The secret of gold in its

 

Gold remained high value over the years, due to its rarity. But gold owed much of the physical and aesthetic properties, flexibility, resistance to chemicals, as well as its density. It is a beautiful yellow color, striking metallic luster, and is easily filled and formed a thin foil of latsada, for its ability to resist rust and other chemical changes caused by air.
You must mix gold with another metal to make solid body as jewelry pieces, for example. This mixture is called slug. And gold alloys measured by carat, Carat is equal to one of the twenty-four part. Thus, the 24-carat gold is pure gold. 18 k gold and consists of 18 part of gold and 6 parts of other metal.

How to be a gold

 

Scientists believe that gold was the deposition of gases and liquids from underground through the cracks of the Earth’s crust in the form of veins or ranges or crushed this grain and banding and movement across the river tributaries during floods, torrents to be so-called sediment concentrations were found.
All sea water containing gold can produce of sea water 72 mg of gold per metric ton. Scientists looking for ways for profitable investing.
A rare image of pure gold, but is often accompanied by silver in an alloy called Electrum, natural and is usually combined with quartz or  the kelsit, or lead, tellurium, zinc or brass, often extracted as a by-product of these minerals. For example, 40% of the gold mined in the United States, is extracted from the sites might be named a gold mine.

The gold more beautiful and clean condition value than most other metals. Features generally yellow in color but may be black or purple when it is in the form of granules. In addition, gold is soft and flexible and its way better than most metals. The piece of gold weighing 20 grams can be addressed to be a 6 square meters plate. Because of these characteristics it is mixed with some minerals to impart strength and rigidity required. Gold is also an excellent conductor of heat and electricity. Here are some physical properties of gold metal.

Chemical properties

 

Gold belongs to the Group of transitional elements of atomic number 79 in Group 11 and COP 6 of the periodic table. Gold has a number of chemical properties do not interact with oxygen, and is not affected by weather or acids such as nitric, hydrochloric, sulphuric acid and other chemical compounds. Nor is it easily reacts with halogens such as chlorine and bromine. But has the ability to dissolve gold from the Royal water consists of blending part of nitric acid with three parts of hydrochloric acid. Addition of oxidizing materials such as halogen acid hydrogen chloride, hydrogen weibiroxid acid or chrome to dissolve gold.

 

Gold is one of the rarest elements in the Earth’s crust 10 quality 0.005 ppm. For example to get ounces of gold being extracted about 30 tons of rock. And believed that its presence in the Pacific, where some believe that nearly 70 million tons of it dissolved in the oceans and others believe that there are 10 million tonnes below the oceans. So far, there is no way to extract the gold.
