Copper ore types: Oxides. The copper sulfate solution (called the pregnant leach solution) is then stripped of copper via a solvent extraction and electrowinning (SXEW) process. Alternatively, the copper can be precipitated out of the pregnant leach solution through a process called cementation, whereby the copper is contacted with scrap iron.
