• Geochemical Characterization of Historical W, Cu and F

  Beryllium, Cu, F, and Zn has high potential to be released to the surrounding environment from the Smaltjärnen Repository, while W, Bi and Sn are relatively stable in the tailings. Most of the scheelite is intact and re-mining could, therefore, be a suitable remediation method that would both reduce the environmental impact and simultaneously . Tailings Abandoned Colomac Mine - Govtailings, while the pattern of metals in the gut contents resembled that of Paddle Lake caribou faecal material, probably due to high sodium content. When compared to Colomac caribou faecal pellets, the moose faecal pellets showed higher proportions of zinc, strontium and magnesium which could reflect the different metal content in insoluble material on moose browse.
