IP signature of metallic particles: lessons learnt from field and laboratory experiments
Résumé
Past metallurgical sites and deposits account for a significant proportion of potentially contaminated sites in the European Union (EU): about 100,000 have been identified only in the North West regions of the EU. While recent wastes from sites still in operation are commonly recovered, this is not the case for old aggregated materials with a high content of ferrous (and other) metals, white and black slag, etc., which are considered to be sources of pollution and are costly to manage or dispose of. These sites could be considered as opportunities to recover large volumes of resources (metals, materials and land) using urban mining techniques if they were better characterized.
