Gold and precious metals

Consisting of three metals precious metals:

1. gold.

 

2. silver.

 

3. Platinum.

Gold and precious metals

These minerals are mined from the ground and not to any interference in human composition.
It was named the three precious metals, because they have some of the important characteristics that distinguish it from some other metals. Such as public acceptance of these minerals in people without other metals to make it rank high in minerals, leading to increased demand without other

metals.

Gold is a precious metal, a chemical element with the symbol Au symbol and atomic number 79 on the periodic table. A lane and brilliant yellow color, use as a criticism when many peoples and civilizations and Nations, as it is used in jewellery and gems. Exists in nature in the form of granules within rocks in riverbeds, or in the form of veins in the ground, and often there are gold with other metals such as copper and lead, and discovered the largest block of gold in Australia in 1896 and the weight 2 280 an ounce, gold has the advantage of low wear and smoothness as that of more chemical elements.

Uses of gold
The unique properties of gold of his softness and clouds and diacritics, its resistance to corrosion, making it suitable for many purposes it is mixed with other metals such as copper or silver or nickel to get stronger, and alloys with Platinum within industrial manufacturing of IAF because they are very resistant to chemicals, that gold is the metal of choice in many areas such as:
In ornamental jewelry:
More use of gold in jewelry decorations in the so-called yellow gold, this is done by mixing gold with copper, silver and zinc in varying ratios result in multiple gold bullets, gold purity is measured in parts (part a) or caliber as American standard, for example, the degree of purity 1000 corresponding caliber 24, purity 875 corresponding caliber 12, while 750 corresponding caliber 18, generally the color tends to pallor whenever you lose any caliber number decreased the amount of gold in the The alloy. Either white gold is gold mixed with Tin or palladium to make it white and gold used for jewelry sets are usually white.
In medicine:
Used in dentistry as his softness and resistance to corrosion in the mouth.
Gold solution is also used in the treatment of rheumatism and bone infections

How has gold colors
We have known that pure gold is not if we are to do a pure gold on a busy (ghoishh or Kit, for example) without can add any extras, this is extremely difficult, and why that gold metal metal road prone to distorted by any pressure is so other metals are added to increase secular impart stiffness to a variety to crafts and thin without fear from the deformity if any pressure is , It is worth mentioning here that the additions of other metals added to gold for the purpose of increasing its hardiness have a tremendous impact on the color gold, melting point, and with the addition of other metals to gold for the purpose of acquisition of Crucian Gold needed in the formation of various colors have gone so that if we add other metals to gold would be to calculate the percentage of gold in the alloy and the gold rate will vary depending on the percentage of additive metals known as gold colors , If your caliber is a wrought gold
Colors of gold
Multiple gold colors depending on the ratio of minerals added to gold as explained above, the maximum color that we have a pure gold (raw) and is 24 ratio of gold color in this caliber are 1019-gone, and the reduction and increase the proportion of metals added in offset from the following colors:
• Gold karat 21 KARAT or 875:
Karat 24 equates 875 points from the alloy of gold 875 per thousand gold NET, 125 thousand other metals such as copper and silver.
• 18 KARAT gold or 750:
And means that the alloy of gold of 750 thousand gold NET, and other minerals 250 thousand.
• 22 KARAT or carat gold 916.66:
And is equal to 916.66 points from net went, but infrequent in trading
And it should be noted that there is a (14) and caliber (9) not to help the Ministry of Commerce of precious metals and gems prohibits dealing in the import and manufacture of gold jewellery in 18 karat (750). Where is low caliber, although use of such calibre in other States for example bullet 8 ‘ 9 used in the United States, and 12 and 14 is used in Italy, and 17 in Pakistan, but all these bullets are Arabic States and only regular bullets only 24, 22, 21, 18. And below that is a low bullet

 

Important facts
Ounce, Troy ounce is a unit of weight of gold, equivalent to 31 119 grams gold

Kilogram of pure gold if we have broken into an ounce equivalent 32.15 oz

Bullets and ratios are as follows:

24 percent pure gold, or his purity is 999.9 from gone

Caliber 22 percentage of pure gold are 916.6 from gone

NET-21 gold ratio is 875 thousand gold

18 percentage of pure gold which is 750 thousand gold
How to select sale price
The sale price to the consumer is determined on the following basis:

Pricing grams (net).

Industrial wages which vary according to the quality of the works and presents.

Add a profit margin, i.e.:

Equivalent sale price to the consumer = price grams (net) + industrial wages + profit margin.
Factors affecting gold price worldwide
Economic crises, international tension and wars (correlation).
Supply factors (inverse relationship), and application (correlation).
The level of economic activity, economic growth and inflation (correlation).
Interest rate changes (inverse relationship)

Gold color:
The pure gold 24 Karat and 24 KARAT, writes and is a metaphor for the purity of gold equivalent to 1000 points, but the purity of these non-existent realistically and closest what you see written on the ounces of gold and is 1019, and carat fineness is determined, either purity is determined by points.
There are gold colors represents the gold standard, and reflect the ratio of mixing gold ore with other metals, and are defined by the Ministry of Commerce.
And so the sale price of gold “is influenced by the following:

• Gold price in global stock markets.

• The local exchange rate.

• Cost of production (industrial wages (

• Profit margin.

On the other hand, industrial wages and profit margin are influenced by the following:

Competing policies.

The average incomes of consumers
Factors affecting gold price worldwide

Economic crises, international tension and wars (correlation).
Supply factors (inverse relationship), and application (correlation).
The level of economic activity, economic growth and inflation (correlation).
Interest rate changes (inverse relationship)
