Since its appearance, gold has been the main symbol of wealth and abundance, being linked to the production of coins and money throughout the world. Perhaps the characteristics that give gold its magnanimous importance in society have to do with its flexible density and indestructible malleability.

We must also mention its beauty and radiance, which made it the most coveted metal by empires, kings and queens, and the most used by the religious hierarchy to represent the majesty and might of the gods.

Gold is a chemical element symbolized in the periodic table as Au whose translation from Latin means “bright dawn”. It is a precious metal that has occupied, and occupies within the social and economic relationships of human beings, a meaning of power, wealth and domination.

From the economic sphere, this metal became a reference standard to mark the price of world currencies. Its main use is in jewelry (70% of its extraction); It is followed in importance by employment as a reserve of wealth of the countries, (20% of its extraction); and the remaining 10% is used by industry.

What are the uses for gold?

Gold, being a precision transmitter, is used in medical science as a radioactive agent to apply diagnostic tests that require medicinal radiation.

As a chemical element that allows the course of a reaction to be followed, this metal is used in geological sciences to study the movement of sediments in the oceans and ports.

Its property as a heat transmitter makes it one of the main metals to develop high quality reflectors in the construction of infrared heaters and furnaces, as well as to build heat retainers in industrial processes. It is also widely used in the manufacture of cards, connectors, cables, contacts and other parts.

Finally, we cannot forget that gold plays a fundamental role in the idea of ​​wealth in society. This metal not only creates beautiful jewels that denote money and power, but it is also used in coins and forms of support for entire nations.

Jewelery with gold

For thousands of years, around the world, gold has been used to make jewelry. These have great value, not only economic, but social. Gold garments often attract attention, because historically they are recognized in society as symbols of power and wealth.

About 78% of the world’s gold, whether freshly mined or recycled, is used to make new jewelry. The reasons for its popularity in this area is that it is a very attractive metal; that it is perfectly manageable and moldable; and it is of high strength and durability, as it does not rust.

Gold coins

The use of gold as payment is a system that dates back thousands of years, when coins did not even exist, but it was paid with pieces. This tradition has been going on for years, and although most countries do not currently use gold coins because of their high value, it is still used as a form of backing.

The amount of money that circulates in a country used to be equivalently backed by gold that the nation owned, in this way the value of that particular currency was determined. However, today although many countries have gold reserves, other factors are also taken into account to calculate the value of the currency and the wealth of a country.

Medicinal use of gold

One of the little-known properties of gold is its use as a treatment for certain diseases, whose therapeutic name is chrysotherapy. The therapeutic use of this substance appears in documents as old as the writings of Hippocrates, amplifying its use during the fourteenth century.

However, during the 20th century, interesting studies were carried out where its relevance to certain diseases was exhaustively reviewed, where no clear improvement was seen when applied.

In pharmacology, gold salts have been used to treat diseases such as rheumatoid arthritis, showing improvement in the inflammatory process. However, they have not recorded data that demonstrate the regression or extirpation of the agents that cause the disease.

Another of the difficulties that this type of treatment with gold salts presents is that once it is stopped ingesting, the previously manifest symptoms appear again. For these reasons, these treatments are currently not highly recommended by professionals, although in some places they continue to be popular.

Other uses of gold

In addition to what we have already mentioned above, gold also has other less well known uses. For example, it is widely used in electronic parts, since it is a conductive metal. However, equipment with gold parts usually has a higher cost.

Gold is also used to make awards, medals, and accolades. The metal is molded in a specific way and thus can be obtained from statuettes such as medals of various sizes. These are usually very seen in sports competitions, such as the Olympics, or in artist awards.

There is also the gold bath, which is obtained from a gold foil that is very flexible and is used to cover a certain piece. This not only makes it look more eye-catching, but also protects the item from rust.

Finally, it is also well known that gold is used as teeth. Some years ago it was very popular and denoted wealth and power. Today it is not used as often, but it still represents the same for those who wear it.

Gold properties

Gold is a metal that does not react chemically with the addition of an additive, capable of decomposing into thin sheets and that changes its shape when subjected to pressure. In addition, it is an excellent conductor of electricity and insulator from heat and cold. This metal acquires different yellow tones, depending on its purity.

Gold comes from the deepest rock masses on earth, where there is a very high temperature and pressure. This metal has been extracted from terrestrial geology since 5000 years BC. It is a metal of high resistance, since its melting point to go from its natural state, which is solid, to liquid, is 1064 ° C; and 2856 ° C to become a gaseous state.

This, together with its high capacity to resist corrosive substances, made it the perfect metal to mint coins and make beautiful jewelery.

This metal, when finely powdered, acquires a blackish color; and when it is subjected to processes of fusion to the liquid state, it acquires a reddish or purple color.

It is an excellent electrical and thermal transmitter, which is why the industry has made it the most sought after metal for making precision transmitters.

Where is the gold found?

Gold is found deep underground in the planet’s geological crust. However, due to the action of volcanic eruptions, this metal flows to the surface and forms deposits in mines in the form of caves, caves or caves; and in the open sky, primarily in rivers.

This metal is generally in its pure state. That is, it has no combination with any material. However, on some occasions it can be found mixed with mercury or silver, or with minerals such as skull or sylvanite.

The largest gold and mining deposit in the world is located in Muruntau, Uzbekistan region; following in importance the Pueblo Viejo deposit, in the Dominican Republic, with a reserve of and an annual production of 1,167 million ounces.
