Copper is a chemical element with the symbol Cu and atomic number 29. It is a reddish-orange metal known for its excellent electrical and thermal conductivity, ductility, and resistance to corrosion. As one of the most widely used metals in human history, copper has been valued since ancient times for its malleability and antimicrobial properties.
Geologically, copper occurs naturally in various forms, including pure nuggets and as a component in ores such as chalcopyrite and malachite. It is primarily extracted through mining and refining processes, with major deposits found in countries like Chile, Peru, and the Democratic Republic of the Congo.
In terms of applications, copper plays a crucial role in electrical wiring, plumbing, and electronics due to its superior conductivity. It is also essential in alloys like bronze (copper and tin) and brass (copper and zinc), which are used in coins, musical instruments, and machinery. Additionally, copper’s antimicrobial qualities make it ideal for medical devices, water purification, and even architecture.
Economically, copper is a key commodity on global markets, influencing industries from construction to renewable energy, such as in solar panels and electric vehicles. Its price fluctuates based on supply, demand, and geopolitical factors, but it remains vital for modern infrastructure and sustainable technologies.
