Copper – a unique metal
Copper is a metal that can be recycled as often as desired without a loss of quality. Recycling not only saves the energy that would be needed for mining and preparing the ores melting down recycling material also requires less energy than metal production from copper concentrates. Our modern life wouldn''t be possible without copper.
