Outotec to deliver 116 million euro copper plant for Codelco in Chile

Outotec has signed a contract with Codelco for the design and delivery of a copper concentrate roasting plant, gas cleaning system and sulfuric acid plant for Codelco's new Mina Ministro Hales mine close to Calama, Northern Chile. The contract price is approximately EUR 116 million.

Outotec's turn-key plant delivery includes basic and detail engineering, proprietary and process equipment, installation and start up services. Outotec and Codelco also signed a Memorandum of Understanding for two years' operation and maintenance of the new plant.

The new plant will treat annually up to 550,000 tonnes of copper concentrate and it will produce approximately 250,000 tonnes of sulfuric acid. The plant is scheduled to be commissioned in early 2012.

"Codelco, the world's largest copper producer, has been our business partner for decades. The company has high standards for operational safety and environmental requirements. This significant order demonstrates their confidence in the sustainability of our technologies and project execution competence", says Pertti Korhonen, President and CEO of Outotec.
