open-pit mining

Answer 1

The primary mining method used for copper is open-pit mining. This method is commonly employed because copper ores are typically found close to the surface and can be extracted efficiently in large quantities. Surface mining methods, including open-pit mining, are preferred for the extraction of copper over other methods like placer or in situ mining.
