Minerals
Stores subsoil lot of different minerals that are essential in the mineral industry and spread of these metals in the form of metals mixed with other substances like
sulfur or chlorine or not ** Jane etc ... as races may be a net.
We have found that the so-called rock groups is the name of metal materials that are earth's crust.
With that there are many rocks consist of one metal material such as those that exist in abundance in the alpine region and that gives us white marble, it is made up of metal and one is calcite. The group Dolomite mountains in northern Italy is made up of rocks and other vehicle is of metal Aldoolomt. These rocks, known as ((Statistics rocks)).
The metallurgy is a science that deals with the natural minerals that are found within the earth's crust condition. This flag is also looking at the properties of metals and works with them to detect and analyze samples careful analysis to detect physical and chemical composition, characteristics and other ...
It consists of metals chemical element and one is a famous tab known as sections ((Mendeleev table)). That it is rare to find any of them in isolation or in the case of purity sincere. It is often found various other elements of the pillars of the same, even if we found pure or by a very small proportion of impurities, we call it the name ((pure element)).
• Gold: 2.5 degree of hardness, specific density of 19.6 g / cm 3, a yellow and metallic luster. There is either a gold dust and either in the form of particles or granules. And what's more gold is used in jewelry industry, if the caliber of 24-carat pure gold was and if it was 18 carats contains 75% pure gold.
Gold has impressed people since ancient times they sought him and battled him. You can pull gold in the form of thin sheets per thickness of which does not exceed 12000/1 mm. That acquires hardness If mixing copper. Within the soil it takes the form of veins or mixed with sand has led to the search for new geographical discoveries and the densely populated cities in places may not be habitable. It is also used as a cover for criticism paper in most countries of the world and in jewelry, coins and paint pots industry.

• Silver: the degree of hardness 2.5 - 3, qualitative density of 10.5 g / cm 3 for a white metallic luster. They are found in the form of tree blocks or in the form of intertwined filaments and the largest mines are in pain Iike ** In Canada, Peru, used almost as gold.
• Copper: The degree of hardness 3, qualitative density 8.9 g / cm 3, to the color red, metallic luster. It is a relatively rare metal and there in the form of antiseptic beautiful complex crystals. It was discovered by the Iron: The countries of the eastern Mediterranean known copper and used it since about 3600 BC.
Lin and copper in its natural state, but is gaining a bit of hardness if mixing tin, so that gives a bronze tin to be 8% of the total weight. And also it blends with nickel, zinc or with silicon and manganese with gold or gives other forms of metals are used in various industries.
Copper is found in nature and a net in the form of metals are: copper sulfur ScU, or hand ** Copper CuO, polycarbonate and copper co3cu. The industry is going through in three stages: the first and second concludes in which impurities are separated from the rest of minerals and third net to make it pure. And the process of conducting these purified by electrolysis solution in industrial centers where electricity is available. Copper is also used in machinery and flexes the radio industry and in some household appliances and cars.
Copper production is distributed in the following countries: the United States, Russia, Canada, Althley, Peru, pain ** Iike ... etc. It is estimated copper reserves in the world's 130 million tons, of which 70 million tons in the Americas alone. That's what made it for a period of controlling the trade in copper along with Japan, but aluminum and other metal alloys that have managed solutions replace copper eased crowding out of this control.
• Platinum: 4.5 degree of hardness, density quality 21 g / cm 3, which is white gray, metallic luster. It is there in the form of round granules, especially in the Urals in Russia, Canada and Colombia. Platinum is used in jewelery and precious Alwatq vessels and laboratories if the degree of melting in 1750 D.m.
That must be available in iron ore, in order to be usable the following conditions: to be rich in iron which contain 60% of the iron, to be pure of harmful impurities such as phosphorus and beneficial Kalkrom, and to be finally plentiful.
Rail industry is characterized by extremely important and profoundly affect the economic situation and therefore the political situation. The spread of iron in the earth's crust at different rates ranging between 5 and 70%. The most important rock that is extracted from it: Almagnati, (which Ajodha) and hematite and limonite and Alsedric.
And the intervention of some metals in the iron industry standing, hardness and resistance are: manganese. The most important countries which are produced by Russia, India, South Africa and Brazil. And also it enters Almrom important producing countries are: Russia, South Africa, Turkey, Cuba, Rhodesia. Altangostin The most important producing countries are Malaysia, China, the United States.
Finally we point out that 85% of North American production of iron is in the Lakes region and that Peru and Russia produce minerals mixed with iron increases the hardness Hee vanadium.
• Aluminium: a modern metal discovery, since it only discovered in the late nineteenth century and after the remarkable progress in the science of chemistry g extract mixed with Bala ** Jane in the form of metals called ** At Albu, relative to the French city of Bauxe, where it was for the first time , the world's chemical and Keller Wokler.
And metals Albu ** At containing ratio ranging between 20 and 25% of the raw aluminum. After we get rid of impurities on the hands or ** pure aluminum (alumina) and then separates the initial Jane ** Secretary-by power supply we get pure aluminum.
Features that aluminum metal lighter weight and transmission of electrical current and, thanks to its color White harmful to acquire resistance to blue if mixing copper and magnesium is used in the manufacture of kitchen utensils in the automotive, wire and motor industry and aircraft industry.
Aluminum production is distributed in the following countries: France, Hungary, Italy, ... etc. That Jamaica occupies first place in the production.
radioactive minerals: uranium
Uranium ore were not to know before World War II and then take him exploration is increasing in the world. That metal is present in rocks dating back to the era of pre-Cambrian rocks in the first phase. A fierce blast is used in nuclear power, which in turn is going ships and submarines and generate electricity making. The world's uranium is used for peaceful purposes in medicine shops military purposes.
There are more likely radioactive metals are Ataiwriom and lithium, hydrogen, plutonium and fission are all Qaalh.
Not suitable for the exploitation of uranium ore that were not contained on the ratio of not less than 2 per thousand of any metal 2 kg of metal in a thousand kilos of metals.
nonferrous metal: the most important.
• Diamond: chemical composition of carbon is met, the degree of hardness 10, awareness density 3.5 g / cm 3. Raw diamond is not sheen polished diamonds show curvatures in the face. Then it is rare.
