Remote sensing-based detection of industrial recyclables in mining tailings

The sustainable use of natural geo-resources and the efficient use of valuable materials are gaining in importance worldwide. Against this background, anthropogenic deposits such as heaps and tailings are increasingly moving into the research focus as potential sources of raw materials. New strategies are necessary for the exploration and evaluation of the usable resource potential of corresponding old deposits. The ADRIANA project addresses this task using tailings from copper ore processing in Erdenet, Mongolia, as an example. In the project, remote sensing methods are innovatively combined with approaches from 3D deposit modelling to estimate the potential of the tailings as a deposit, and the technical and economic feasibility of extracting the contained valuable materials is examined.
