      HistoryProductionDistributionCopper FactsPhysical Properties of CopperNeolithic humans about 10,000 years ago first used native copper as a substitute for stone. The Egyptians and the Sumerians invented metallurgy, first reducing ores with fire and charcoal about 4000 BC. Copper was intentionally alloyed with tin as bronze about 3500 BC, and this harder metal was so universal in early history that one period is known as the Bronze Age.Copper is easily worked and is remarkably ductile.

    • Copper Mineral Uses and Properties Geology

      Native copper is an element and a mineral. It is found in the oxidized zones of copper deposits; in hydrothermal veins; in the cavities of basalt that have been in contact with hydrothermal solutions; and as pore fillings and replacements in conglomerates that have been in contact with hydrothermal solutions.
