Mine dumps the abundant by-products of centuries of mining in Europe have potential to become sources of a wide range of metals and minerals. Despite their variable volumes and the geometallurgical challenges involved, they are a raw material resource to include among other, not least in the context of the present societal demand to increase recycling. Until the mid-1900s the applications and therefore the markets for many metals were limited. Additionally, many were difficult to identify, and thus often missed. In numerous mining districts this resulted in rocks hosting such metals to end up as waste, that is, on the mine dumps. The present pilot project is aimed at testing the potential for such secondary resources in the classic and ancient Bergslagen ore province in south central Sweden, with a special focus on metals presently identified as "critical" for industry. The Bergslagen province, with its 1000-year-history of mining is a suitable testing ground to find out what may actually be out there. Results so far include the detection and mineralogical characterisation of variable amounts of precious and critical as well as base metal minerals, along with the main ore commodity in many old mining fields.
