The process uses low temperature pressure oxidation to directly leach copper from the ore followed by SX/ EW of copper from the resulting leach solution. The plant operation achieved an annualized copper production of 50,000 tonnes Cu as LME grade cathode in 2002. The choice of pressure oxidation for this application was driven by necessity.

Over the past 40 years, the copper mining industry has undergone a dramatic shift toward hydrometallurgical extraction of copper at the mine site. This has increased the importance of recovering high-purity copper by electrowinning. High-purity cathode production was achieved by implementing numerous technologies including superior …
World Copper Ltd. updates its NI 43-101 technical report for the Escalones project in Chile, enhancing copper mining prospects. Details on
The heap leaching process has been widely used for recovering different metals since its first application at the end of the 1960s. In Chile, copper production via heap leaching has accounted for between 30 and 40% of annual copper production over the past 10 years. This level of production has been achieved through and supported by …
copper oxides have been in common use for some time. Prior to the development of the Sherritt-Gordon process for nickel and cobalt in which copper is recovered as high grade copper sulfide, copper sulfides were economically recovered in a hydrometallurgical process only during the leaching of waste dumps. . Need for Hydrometallurgical Processes

In 2012 it accounted for five per cent of global copper production and around 15 per cent of Chilean copper production. The mining operation includes an oxide ore heap leach plant processing approximately 20 mt/y of ore. The ndida Mine is the largest copper mine in the world and is located in the Atacama Desert in Chile.
Importance of Laboratory Testing to Leaching Plant Design. Batch tests and continuous pilot plant tests can be conducted of the entire leach circuit to accurately determine the results of a full scale commercial operation. Process efficiency is often the controlling factor of plant profits.

The dissolved copper is then concentrated and purified in the leach solutions at a solvent extraction plant. Finally, an electrowinning plant produces high-grade, high-quality cathode copper. From the beginning, Zaldívar's electrowinning plant had the capacity to produce 125,000 tonnes of cathode copper annually.
