A metal such as copper was of great importance to humanity in the past. No wonder the whole era was called the Copper Age - then weapons, armor, tools, jewelry, dishes, and much more were made from this metal. But also Now the importance of copper cannot be overemphasized, since it is used in a wide variety of industries, from the space industry and mechanical engineering to the production of any electronics and many paints.
- About 80% of all copper products are recycled and reused, as the metal is too expensive to simply throw away after use.
- On the island of Cyprus, people mined and processed copper more than 4000 years ago.
- Among all metals in the world, copper ranks third in the world both in terms of production and consumption, yielding only aluminum and iron in these nominations.
- The purest copper is used for the production of wires and electrical cables. In this case, cleaning is required really as deep as possible, since any impurities sharply reduce the electrical conductivity.
- In copper deposits, this metal is quite often found in the form of pure nuggets, although sometimes it is also found with foreign impurities.
- Copper is a natural antibacterial agent and inhibits the spread of bacteria in water and air from systems made from copper. Likewise, brass door handles and handrails in public buildings can help minimize the risk of bacterial transmission since copper is part of the brass alloy.
- Among all metals, copper is second only to silver in terms of electrical conductivity. But silver is too expensive to use for most wires and other electronics.
- Due to its high thermal conductivity, copper has become an indispensable part of many cooling systems.
- Since copper is highly resistant to corrosion, it is usually from it that capsules are made for the disposal of toxic waste.
- Archaeologists have discovered copper pipes in ruins in Egypt, which were about 5,000 years old. Over the past millennia, these pipes, made by the ancient Egyptians, have not even lost their functionality.
- Copper itself is safe, however, the process of its extraction cannot be called such. The most toxic lake in the world, called Berkeley Peet and located in the United States, for example, was formed when water flooded a former copper quarry.
- Blood in mammals is red due to the presence of iron in it. And in some other animals, for example, in octopuses, the blood is blue, because instead of iron it contains copper
- In our body, however, this metal is also present. Most of it is found in our liver.
- Copper is essential for the normal functioning of the human body, and we get it from food. The average adult needs a little less than 1 milligram per day.
- If you hit one brass instrument against another, there will still be no sparks, no matter how hard you try. To strike a spark, iron is better.
- Copper is added to many jewelry alloys such as gold. This is necessary to increase the strength of the items and reduce the consumption of gold itself. Nickel is often added to the alloy.
- The Copper Age, which lasted more than 1000 years, ended when people learned to make bronze by alloying copper and tin nuggets
- It was copper, due to its softness and ease of processing, that became the first metal that began to be widely used by mankind.
- Many peoples attribute medicinal properties to copper. In particular, this metal is especially respected in Nepal.
- The average adult's body contains about 60-80 mg of copper.
