Approach to recover strategic metals from brines [PDF]
, 1981 The objective of the proposed research is to evaluate hypersaline brines from geothermal sources and salt domes as possible sources for some strategic metals. This research is suggested because several previous analyses of brine from geothermal wells in the Imperial Valley, California, and from Gulf Coast salt domes, indicate near commercial values for

Chemical Analyses of Geothermal Waters and Strategic Petroleum Reserve Brines for Strategic and Precious Metals [PDF]
, 1983 Water form seven hydrothermal-geothermal, one geopressured-geothermal, and six Strategic Petroleum Reserve wells have been surveyed for twelve metals of special strategic and economic importance using trace chemical analysis techniques. The elements sought were Cr, Co, Mn, Ta, Sn, V, Nb, Li, Sr, Pt, Au, and Ag. Platinum was found at a concentration of ~

Rare Metal as a National Strategic Material [PDF]
Journal of Korean Powder Metallurgy Institute, 2009 희유금속(稀有金屬, rare metal)은 1 지각 내에 존 재량이 적거나 추출이 어려운 금속자원중 현재 산업 적 수요가 있고 향후 수요 신장이 예상되는 금속원 소, 2 극소수의 국가에 매장과 생산이 편재되어 있 거나 특정국에서 전량을 수입해 공급에 위험성이 있 는 금속원소로 정의하며 국내에서는 56개 원소를 희 유금속으로 분류하고 있다. 이는 학술적 기준이 아닌 산업적 기준이어서 희유 금속으로 분류되는 원소는 국가 혹은 시대에 따라 대 상이 변화될 수 있는데, Rare Metal Hand Book은 48개 원소, 미국은 41개 원소, 그리고 일본은 55개 원소로 정의하고 있다.

Biofibrous nanomaterials for extracting strategic metal ions from water
Exploration, 2022 AbstractStrategic metals play an indispensable role in the related industries. Their extraction and recovery from water are of great significance due to both their rapid consumption and environmental concern. Biofibrous nanomaterials have shown great advantages in capturing metal ions from water. Recent progress in extraction of typical strategic metal
