Copper is a chemical element with the symbol Cu (from Latin: cuprum) and atomic number 29. It is a soft, malleable, and ductile metal with a reddish-orange color. It is a good conductor of electricity and is widely used in construction, electrical wiring, and coins. At CK-Mining, we operate in mines around the world, where we offer high-quality copper specimens for collectors, as well as large quantities of copper for industrial uses.
Copper is a dense metal, with a specific gravity of around 8.9. It is relatively soft, with a Mohs hardness of around 2.5-3. It is typically reddish-orange in color, but can also be found in shades of blue and green. It has a metallic luster and is often opaque.
Copper is found in many locations around the world, with notable deposits in Chile, Peru, China, and the United States. It is usually found in ore minerals such as chalcopyrite, bornite, and chalcocite. It can be mined using open-pit or underground mining methods.
