• Copper | The Canadian Encyclopedia

     · Copper. Copper (Cu) is a malleable, ductile, reddish metal that melts at 1083°C. Copper has both a high electric and thermal conductivity. Only silver is a better thermal and electrical conductor. In general, copper has good resistance to corrosion, although when exposed to the environment, the surface of the metal oxidizes to form a light green patina or a black oxide coating.

  • Smelting

    Smelting is a process of applying heat to ore in order to extract a base metal. It is a form of extractive is used to extract many metals from their ores, including silver, iron, copper, and other base uses heat and a chemical reducing agent to decompose the ore, driving off other elements as gases or slag and leaving the metal base behind.
