Abstract
Copper is one of the first metals utilized by humankind about 11,500 years ago. But copper is not plentiful metallic element in the earth's crust. Copper has a high thermal and electric conductivity and is relatively corrosion resistant. In principle copper is virtually 100 % recyclable as an element without loss of quality. The recycling of copper scrap reduces the energy consumption and environmental burden, comparing to the primary metal production. Currently, approximately 30% of the global copper supply provides by recycling. Copper scrap is smelted in primary and secondary smelter. Type of furnace and process steps depend on the quality and grade of scrap. Depending on copper content of the secondary raw material, refining is required, which is usually done through electrorefining. This work provides an overview of the primary copper production and recycling process.
