Sources for ore rocks often exist in areas of stream flow in the form of placer deposits. In South America, preColumbian civilizations found platinum intermixed with gold in river deposits. The largest platinum deposits reside in Russia, South Africa and Zimbabwe, with smaller deposits in Canada and the United States.
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.
