Abstract
La mina de Lousal ha sido uno de los principales focos de atención en la zona sur de Portugal por su intensa actividad minera desarrollada desde principios del siglo pasado. Actualmente presenta graves problemas medioambientales debido a la contaminación generada por los residuos mineros que se encuentran expuestos en superficie desencadenando la formación de Drenaje Ácido de Minas que altera y degrada el medio y los ecosistemas colindantes. El presente trabajo desarrolla un estudio de caracterización geoquímica y mineralógica de muestras de suelo localizadas en la zona noreste de la mina.
The Lousal mine has been one of the main focuses of attention in southern Portugal due to its intense mining activity since the beginning of the last century. It currently presents serious environmental problems due to the pollution generated by mining waste exposed on the surface, triggering the formation of Acid Mine Drainage which alters and degrades the environment and surrounding ecosystems. In the present work, a geochemical and mineralogical characterization study of soil samples located in the northeast area of the mine is developed.
