This study involves the characterization of po-22 tential resources in those mine residues, bearing in mind that its reprocessing can facilitate the en-23 vironmental remediation and rehabilitation activities which are underway at the site. X-Ray Fluo-24 rescence (XRF) and micro ()-XRF 2D mapping surveys were performed. Univariate and multivar-25 iate data analysis reveal that differences in compositions are mainly related with element concen-26 tration per type of waste. Image processing and clustering analysis allowed the recognition of dis-27 tinct elemental spatial distribution patterns. Some of these residues, although classified as archeo-28 logical-industrial heritage materials may present toxicity to the ecological environment and to hu-29 man health. This fact enhances, therefore, geoethical doubts regarding its remining and exploitabil-30 ity. In this context, a multi-criteria decision analysis considering two geoethical alternatives was 31 performed.GeoBioTec - Geobiociências, Geoengenharias e GeotecnologiasLIBPhys-UNLDCT - Departamento de Ciências da TerraRUNBarbosa, SofiaDias, António AlbertoFerraz, Ana Catarina VarandasAmaro, Sandra LourençoBrito, GraçaAlmeida, JoséPessanha, Sofia2022-06-01T22:27:15Z20212021-01-01T00:00:00Zinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/article16application/pdfhttp://hdl.handle.net/10362/139241engPURE: 44220992https://doi.org/10.3390/materproc2021005023info:eu-repo/semantics/openAccessreponame:Repositório Científico de Acesso Aberto de Portugal (Repositórios Cientìficos)instname:Agência para a Sociedade do Conhecimento (UMIC) - FCT - Sociedade da Informaçãoinstacron:RCAAP2024-03-11T05:16:34Zoai:run.unl.pt:10362/139241Portal AgregadorONGhttps://www.rcaap.pt/oai/openaireopendoar:71602024-03-20T03:49:22.455755Repositório Científico de Acesso Aberto de Portugal (Repositórios Cientìficos) - Agência para a Sociedade do Conhecimento (UMIC) - FCT - Sociedade da Informaçãofalse
