Tenova TAKRAF and Tenova Bateman Technologies will design and deliver a copper ore handling/processing system and a solvent extraction-electrowinning (SX-EW) plant that will produce 80,000 metric tons per year (mt/y) of fine copper cathodes for Minera Antucoya, part of Antofagasta plc. The new plant, with a life time of approximately 20 years, will be located in the Antofagasta region, approximately 45 km east of the Group’s Michilla mine, in Chile.
These contracts will include engineering, supply of proprietary equipment, construction, training, commissioning and start-up supervision. Tenova TAKRAF will provide an agglomeration plant, an on-off leach pad measuring 3,000 m by 800 m, and a waste handling system and Tenova Bateman Technologies will supply the SX plant based on Bateman Settler technology. This is a proprietary reverse-flow mixer-settler (RFMS) technology that was developed and patented by Bateman, and is used in various plants in Chile, including Codelco’s Gaby plant and Vale’s Tres Valles plant.
