Copper Cu Atomic Number:29 Atomic Mass: 63.55 State(room temperature):solid Boiling point:2562 °C Melting point:1084.62°C Gerneral Information o.oo5%of Earth crust is made of Copper History of Copper Bohr-Rutherford Diagram of Copper No one actually knows or found out who discovered copper, because it was discovered back between 5,000 B.C. to 1,200B.C, which is a very long time ago. Also, it was found that it has been used for 11,000 years. Around the whole world, there are a lot historic sites that were discovered reveal people use copper for different purposes. Romans, Jordan, Egypt and Israel have copper melting locations back to 4500B.C. Copper was also widely used in Southeast Asia and Turkey between 4000 B.C. to 5000B.C. As well in Cyprus, Agia Varvara-Almyras, where there were copper smelting site and may use to produce the alloys of copper. Raw Material Copper is found from its own ores, which is copper ores. Chalcopyrite and similar sulphide are commonest ores of copper. It is mined or extracted from large open-pit mines in porphyry copper, where it contains 0.4% to 1.0% copper. Ores have low percentage of copper (average concentration is 0.6%), which means it needed to be concentrate to separate copper from other elements that contain in the ores. First the ores needed to be reduced in size, which is called comminution. Then copper is extracted from the ore by hydrometallurgical liberation for oxides and froth flotation for sulphides. After the partially refined copper goes to smelting, the resulted copper has to be additional refined in several processes. Common use/application of Copper Copper is widely used for different categories, for industry, services, electrons and architecture. Here are some most common uses of copper:
• Copper wire
• Copper pipes(i.e. piping for water supplies)
• Refrigeration
• Air conditioning
• Coins
• Roofing material for buildings
• Sculptures Properties of Copper Physical properties of copper:
• Shiny, solid, copper red, very malleable, ductile, opaque, conducts electricity, and high density.
Chemical properties of copper:
• Natural copper contains Ag, As, Sb, Bi or Hg
Social Impact • Advantage of copper:
Copper is one of the best conductors of electricity, so it’s widely used for wires, as you can always find copper wires at your household. Also, like it’s been listed in the common use of copper, it’s been commonly used in different categories, due to its physical properties-malleable, ductile and conducts electricity, i.e. malleable so it can bend into copper pipes, which could be used for water supplies. The third advantage could be the benefit to human body, as an adult intake 1.5~3.0mg per day, so it is necessary for our daily life.
• Disadvantage of copper:
Although copper has many advantages, it still has cons. The biggest impact to society, it’s the pollution that made out of the smelting of copper from its ores. It would cause pollution from SO2 to the neighbouring area. In addition, the mining for the copper ores are huge impact to the environment, as the ores were dug out from the mountains and nothing was filled in anymore, which could cause soil erosion to the near village, or even landslides to the near village. Last, the disadvantage is pure copper is really expensive to buy, as the ores are going less every year.
COOL FACT! Copper has a LOT of uses due to its properties and it’s one of the most familiar metals in our daily life. But there also are many cool facts about copper, too. Here is a list of cool fact of copper. • During the Roman Empire, copper was mined on Cyprus, so its original name is “metal of Cyprus”, but later was shorten to “Cuprum”, the chemical symbol Cu is from “Cuprum”. • Copper’s toxicity makes it effective for preventing bacterial growth, which is why doorknobs in hospitals are made of copper. • Canadian penny is no longer made of copper, since 2000, pennies are made of only 4.5%copper and others are steel, the copper just to give the coins their copper color. • The average of copper that is containing at the household is 400 pounds for copper wire, pipes. • The car you drive contains 50 pounds of COPPER! • Copper is a better conductor of heat and electricity than other metals, except silver. Without copper, there might ever been an electric light or space flight. Work Cited Stwertka, Albert. A Guide to the Elements. New York: Oxford University Press, 1998. 96-97. Print.
