This site has the lowdown on mining in Spain:
Most of Spain’s mineral wealth is based on gold and base metal mining. Spain is an EU leader in terms of the value of minerals and metals produced. All uranium oxide production by the state-owned company, Enusa, at its Ciudad Rodrigo (Salamanca) mines, has now finally ceased. Spain has ceased massive-sulphide mining operations in the Iberian Pyrite Belt whilst operations at Reocín in the north of Spain have also been exhausted. Rio Narcea Gold Mines has become the only major copper and gold producer in Spain.
