999 Gold

Gold mined in deposits is never in a perfectly pure form, without impurities from other inclusions. It is a quantitative indicator of the proportion of precious metal in the alloy that is the criterion for establishing a sample. The higher the content of the main element - gold, the higher the indicator is assigned. Assigned sample 999 indicates the highest gold content in the alloy with a minimum of foreign elements, which, accordingly, determines the cost of the ingot.

In its pure form, gold is a rather soft metal, easily susceptible to mechanical damage. To preserve the noble properties in jewelry production, it is supplemented with various contents of stable elements called ligatures. Mostly copper, silver, palladium, nickel, zinc, platinum are added. The initial gold is supplemented by the properties of inclusions, becomes immune to deformation and scratches.

To determine the quantitative composition of the ligature, karat and metric systems are used. In different periods of history, systems for measuring gold in troy ounces and grams were used. So, 1/24 of the noble metal contained in the alloy is 1 carat. A sample of 999.9 in the metric system is the purest gold of 24 carats.

Today in Russia such a metric system is adopted. It shows the number of grams of precious metal per 1 kg of alloy. A sample determines the amount of gold expressed in thousandths. The reciprocal of the sample is the amount of ligature.

Sample gold 999, as a noble metal, has various mechanical and physical properties due to its composition. Bank ingots of the highest standard look very bright, have a rich yellow color, because the presence of impurities in them is minimal. Their manufacture is associated with a density indicator, as one of the most important characteristics in the gold mining industry in the manufacture of such ingots. This parameter is very high for gold, amounting to 19.32 g / cm3.

Good ductility and high ductility made it a universal metal for jewelry production. Specific gravity allows you to make a foil of gold with an area of ​​1 square. meter or make a narrow long wire. A mixture of metals with close values ​​of this indicator gives the highest quality of smelted ingots.

Gold goes into a liquid state when exposed to a melting point of about 1070 degrees Celsius. The boiling point is even higher - 2947 degrees. When heated, 999 gold behaves similarly to other samples. The color changes to light green, the metal fumes will be yellow-green.

Besides, It should be noted the low hardness of the precious metal. In accordance with the internationally accepted Mohs scale, its indicator is 2.5-3.0 points.

The softness of gold makes it difficult to work with precious metals. Jewelers solve this problem by introducing various alloys into the alloy, which change the characteristics of the output.

Physical properties of 999 gold and smelting of ingots from it are reflected in the list of GOST requirements. Each ingot will weigh as much as the standard defines, the document regulates the maximum weight deviation standards. The ingot shall not have cracks or inclusions of foreign elements. Each ingot is assigned a unique number; it is marked and registered with the Gokhran of Russia.

Noble metal is mined from ore in placer deposits. Basically, this process is carried out by large enterprises or artels that have state accreditation and strictly comply with the legislation in this area. The production process for producing gold with a breakdown of 999 is called refining.

There are several mining methods:

• gold ore as a source of precious metal is first calcined, then zinc is added and gold is separated using sulfuric acid;
• during amalgamation, the gold ore is crushed, a solution of sodium cyanide is introduced, which is then precipitated with zinc;
• well-known and the most non-technological screening method is based on the use of differences in the specific gravity of the rock, but with this option there is a danger of too much metal loss.

Industrial refining consists of several rather complex operations.. Among the varieties of the process, it is possible to distinguish: chemical, wet or dry refining, saltpeter refining, crafting, the use of iron sulfate and hydrazine hydrochloride, and the electrolytic method.

999 gold is used primarily in banking, jewelry and some industrial sectors.

Higher-grade ingots are made for storage as a gold and foreign exchange reserve in many countries. Due to the high plasticity of the metal, the small ingots with individual marking are sealed in transparent cases, which allows them to maintain perfect condition for a long time.

Large banks can offer bars of various weights in their pure form. Buying bullion is a fairly popular method of investing for a long time. According to the analysis, the price of gold is only growing for several years, so customers of financial institutions that have made a bet on investing in gold in the long run have chances for a good increase in profitability.

Ingots with marking 999 weighing from 1 kg are used by central banks of the world. Used to fill state funds, gold bullion is made by refining exclusively from an element of high purity.

Fine gold jewelers do not use too often. The problem is the properties of the metal, which do not allow creating artistic decorations of complex weaving or exquisite design.

999 gold items are 24 carats in accordance with the international standard. This immediately affects their price. Very expensive and rarely found jewelry creations can get deformed even from the smallest impact. Experts advise storing such creations in wooden or metal boxes.

Besides, working with this type of metal is quite difficult technically. Therefore, jewelers prefer to use lower-grade precious metals 750 and 585 in the production of gold products, which provide durable material.

Quotes for 999 gold prices are determined by fundamental economic factors and the form of acquisition of precious metals. Financial analysts identify several trends that determine the value of precious metals:

• dynamics of investment demand;
• the impact of state banks on price fluctuations;
• change in the volume of gold mined around the world;
• the impact of demand from the jewelry industry and industry.

A common unit of measure for the mass of gold in the world is taken as a troy ounce. Translated into grams, this is 31.1 grams per ounce. The cost of one gram over the past 3 years is within 2300 rubles. This makes investing in bullion an excellent investment tool. The mined volume of gold for the production of the highest grade is limited, so rarity determines the market high cost. Commercial procurement allows one to predict the demand for such gold.

The cost of a gram of precious metal depends on the dollar. The decline in currency quotes is forcing investors to look for more suitable investment methods and shift to gold, which stimulates the global price of the metal.

The Russian gold and foreign exchange market forms the dependence of the price of 999 gold samples on the weight of the ingot. In addition, until recently, VAT was established on bullion from precious metals - their purchase at banks also increased the final purchase price. Therefore, a rather simple solution was the opportunity to open anonymized accounts.

You can also buy gold coins. Most of them have an interesting design and even inlaid with jewelry stones. Such a coin, even after decades, will delight its owner not only with beauty, but also with a solid increase in collection value.

999 gold bars or coins should be handled as carefully as possible. After all, the preservation of presentation is guaranteed by the high price in case of reverse sale. This is no less important than the exclusivity of the circulation or the parameters of the ingot. A bank or other buyer may not accept a gold product if there are chips or scratches. In this case, an ingot or coin will be sold at the price of scrap.

For metal with this marking, there are small features of care. The basic rule is maintain proper product operation. You need to store them in a case, protect them from any mechanical impact, never take them with sharp objects, avoid pressure, polish, or clean using special pastes. It is recommended to polish gold items with a small napkin made of suede or cloth. A more correct way of cleaning is to give the gold jewel to a jeweler for professional care.

Any gold item should not be taken with you to visit gyms, and especially swimming pools. Chlorine can corrode metal.

The key to the long service of gold jewelry is to take care of them.. Indeed, over time, they become antiques, the value of which is only growing.
