The aim is to increase knowledge about geological, mineralogical, geochemical and chemical interacting processes in order to assess environmental impacts and potential environmental risks related to the handling and utilization of sulfide-bearing rock.
"The goal is that materials can be used as a resource and not stored in landfill. This projects have a great value for the Swedish Transport Administration and society as it concerns both the management of natural resources and the economy," says Thomas Dalmalm at the Swedish Transport Administration.
The new knowledge of interacting processes will be used to develop predictive methods that address environmental impacts and risks in future projects.
The new knowledge is also expected to be used for geochemical classification of excavated sulfide-bearing materials. The overall aim is to provide better resource management and a more circular economy.
"The research is in line with the government's ambitions for resource-efficient use of rock masses," says Project Manager Lena Alakangas Professor in Applied Geochemistry.
