Copper is lighter than copper oxide. This is because copper oxide is a compound formed by the combination of copper and oxygen, which increases its overall mass compared to pure copper. Therefore, in terms of weight, copper is lighter than copper oxide. **

The chemical formula for copper oxide is CuO, for copper it is Cu, and for carbon dioxide it is CO2. Copper oxide is a compound formed by the combination of copper and oxygen, while copper is an element on its own. Carbon dioxide is a compound formed by the combination of carbon and oxygen. **

To produce copper from copper oxide, you can use a process called reduction. This involves heating the copper oxide with a reducing agent such as carbon (in the form of charcoal or coke) in a furnace. The carbon will react with the oxygen in the copper oxide, leaving behind the pure copper metal. This process is known as smelting and has been used for centuries to extract copper from its ores. Once the copper metal is obtained, it can be further purified and shaped into the desired form. **

Ötzi, the ancient iceman, likely extracted copper from copper ore using a technique called smelting. This process involves heating the copper ore in a furnace at high temperatures to separate the copper from the surrounding rock and other impurities. Ötzi may have used a combination of charcoal and blowpipes to create the necessary heat for smelting. Once the copper was extracted, it could be shaped and used for making tools and weapons. This demonstrates Ötzi's advanced knowledge of metallurgy and his ability to work with metal during the Copper Age. **
