A Brief History of Copper Discovery Copper is one of the metals that have been known since ancient times. It is generally believed that the first metal known to mankind is gold, followed by copper. Copper is very rich in natural reserves and easy to process. Copper is the first metal used by humans for production. At first, people used only natural elemental copper, which was found in nature. When it was cut down with a stone axe, it could be hammered into various utensils. With the development of production, only the production tools made of natural copper are not enough. The development of production has prompted people to find a way to obtain copper from copper mines. Copper-containing minerals are more common, mostly with bright and striking colors, such as: golden chalcopyrite CuFeS 2 , bright green malachite CuCO 3 Cu(OH) 2 , dark blue azurite 2CuCO 3 Cu (OH) 2, etc., these ores are calcined in the air to form copper oxide CuO, and then reduced with carbon to obtain metallic copper. The utensils made of pure copper are too soft and flexible. It has been found that tin is incorporated into copper and can be made into a copper-tin alloy - bronze. Bronze is harder than pure copper, which has greatly improved the labor tools and weapons made by people. Humanity entered the Bronze Age and ended the Neolithic Age in human history.
According to Western legend, the Cyprus island of Cyprus in the ancient Mediterranean was the place where copper was produced, thus obtaining the Latin name Cuprum and its chemical symbol Cu. The English name of copper is Copper.
