Data for this chart is from the United States Geological Survey Mineral Commodity Summary for 2020. As an example: copper used in building construction could have been used for wiring, plumbing, weatherproofing and many other individual types of use. Uses of Copper: This graph shows how copper was used in the United States during 2019 by industry sector. These discoveries suggest a long-distance trade connection between Georgia and the Great Lakes region, a greater distance than was ever known before. The copper contained trace elements that linked it to geological deposits in the Great Lakes region. The burial was a cremation dated to roughly 3500 years ago. In the United States, a piece of what is believed to be a copper bracelet was found in a Native American burial on the coastal plain of Georgia in 2017. The discovery that copper alloyed with tin produces bronze marked the beginning of the Bronze Age at about 3000 B.C.
Copper was first used in coins and ornaments starting about 8000 B.C., and at about 5500 B.C., copper tools helped civilization emerge from the Stone Age.

It is also more costly to replace existing fixtures and equipment than designing with copper from the start. Another is cost - copper can be more expensive than other options. One reason is that many medical professionals are unaware of the benefits of copper. The benefit of copper on high-touch surfaces has been known for years, but hospitals have been slow to implement. Some pathogens were killed in minutes on dry copper surfaces. Frequently touched surfaces tested in studies include bedside rails, tray tables, intravenous poles, and chair armrests
In hospitals, the use of copper and copper alloys on frequently touched surfaces can reduce the number of patients who acquire infections during a hospital stay. Why? Copper has antimicrobial properties that are effective against a wide variety of disease-causing organisms. COVID-19: Research has shown that the novel coronavirus, responsible for the COVID-19 pandemic, can survive for days on glass, plastic, and stainless steel surfaces, but dies within hours on a copper surface.
