Abstract

Summary

We describe here a tailings ponds’ potential to be a source of secondary raw minerals. This tailings pond was targeted as a study site because two mines, Aijala and Metsämonttu, from which the tailings are from, have been closed several decades ago, and therefore the tailings material might contain significant amounts of minerals which could be utilized with the modern processes. Geophysical measurements of gravity, magnetic, electromagnetic and electrical resistivity tomography were made to find out the dimensions and the inner structure of the tailings pond. By combining the results of geophysics and geochemistry sampling we estimated the mineral reserves and the amount of metals (Cu, Zn, Ag and Pb) within the tailings material. The Aijala tailings pond is one of the Finnish pilot areas of EU funded SMART GROUND project with focuses on the secondary raw material.
