Preface
With the birth of the world's first gold currency, it also revolutionized the global monetary system.
After the changes of the times, developed countries such as the United Kingdom, the United States, and France have adopted the BRICS standard currency circulation.
This shows that gold is a symbol of wealth in the world today.
And in one part of South Africa, half of the world's gold pits are hidden.
Why, then, is there the chosen son of gold, and what is the secret it hides?
Where does the gold on earth come from?
Originally, there was no such thing as "gold" on Earth.
During the chaotic period of the universe, the whole world only had "hydrogen", and after a long period of nuclear fusion, other different metal elements were slowly formed.
In the process of nuclear fusion, the demand for cosmic energy is increasing, and the phenomenon of meteorite explosions falling to the ground has occurred.
As the stars of different kinds of elements bombarded the earth in turn, the earth, which was still in a lava state at that time, melted countless small celestial bodies and combined them to bury them deep under the rock layers.
Eventually, through the movement of the earth's crust, "gold" took root on the earth.
As time passed, more and more volcanic eruptions occurred on Earth, and all kinds of metal elements were exposed, including jade, masonry, silver, and gold.
Later, after artificial mining and excavation, various metal ores became known to mankind.
Due to the small amount and limited content of gold on the earth, the gold element has been known as "ten thousand taels of gold" since ancient times, and it is also one of the most valuable elements in the world.
The reason why a gold pit can be formed
Before 1886, the Transvaal in South Africa's "Witwatersrand Plateau" was an ordinary provincial town, a natural highland area with an average altitude of 1,500 to 1,800 meters.
With the excavation of a large pit in the area, the Transvaal gradually developed a huge gold mine, and since then, the Transvaal has become so famous that South African coins have been defined by the word "rand".
So, what are the reasons for the formation of gold in the Transvaal? It goes back 2.6 billion years.
At that time, the Transvaal rock formations were very deep, and after many natural activities such as crustal movements, it gradually changed from a sea to a plateau.
With geological changes, the rocks of the Transvaal have undergone many changes in minerals.
Later, meteorites in the universe fell here, and some of the "gold" elements in it fell at the mouth of the river, and some were buried in the ground.
Over the years, the Transvaal developed a mega gold mine, which is now known as the "Rand Central Gold Mine".
Introduction to the Rand Central Gold Mine
Although South Africa is considered by many to be poor, it has three major gold mines in the world, including the world's most famous Rand Central gold mine, so South Africa is known as the "Kingdom of Gold".
Initially, the Rand Central Gold Mine was discovered by a local farmer south of the plateau, and after word spread about it, many experts came to the Transvaal to study the mine.
After exploration, it was found that this large pit actually contained half of the world's gold, and almost all of the gold elements under the mountain range.
After that, the state began to call for excavations in the mountain range, and the mountain where the gold was discovered was dubbed the "Rand Central Mining District".
Today, the local people have been digging at the Rand Central Gold Mine for more than 100 years, however, the gold from the Rand Central Gold Mine has been mined for a long time, and nearly 35,000 tons of gold have been used, and there are still 18,000 tons of gold reserves.
In addition, the large amount of gold in the Rand Central Gold Mine is the first in the world, and its storage capacity is as high as 52% of the global total.
After continuous excavation in the area, the Rand Central Gold Mine has been turned into a large crater with a depth of 3,600 meters, which from a distance looks like the abyssal crater of the mountains.
The Rand Central Gold Mine not only has a large gold reserve, but also has a first-class gold content ratio in the world.
Judging from the current data, the general gold mine is in a dispersed state in the distribution of gold, which means that the gold content in a ton of ore is only a few grams, because it is not easy to refine, so the price of gold is very high.
The gold element of the Rand Central Gold Mine is different from the gold mines of other countries, its one ton of ore, the gold content is nearly 10 grams, and some ores can be refined 15 grams.
As the world's largest gold mining area, the Rand Central Gold Mine produces high-quality gold that countless people yearn for.
In addition, the Witwatersrand Plateau is not only home to the Rand Central Gold Mine, which is the backbone of the economy, but also the raw material for nuclear energy, uranium ore.
The world's luckiest Witwatersrand plateau will surely have great developments in the future.
Uses of gold
In everyday life, it is generally believed that gold can only be sold as jewellery or bullion.
In fact, gold is still a good raw material for manufacturing, such as in medical devices, flight creation, electronic products and other fields, gold plays a pivotal role.
In ancient times, gold was used to poison sharp weapons, people as long as oral gold, soon will die, this is because gold contains mercury, copper and other trace elements, and then react with the human intestines, causing poisoning.
In the modern era of rapid development of science and technology, the refining technology of gold has been very mature, so the purity of gold is very high, and the content of mercury and copper is very low, which will no longer cause damage to the human body.
Therefore, gold is used in medical devices, and people can make stents or small parts implanted in the human body, which can save the lives of many patients.
In addition to this, gold is also used in space probes, where it protects the probe from rays in outer space.
Because gold is not perishable, it is very common to use it in electronic products, and gold has become an essential component in electronic devices.
However, the gold element in the world is limited, it can not be inexhaustible, if one day the gold on the earth is exhausted, the impact on human beings will be very huge.
In the process of smelting gold, pollutants such as waste gas and wastewater will be generated, resulting in environmental pollution.
epilogue
When human beings use the material materials in nature, they should not only focus on short-term interests, but also take a long-term view.
You know, such a beautiful earth can't help but be plundered wantonly.
The ultimate fate of the earth is in the hands of each and every one of us, and we must love it.
