Integrated assessment of environmental risk in AMD-affected mine waste: mineral...
Barroso, Ana; Valente, Teresa Maria Fernandes; Antunes, Isabel Margarida Horta Ribeiro; Cerqueira, Ângela; Gomes, Patrícia; Henriques, Renato F.The long-term environmental legacy of mining in sulfide-rich regions remains a critical concern due to the persistent generation of acid mine drainage (AMD) and the mobilization of potentially toxic elements (PTEs). This study presents a comprehensive, site-specific assessment of mine waste from two contrasting geochemical zones, Nuestra Señora del Carmen (NSC) and Volta Falsa (VF), within the historically unde...

Potential accumulation of strategic elements in mining dams : from remining to ...
Gomes, Patrícia; Valente, Teresa; Gazire Lemos, marianaABSTRACT: Raw materials, from oil to industrial minerals, are essential to the efficient functioning of the world economy. However, the extraction of base metals, for example, allowed the mobilization and accumulation of large amounts of reactive wastes, triggering critical environmental problems. The Iberian Pyrite Belt, one of the largest metallogenetic provinces in the world, is an example of this, as it pre...

Acid mine drainage and waste dispersion in legacy mining sites: an integrated a...
Barroso, Ana; Henriques, Renato; Cerqueira, Ângela; Gomes, Patrícia; Antunes, Isabel Margarida Horta Ribeiro; Marinho Reis, A. PaulaAbandoned mines pose environmental risks due to the accumulation of sulfide-rich waste, which generates acid mine drainage and produces fine-grained, unconsolidated materials that, when deposited on steep slopes, accelerate erosion and contaminant transport. This study assesses the environmental impact of the Trimpancho mining complex by integrating UAV-based photogrammetry, water analysis, and mine waste chara...
Advanced monitoring of abandoned mining sites with High-Resolution UAV Technology
Barroso, Ana Raquel; Henriques, Renato F.; Cerqueira, Ângela; Gomes, Patrícia; Antunes, Isabel Margarida Horta Ribeiro; Marinho Reis, A. Paula[Excerpt] In the past decade, unmanned aerial vehicles (UAVs), or drones, have become invaluable tools in the mining industry, supporting applications ranging from mineral exploration to environmental remediation. When equipped with high resolution image sensors, UAVs enable high spatial and temporal resolution surveying, making them particularly effective for monitoring abandoned mining sites. This paper prese...
Improved acidity estimation by integrating comprehensive dissolved metal(oid)s ...
Barroso, Ana Raquel; Cravotta III, Charles A.; Gomes, Patrícia; Antunes, Isabel Margarida Horta Ribeiro; Marinho Reis, A. PaulaThis study introduces a geochemical modeling approach using PHREEQC to improve the accuracy of acidity estimates in waters influenced by acid mine drainage (AMD). AMD, common in regions like the Iberian Pyrite Belt, is characterized by low pH and high concentrations of metals, sulfate and acidity. Conventional methods, such as net acidity, often underestimate actual acidity by excluding additional metal(oid) s ...
