It is intended, within the scope of the project, to observe the conditions of contamination by Potentially Toxic Elements in the sediments, both dissolved and suspended forms in the water column, in order to carry out a general characterization of the mining system, based on the nature and amounts of the contaminating elements, as well as the conditions of acidification occurring on sediments present in the environment that surrounds the mining area. The aim is to understand, based on the existing conditions, the best environmental remediation technology to be applied in the region.porCaveira MineSedimentsEnvironmentRemediationIberian Pyritic BeltMina de CaveiraSedimentosMeio ambienteRemediaçãoFaixa Piritosa Ibéricaconference paper
