The selective leaching of copper from a goldcopper

gold leaching either using the same process at elevated temperature (4060 °C), as patented by the authors, or using a cyanidation process. Copper selective leaching will reduce the gold losses due to a cementation mechanism of gold in the presence of metallic copper as all of the metallic copper will dissolve in the preleaching stage.
