• Recycling a tonne of copper uses 20% of the energy that would be used to mine and extract the same copper. • The copper recycling process has much in common as that to extract it, but requires fewer steps. High-purity copper is melted in a furnace and then reduced; Low-purity copper is refined through electroplating in sulfuric acid.
