Siemens has secured an order to maintain and overhaul technical equipment at the Andina copper mine. This service agreement with the world’s largest copper producer will run for five years. The deal takes the form of a long-term partnership, under the terms of which the work done is billed according to agreed indicators such as production volume, plant availability, safety and compliance with environmental specifications. The services are provided according to the risk-based maintenance concept which Codelco introduced at Andina at the beginning of this year.

“This new order demonstrates our customer’s confidence in Siemens as a provider of sustainable service solutions,” said Dirk Hoke, CEO, Siemens Customer Services Division. “It further reinforces the long-standing successful cooperation between Siemens and Codelco.”

In 2011, Codelco turned out roughly 1.8 million metric tons (mt) of copper, about 11% of the global total, making it the largest producer of copper in the world. In Chile, Codelco operates seven mines. Located 80 km northeast of Santiago, the Andina mine, which includes both open-cast and underground extraction, produced about 248,000 mt of copper and approximately 7,200 mt of molybdenum per year.

Siemens is now responsible for servicing all the technical equipment at Andina. The contract covers both preventive and corrective maintenance of the following units: ore crushers, conveyor belts, grinders, flotation cells and the filter plant. Also included are the molybdenum plant, the mine winder and the piping system for the copper and molybdenum concentrate.
