| Resumo: | The evolution of sulfide wastes promotes acid mine drainage and phenomena of supergenic neoformation. These contribute to a secondary paragenesis, often dominated by salt efflorescences. These can be used as mineralogical indicators of reactivity conditions and of AMD potential. The present study shows the salt efflorescences that develop in the Spanish sector of the Iberian Pyrite Belt, as a result of the strong acid mine drainage observed in this region. The obtained results showed dominance of metallic sulfates. Depending on the proximity to the sulfide sources, there are different types of assemblages. Iron and cooper minerals dominate inside the mining areas, whereas magnesium sulfates occur more abundantly in the receiving river network |
