Copper is a plentiful natural resource on Earth. At the current rate of extraction there is enough copper in the top kilometer of the Earths crust to meet demand for 5 million years.
Nearly 80% of all the copper we have ever produced is still in use today due to the fact that copper is 100% recyclable and retains 95% of its original value.
Numerous important copper alloys have been produced over human history. Brass is a mixture of copper and zinc, bronze is an alloy of copper and tin. While cupronickel is a combination of copper and nickel.
Small amounts of copper can be found in a natural state while the metal is also found in minerals such as cuprite, malachite, azurite, chalcopyrite and bornite.
