Outotec to deliver a copper plant for Centenario Copper Chile

Outotec has agreed with Centenario Copper Chile S.C.M. for the delivery of a copper solvent extraction and electrowinning plant for the Franke project located in northern Chile. The contract price is approximately EUR 30 million.

Outotec's scope of supply covers engineering, technology and proprietary equipment supplies, construction, commissioning, and performance tests.

The Franke copper plant will incorporate Outotec's latest technologies, such as the solvent extraction plant including VSF (Vertical Smooth Flow) technology, the tank farm, and the electrowinning plant using Outotec's permanent cathode and stripping technologies. Outotec's delivery time for the plant, which is designed to produce 30,000 tonnes copper cathodes annually, is 15 months.

"Many mining companies are now exploring lower grade ore-bodies and are looking for technologies, which allow economical exploitation of these resources. With the average copper grade of 0.9%, the Franke deposit is a good example of this development. Outotec's technologies offer lower energy consumption and minimum operating costs, making it a viable solution for the customer", explains Tapani Järvinen, President and CEO of Outotec.
