Outotec has signed a contract with Codelco for the design and delivery of a copper concentrate roasting plant, gas cleaning system and sulphuric acid plant for Codelco’s new Mina Ministro Hales mine close to Calama in northern Chile. The contract price is approximately €116 million ($158 million).

The 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 up to 550,000 metric tons per year (mt/y) of copper concentrate and it will produce approximately 250,000 mt of sulphuric acid. The plant is scheduled to be commissioned in early 2012.
