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. **
