CHARACTERIZATION OF SECONDARY RAW MATERIALS FROM MINE WASTE: A CASE STUDY FROM THE CAMPELLO MONTI NI±CU±CO±PGE MINING SITE (WESTERN ALPS, ITALY)

The present research is within the framework of Smart Ground project (G.A. 641988), which intends to foster resource recovery from different types of waste deposits by improving the availability and the accessibility of data and information on secondary raw materials (SRM) in the EU. The evaluation of the SRM potential requires the estimation of a number of factors which must include technical, economic and environmental considerations. A first factor is a thorough characterization of the waste material, that can be performed with different methodologies, depending on the waste typology. This issue has been addressed, within the project, on a number of pilot sites which include municipal solid waste landfills, industrial landfills and waste deposits related to the extractive industry. The present study shows the methodologies adopted for waste characterisation (sampling protocols and analysis), with the aim of evaluating the secondary raw materials potentiality from extractive waste facilities. In particular the study has been carried out on the extractive waste facilities of the Campello Monti Ni+Cu (±Co±PGE) mining site (Western Alps, Italy).
