    Sammanfattning : Tungsten (W) is listed among the European Union (EU) critical raw materials (CRMs) for its supply risk and economic importance. Primarily, tungsten is produced from scheelite and wolframite mineral ores with 0.08-1.5% tungsten trioxide (WO3) grade. LÄS MER

  3. 2. Reprocessing historical tailings for possible remediation and recovery of critical metals and minerals : The Yxsjöberg case

    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mining waste; Historical tailings; Conceptual framework; Critical raw materials; Tungsten; Scheelite; Characterization; Mineral liberation analysis; Beneficiation; Reprocessing; Mineral Processing; Mineralteknik; Centrumbildning - Centrum för avancerad gruvteknik och metallurgi CAMM ; Centre - Centre for Advanced Mining Metallurgy CAMM ;

    Sammanfattning : With increasing consumption of primary mineral resources, the generation of mining wastes has also increased thus requiring the mining industry to address the growing environmental concerns. Waste rock and tailings are potential secondary sources of critical raw materials currently in short supply in the European Union, but also a source for environmental issues like acid mine drainage.
