Abstract

Tungsten is a resource that is widely used as a material for cemented carbide and special steel owing to its characteristics as a high-melting-point metal with excellent electrical and thermal conductivity, strong wear resistance and corrosion resistance, and low high-temperature thermal expansion coefficient. Demand is expected to increase as high-tech industries, such as robotics and aerospace engineering, develop in the current era of the Fourth Industrial Revolution. Tungsten minerals with economic development value are scheelite and wolframite, and approximately 73% exist in China, Austria, and Russia, while some are also buried in Sangdong mine, Korea. The interest in securing the resources and the processing technology development of tungsten should be constant, as the domestic supply is totally dependent on imports.

텅스텐은 전기전도도와 열전도도가 우수하고, 내마모성과 내식성이 강하며, 고온열팽창율이 낮은 고융점 금속이라는 특성으로 인해, 초경합금, 특수강 등의 재료로 많이 활용되고 있는 자원이다. 최근 4차 산업혁명 시대를 맞아 첨단로봇, 항공우주공학 분야와 같은 첨단산업이 발전함에 따라 그 수요가 증가될 것으로 예상된다. 경제적 개발 가치가 있는 텅스텐광은 회중석과 철망간중석이 있으며, 중국, 오스트리아, 러시아에 약 73%가 부존되어 있고, 국내에도 강원도 영월 상동지역에 매장되어 있는 것으로 확인되었다. 현재 텅스텐 자원은 전량 수입에 의존하고 있으며, 가격의 지속적인 상승과 원료 확보가 어려워 지속적인 관심을 가지고 기술 개발이 필요한 실정이다.
