Abstract

The extractive mining activity and the associated concentration and smelting industries produce different types of solid waste that are accumulated in dumps, flotation tailings dams and slag heaps. These mining waste have high contents of metals and semi-metals, which can cause an environmental risk if they reach the ground and drainage networks. Aware of this risk, administrations have been addressing the problem in recent years, in such a way that many of these tailing dams are being restored and sealed. In this field trip, we will focus on the area known as Adaro, within the Linares mining district. A review of the geology of the district and types of deposits, the mining techniques used and the concentration processes will be carried out. Based on this knowledge, the hydrogeochemical works carried out for the characterization of surface and groundwater in the studied sector are indicated, analyzing the condition they have evolved since the mining activity ended. The geophysical techniques used for the characterization of mining dams are also described and the effectiveness of the sealing carried out in some of these restored dams is evaluated.
