5. Extraction of Backfilled Tailings in the Dannemora Mine – Economic Potential and Rock Stability Assessment
University essay from Uppsala universitet/Institutionen för geovetenskaperAbstract : The cut-off grade determines what rock mass are economic to mine. At the Dannemora mine, in eastern Bergslagen, Sweden, previously processed ore generated tailings (enrichment sand) with an iron content of 21-22 % that was backfilled into large open bodies (stopes) in the mine between 2013-2015.
