The development of TL-SX-EW copper cathode production in Chile since 1990 is shown in Fig. 9.1. Rapid expansion occurred during 1995–2010, and production of 2088 kt of SX-EW copper cathodes was obtained in 2010. During that period, bioleaching also attracted interest and reached a significant level of maturity.
BHP Billiton's Spence copper cathode project is located 1,700m above sea level in the Atacama Desert in northern Chile, close to the mining town of Sierra Gorda, 50km south west of Calama and 150km north east of Antofagasta. Feasibility studies were completed in 2002 with mine approval granted in 2004. The mine reached design …

Problems created by CN‐soluble copper in leach solution Copper contamination of gold cyanidation circuits causes a number of problems in gold processing (Sceresini, 1999). Copper oxide minerals (i.e. azurite, malachite, cuprite, tenorite) have fast leaching rates in cyanide. Secondary copper sulphide minerals such as chalcocite and covellite ...
Copper was extracted on asphalt-lined leach pads and recovered in the first solvent extraction and electrowinning (SX/EW) plant in Latin America. Production capacity was 33,000 metric tonnes per year (mtpy) of high purity copper cathodes. At the time, the use of solvent extraction followed by electrowinning for low grade, impure …
Minera Escondida, located in the Antofagasta Region of northern Chile, is the world's largest producer of copper as concentrate and SX-EW cathode. Projects to increase mill and flotation capacity began soon after start-up in 1990 to off-set decreasing copper grade. Subsequent projects had the objective to increase copper production …

In addition, Phelps Dodge anticipates a 10% cost-of-production savings, between $0.07 and 0.09/pound of copper, as a result of the new processing regime. While Morenci will not be the world's first mine-for-leach operation, at 75,000 t/d (tons per day), it will be the largest by far. Similar operations that preceded Phelps Dodge's entry include ...
30% Copper (predominantly Chalcopyrite, Bornite and lesser amounts of Chalcocite) 19% Total Sulphur. 14% Iron. Being originally designed as whole ore leach tanks, their sizing was excessive compared to the planned feed rate and selected equipment. Commissioning took approx. 6 weeks and we managed to achieve a copper leach recovery of >99%.
The flotation tailing then is thickened to about 40 percent solids and sent to the slime leach plant for extraction of copper from the acid-soluble oxidized copper minerals. The process has been described by Power. The slime plant consists of three 20-foot-diameter redwood leach tanks.
