Blue, red agate, emeralds, diamonds and jadeite, gold, the most important gems that are extracted and sold and exchanged. A lot of precious metals are considered a rich source of the human person, and sometimes a measure of the level of living and riches, it is the rarest kinds of precious stones in the world possesses a must and it is one of the richest men in the world. In our article we will talk about one of the most important of these metals, namely the (gold).

What is the gold placers
What is the gold placers is gold placers is a powder of gold, but be full of impurities other than gold, also known as the black stone color shape resembles salt or material gunpowder so that it shines when exposed to direct sunlight, or when you shine a light upon a dark place, You can tell if taper or not by putting it in water in gold and silver Atersban in the bottom of the container and impurities rise to the surface. To separate the gold from the raw material ways to extract gold items vary depending on the difference in suspended sediment by type, there Khtota are necessary to get the gold, namely: how to get raw materials, the process of separating the material gold for the raw material through the transfer of raw materials to private mills to be separated . When prospecting for gold are two processes in the sediment site, where they are drilling for sediment or veins of metal in the ground the same way as prospecting for coal, and the excavators to follow the mineral veins by drilling a passageway vertically into the ground, and some ores are present on the surface of the earth by jackhammers using the bombing, then take the rock that contains the gold and sent to the mills to separate the gold from the rock and impurities, or through hydraulic pumping by pumping aggressively towards the rock that contains the gold who shall Bjrvha about is the grooves to book a gold vessels . Another way is through the leverage which is a machine working to explore for gold by energy have several buckets to be installed on the boat, so that each bucket capacity is approximately 0.2 m, where down the buckets through the arm of the crane and the spin in a circular motion in order to raise gravel from the river bed, and a crane several devices to separate the gold from any other material stuck to it. There are three ways to separate gold from raw materials or water, namely: 1.trivh buoyancy: This method is after blasting, drilling, after Alhosor gold ore, where the extraction of gold by doing grinds raw and sieved and then processed by the buoyancy or flotation to separate the metal. 2. cyanide way: a sophisticated and modern methods, carried out through the raw material sprayed with a solution of cyanide, which dissolves the gold and is passed on granules of carbon present in the electric poles to gold precipitates. 3. The method of carbon pulp: are also using cyanide by mixing the raw material crushed into the water in order to obtain Lubaabah then dissolved in cyanide solution is then added to it carbon molecules Lubaabah to float gold ions on the surface of the pool, and then are removed carbon particles from the pulp and then placed in a hot and caustic cyanide solution to extract the gold from the carbon.
How scan gold
Still wear golden formulated matters favorite among a lot of women in the Arab world, where women boast Balosawr golden rings that adorn parts of her body, especially in the personal and public events, they are evidence of riches for some and a taste with others, especially if it is designed strangely it is remarkable, and there are some women tend to choose simple and soft blocks, while locking other group of them to wearing a lot of pieces on top of each as a sort of social tradition and customary habits as we see in some Gulf and Asian countries and some of the Levant countries.

Ways original distinction gold for fake visual inspection by the naked eye; and by ensuring the presence of seals for gold, where it is printed it from the inside and refers to the purity of gold and sets Carat user at the item type, and can be visually impaired to use a magnifier to make sure that fast, but do not It must be aware that some of the pieces may be old and faded by the seal, and there may be a fake seals similar to the real distinguishes not only specialists in gold. Make sure there are no scratches or peel off the sides of the pieces, though I found it means that painted gold leaf pieces which are not true. Testing biting teeth; where some people can do this test by clicking on a piece of gold teeth, if left bite marks of the teeth on the segment, it means that this piece went native, and the more effects were more profound it shows that the more pure gold. The magnet test work; and this is done by bringing a strong magnet to a piece of gold, if drawn to him it means it is a fake and made of metal other than gold-plated, but only its water, as the gold from metals that are not attracted to a magnet ever. Use test ceramic plate; and it scans or pass a piece of gold over the ceramic plate is coated, the left line segment on a black ceramic This indicates it is a fake piece, but if the fee golden line on the board confirms it as a piece a real and genuine.
How do I know the original gold
After gold a metals and important elements that exist in nature percentage in limited quantities to the rest of the elements such as iron, for example, hence gained the gold value and importance among the people, a component of the chemical elements symbolized by the symbol Au and atomic number 79 in the periodic table, and qualities that element Lin and yellow color and shiny and a little wear and soft and is one of the most elements of the density, and because of all the previous characteristics used cash as currency in ancient States to paper currencies have emerged in the modern era being printed in specialized presses gold, but with the advent of this type of currency, however, gold is still the which gives the value of banknotes in any state which, value of currency derived from the monetary base actress and gold used by the international monetary Fund and the Bank for international settlements.

In addition, gold could be extracted without the intention in doing so when they are extracted metals and other elements as silver, for example. Can distinguish the original gold from other metals in several tests, including mass, as can be measured in two different blocs of the pieces to be tested, but requires be from the same size, when measuring the piece with less mass is hyperbolic non-native. But it was possible to manipulate the mass of the pieces so they look the same real mass. The second method used a stamp or seal, where stamped piece of gold on behalf of the manufacturer, caliber, the HPA can be used for it. You can also biting a piece of gold teeth, the left impact on the gold piece they be original, but the disadvantage of this piece they make an impact can not remove the gold piece, which spoil the landscape. You can also use vinegar in gold does not react with oxygen or with the acid because it has a high density, the event and interacted piece they are counterfeit. Finally, the examiner can use the magnet piece gravitated to him they are not from the original gold. And to mention the majority of the previous methods can be manipulated so you should pay attention.
How can distinguish gold
Since ancient times, until the moment Gold is still the metal more expensive over the centuries, the fact is no scientific reason to do so, but many reckon that because of the color of this metal a near sparkle yellow color (not a full yellowish evidenced by the invention of a new color called golden color and is a non-yellow color is known in all grades). Approaching from the other metals such as copper gold color, for example, and some may wonder how can I distinguish the original gold from other gold imitator, or copper.

There are some ways to check the gold, but as we said no substitute for a thorough examination in their own laboratories, from simple road test flexibility, in gold metal Lin to the extent that pressure strong finger of the hand have an impact on the gold surface, as well as gold reacts with mercury and changes color, so be keen to keep gold from heat parallel, for example, they contain mercury. Gold has a certain intensity are not similar another metal, if you're curious you can take a number of mercury density of the periodic table of elements and work experiences weight balance sensitive to ensure the purity of gold, but requires that a gold subject to that experience is not content posted on the stones because they will affect the density . Standard density aforementioned gorgeous gold is a high density, and Mazmm metals that could cheat the gold is lower than the density, so it can detect counterfeiting immediately.
How to tell Gold ////Uses of gold
Can be sure of gold metal by: the existence of the stamp: a label be located on a piece of gold. The use of the magnet: It can tell if gold adulterated or not by the magnet; where Enkerb magnet of gold if gold was attracted to the magnet it has a ratio of iron. This is one quick and easy ways to detect fraud gold. You can use vinegar; where it is put a piece of gold in the vinegar if turning gold color to black is not gold; because gold does not react with the elements and acids. Use of nitric acid; where it has the ability to solve the metals, but gold does not dissolve in this acid got the erosion it is not gold, but our stomachs least.
