Outotec to deliver a copper plant for Minera Lumina Copper in Chile

Outotec has agreed with Minera Lumina Copper S.A. on the delivery of a copper solvent extraction and electrowinning plant for the Caserones project, located in high mountains in northern Chile. The contract value is approximately EUR 65 million.

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

The Caserones copper plant will incorporate latest Outotec® technologies, such as solvent extraction with Vertical Smooth Flow (VSF) technology and tank farm, as well as electrowinning using Outotec® permanent cathode, acid mist capture and stripping technologies. Outotec´s delivery time for the plant, which is designed to produce 30,000 tonnes of copper cathodes annually, will be 30 months.

"Many mining companies are now exploring lower grade ore-bodies and are looking for technologies, which allow economical utilization of those resources. With an average copper grade of 0.34%, the Caserones deposit is a good example of this development. Outotec® sustainable technologies offer low energy consumption and minimum operating costs, making it a viable solution for the customer ", explains Pertti Korhonen, President and CEO of Outotec.
