Metals that are mined in Spain include copper, nickel and even gold. Gold is used to coat jewellery because it doesn’t rust. It also looks attractive and improves the finish of an object. Because it doesn’t corrode when in contact with air, it protects the metal below it.

 The main metalwork industries in Spain are found in areas such as Cantabria, Asturias, Galicia and the Basque Country. This is because the major sources of coal are in places nearby, such as Asturias, Leon, Palencia and Valladolid. Important industries in Spain that use metal include the car industry – making cars and making parts for cars – and companies that make heavy machinery.
