le and Peru are rich in minerals. In fact, the two countries are the worlds biggest producers of copper, gold

and silver. Siemens Chile and Siemens Peru support globally active copper producers in the two countries with new innovations and

varied range of services. 3The demand for copper is often seen as an indicator for the stabili- ty of an

economy. In emerging countries, this increased demand is usu- ally sign of the advancement of the middle class; better standard

of living that is expressed in higher demand for consumer goods and an expansion of the local infrastructure. Copper is used in number of areas: to transmit electricity and for communications, for consumer goods and computers, in modes of trans-port, for building infrastructure, industry motors and much more. Chile is home to state-owned Codelco (Corporacin Nacional del Cobre de Chile), the worlds largest copper pro-ducer, which is responsible for about 1 percent of the countrys public revenue. In 2, Codelco excavated around 1.8 million tons of copper. Codelco operates total of six mines in Chile, including the Chuquicamata mine, about 1 km north of the city of Calama. Chuquicamata was opened in 1, and today it is the worlds largest open-pit mine. Around 7 km south of Santiago, in Sewell, is El Teniente, the worlds largest underground mine: the total length of the mines road network is 2,4 km. Further Codelco mines are Radomiro Tomic (in operation since , El Salvador and Andina (in operation since , Gaby (in operation since as well as Ministro Hales (begin of operation in . Chris Vains from Siemens Industry Automation stresses the necessity for mining companies to continuously invest in new technologies to satisfy demand for raw materials. By doing so they can ensure highest pro-ductivity, efficiency and dependability. Continuous innovation is also necessary given the fact that copper mines in the Andes are exposed to ex-treme conditions: severe frost and meter
