Is Copper Metal?

What is Copper?

Copper is a ductile and malleable metal with excellent electrical and thermal conductivity. Malleable and ductile describe metal's physical properties.

A metal that's malleable can be hammered, pressed and reshaped without cracking or breaking. It can also be rolled into thin sheets.

Ductile metals can be drawn or stretched into wire without breaking or losing strength. The wire is pliable, so can be bent or twisted without damage.

Copper alloys such as bronze and brass are often used to make musical instruments, including gongs and bells.

Although often described as a mineral, copper is a chemical element. On the periodic table, it's represented by the symbol Cu.

Copper is found in more than one hundred sixty minerals. Malachite is the earliest ore of copper. An ore is a rock that contains sufficient quantities of a metal to make it worth extracting.

Copper can be extracted from an ore with relative ease.

Much of the copper mined today comes from ores containing less than 1% copper. Chalcopyrite is the most common ore of copper.

Major copper-producing countries include Chile, the Democratic Republic of Congo, Peru, China, Indonesia, the United States, Russia, Australia, Zambia and Mexico.

Copper was the first metal used. Beads found in Iraq date back more than 10,000 years. Over time, it was discovered copper could be worked which made it more suitable than stone for tools and weapons.

The Bronze Age began with the development of bronze around 3000 BC. Bronze is an alloy of copper and tin.

An alloy is a mixture of two or more chemical elements, at least one of which is a metal. Alloys are produced because pure metal is often too soft to be suitable for its purpose.

The combination of copper and tin produced a metal far stronger than pure copper. Copper was still used extensively, but the discovery of bronze marked a significant technological advancement due to its improved strength and durability.

In ancient Egypt, copper was used for tools, cookware, mirrors, razors, and even makeup. Blue and green cosmetics were produced by grinding malachite or azurite and mixing them with oil or fat to produce a fine paste.

During the Industrial Revolution, copper became even more important because of its ability to conduct electricity.

Today, copper is still widely used for electrical wiring, plumbing, roofing and construction. Although copper tarnishes, it's highly resistant to corrosion.

Throughout history, copper has been used to produce cutlery, cookware, jewellery, decorative objects, and coins.

Copper is used for cookware because it conducts and distributes heat exceptionally well. Even distribution is important because it prevents hotspots that can burn food.

Copper also has antimicrobial properties. An antimicrobial is a substance that kills microorganisms, such as bacteria or mould, stopping them from growing and causing disease.

Tests have shown that a solid copper surface can kill 99.9% of certain bacteria within two hours of contact. two industrial lorries in an open mining area

Is Copper Renewable?

Copper is a non-renewable resource because it's mined from finite deposits in the Earth’s crust. However, it's highly recyclable and can be recovered from waste products such as electronics and scrap metal.

Recycling copper reduces the need for new mining and generally uses less energy than producing copper from ore.

Is Copper Valuable?

Copper is a valuable but highly volatile commodity. Its price is influenced by global demand, industrial activity, mining output and available stockpiles.

As countries move towards cleaner energy, demand for copper is expected to increase. Some forecasts warn that supplies may struggle to keep pace over the coming years.
