Metals
What is a metal? A metal is a substance, which have distinctive qualities of particular type. Metals usually are shiny, hard opaque and good conductors. In ancient Latin and Greek it has been written that Theophrastus and Pliny The Elder were the ones who crated metals by characterising the chemical and physical properties. Theophrastus is a Greek philosopher who lived during 371-287 B.C. Pliny the Elder during AD 23-79 was a Roman author, naturalist and naturalist philosopher. During this period there were 86 known metals.The first discovery of metals were Gold (Au) and Copper (Cu). Then four other metals were discovered. They were called Arsenic (As), Antimony( Sb),Bismuth (Bi) and Zinc (Zn).While the metals where discovered naturalists …show more content…
Iron is the next commonest metal on the earth. It may be found in the sun as well as in other, different types of stars. Iron is a one of the main elements used for meteorite classification. Meteorite classification is a group of meteorites of common origin, for example a planet moon asteroid or basically the other object in solar system. A German chemist called Gunter Wanchtershauser discovered reactions of Iron sulphide(FeS) with a help of another philosopher called Karl R.Poppe. Iron has an important place in Biology because it binds with molecular oxygen in myoglobin and hemoglobin. During the ancient time, iron was found and collected from meteors and that type of irons were easily distinguished from the normal iron found on Earth because it contained 6-8% nickel. There is no proof found that man made iron in 2500 B.C. Iron was used as beads and ornament however. If iron was heated to the temperatures below 700 to 800 degree it was not possible to forge things because that requires a temperature of about 1100 degrees Celsius. The first shape of iron known to man was wrought iron. Iron was more expensive than gold during the iron …show more content…
Rare metals is the set 17 in the periodic table including Scandium( Sc) and Yttrium (Y). Scandium and Yttrium are included because they both have similar ore. China has the biggest mines for the Rare metals for Technology. Rare metals are important elements for the technology development of today. Rare metals can be found in cell phones, etc.
The metal doesn’t get manufactured in a factory because the ore and other kinds of minerals are used to form the metal. When they have got the ore and minerals they melt it and the melt is formed into clean metal. To get the ore they excavate the mountains and soil and drill tunnels. When they have got the ore they crush it into small pieces, which are up to 10 cm each, and then send it to the processing plants. They put the ore in water to move away the dirt. The ore is then sent through a magnetic separator, the magnetic substances (the metal) splits up into two piles, one for the small pieces and one for the bigger pieces.The stones gets crushed into really small pieces and the bigger pieces of ore gets crushed to small pieces like the other group of ore. After that, they mix all the pieces together and then they melt everything. The metal is poured in to molds where it
