Research project Reminigplus

Mining activities and ore processing generate huge quantities of mine tailings, which still contain significant amounts of valuable metals. In previous projects, a pilot plant for bioleaching and the extraction of valuable metals was constructed. Within the ReMiningPlus project, the process technology will be enhanced to establish a holistic process, which comprises the recovery of valuable metals, such as In, Zn, Pb, Cu and Co, the reuse of the solid material (e.g. as building material) as well as the immobilization of hazardous elements. The pilot plant is semi-mobile and will be located close to

Freiberg at the mine tailing “Davidschachthalde”. Due to the unique concept, it can also be used for comparable studies at any other location. The ReMiningPlus project demonstrates an innovative solution for the remediation of mine tailings. The pilot facility delivers detailed process data, which enable an assessment of economic and environmental aspects (life cycle assessment). Furthermore, the Ore Mountains region benefits from the project by gaining know-how about the development of pioneering technologies and the construction of advanced pilot faclities for the remediation of mining residues.

What is the task of the GEOPARK at ReMiningPlus?

The GEOPARK would like to increase the awareness of raw materials and their sustainable use. For this purpose, we are developing an environmental education concept that will include offers such as excursions and one-day events for various target groups.

In addition, a website or app is being developed to provide information on mining-related topics. Visitors will be able to find out about the results of the research project on two information boards.

The following partners are working to implement the project goals::

  • G.E.O.S. Ingenieurgesellschaft mbH
  • Helmholtz Institut für Ressourcentechnologie Freiberg
  • SAXONIA Standortentw.- & -verwaltungsgesellschaft mbH
  • Freiberg Institut für vernetzte Energieautarkie
  • GEOPARK Sachsens Mitte e.V.
  • Kaden & Döring OHG
