Outotec to deliver a copper plant for Southern Peru Copper Corporation

Outotec has agreed with Southern Peru Copper Corporation (SPCC) for the delivery of a copper solvent extraction and electrowinning plant for SPCC's Tía María project in Arequipa region in Peru. The contract value is USD 150 million (over EUR 90 million), out of which USD 90 million is already included in Outotec's 2008 second quarter order backlog.

Outotec's scope of delivery covers basic and detail engineering, proprietary equipment and services for the construction supervision and commissioning.

SPCC's Tía María project includes the development of a new processing unit for the Tía María and La Tapada deposits. When completed in 2010, Tía María is expected to produce 120,000 tons of copper cathodes per year.

"This project is the largest solvent extraction and electrowinning project in Outotec's history and it further strengthens our position as a market leader in copper solvent extraction technologies," says Tapani Järvinen, CEO of Outotec.
