Copper extraction Wikipedia

The copper sulfate solution (the pregnant leach solution) is then stripped of copper via a solvent extraction and electrowinning plant, with the barred (denuded) sulfuric acid recycled back on to the heaps. Alternatively, the copper can be precipitated out of the pregnant solution by contacting it with scrap iron; a process called cementation

Heap leaching Wikipedia

The mined ore is usually crushed into small chunks and heaped on an impermeable stone or clay lined leach pad where it can be irrigated with a leach solution to dissolve the valuable metals. While sprinklers are occasionally used for irrigation, more often operations use drip irrigation to minimize evaporation, provide more uniform distribution of the leach solution, and avoid damaging the exposed mineral. The solution then percolates through the heap and leaches both the target and other minerals. This process

Copper Mining and Processing: Processing of Copper Ores

Copper processing is a complicated process that begins with mining of the ore (less than 1% copper) and ends with sheets of 99.99% pure copper called cathodes, which will ultimately be made into products for everyday use.The most common types of ore, copper oxide and copper sulfide, undergo two different processes, hydrometallurgy and pyrometallurgy, respectively, due to the different

Copper Mining and Processing: Resources and Glossary

For copper oxide ore, heap leaching is the first stage in the process of hydrometallurgy, in which a stone solution is applied to a heap of crushed ore, through which it percolates, dissolving the copper. The resulting pregnant leach solution is collected for further refining via solvent extraction

Innovations in Copper: Mining & Extraction: Producing

Prior to the development of the solvent extraction-electrowinning (SX/EW) process in 1959 (see Copper the Green Metal), the only way to recover copper from an acid solution was by a process called cementation. In this process, copper was in effect "traded" for iron by contacting the copper-bearing solution with scrap iron. Impure metallic copper was precipitated on the iron surface while an

Valves for copper leaching, solvent extraction and

The liquid percolates through the stockpile and dissolves copper minerals, producing an approx. 60% copper concentration called pregnant leach solution (PLS). The PLS then flows to a collection reservoir and to the solvent extraction plant; the copper is then transferred from the mildly acid aqueous leach solution to an organic solution.
