CHARACTERIZATION OF PAST METALLURGICAL RESIDUES USING GEOPHYSICAL IMAGING: A CASE STUDY OF DUFERCO SITE (BELGIUM)

Ancient metallurgical industries produced large amounts of residues which were typically deposited in heaps or tailing ponds. They were derived from mineral processing and metallurgical treatments that were not as efficient as the extraction processes used nowadays. On one hand, metallurgical wastes could represent a potential source of pollution, being an environmental and sanitary threat even centuries after the end of industrial activities. On the other hand, these residues may still contain valuable ferrous materials, non-ferrous metals and other elements considered as critical raw materia... Mehr ...
