고 알카리토금속인 리튬 등이 경제성 있는 규모로 부존되어 있는 것으로 보고되고 있다. 따라서 향후 국내부존 희유금속광을 효율적으로 확보할 수 있는 실증화 기술개발이 요구된다.
