Copper

 Copper is a reddish-gold colored metal that is ductile, malleable, and an effective conductor of heat and electricity. Copper was the first metal to be worked with by humans and is among the most widely used metals today.Copper combines well with other metals to form widely used alloys such as brass and bronze. Copper is considered a base metal, as it oxidizes relatively easily. It has the symbol Cu and the atomic number of 29 on the periodic table. The name is derived from the Latin aes Cyprium, meaning ore from Cyprus. The discovery that copper could be alloyed with tin to form bronze gave rise to the Bronze Age.

Copper was used to make coins along with silver and gold. It is the most common of the three metals and so is the least valued. All U.S. coins are now copper alloys, and gun metals also contain copper. Most copper is used in electrical equipment such as wiring and motors. It also has uses in construction, for example in plumbing, and industrial machinery such as heat exchangers.

1Copper is a chemical element; it has symbol Cu (from Latin cuprum) and atomic number 29. It is a soft, malleable, and ductile metal with very high thermal and electrical conductivity. A freshly exposed surface of pure copper has a pinkish-orange color. Copper is used as a conductor of heat and electricity, as a building material, and as a constituent of various metal alloys, such as sterling silver used in jewelry, cupronickel used to make marine hardware and coins, and constantan used in strain gauges and thermocouples for temperature measurement.Copper is a mineral. it is not a plant or a animal. Copper is a metallic metal. It can never be broken down into differnet substances by normal chemical means. Copper was one of the first metals known to humans.

People liked it because in it’s native condition, it could easily be beaten into weapons or tools. Copper has been one of the most useful metals for over

5000 years. Copper was probably used around 8000 B.C by people living along the

Tigris and Euphrates rivers. In 6000 B.C, Egyptians learned how to hammer copper into things they wanted. Around 3500 B.C, People first learned how to melt copper with tin to make bronze. So the period between 3000 B.C …show more content…

Lamps are also attached to these helmets in case some of the lighting in the mine goes out leaving a miner stranded in the dark. One of the biggest problems with mining is that in some places dangerous gas’s may exist, like Carbon Monoxide. In the past we had very cruel and inhuman ways to detect harmful gases. One of these ways was the use of canaries. Miners would let them fly into a part of the mine where a poison gas was suspected. If there was a harmful gas, the bird would fall over dead at the first scent of the gas. Today, we have better ways to detect gases without having animals die. We now have detection machines in all parts of mines. Mines also have top of the line fire alarms and water systems. If a flammable gas ignites, like sulfur, the fire may not die for years, which results in closing the mine. Another problem miners complain about are the rats. Mines will often have mine cats that hunt out the rats. These cats are well fed and petted by most of the miners.

               Most copper is found in seven ores. That means it’s mixed in with other metals like lead, zinc, gold, cobalt, bismuth, platinum, and nickel. These ores will usually have only about 4% pure copper in them though.

Sometimes miners may only find 2%. The things that make copper such a popular metal are malleability which is how easily it bends. Coppe
