4 thoughts on “What is gold?”

  1. Gold jewelry can be seen everywhere in the mall, especially the guests on the shop can be seen on holidays. From ancient times to the present, it seems that everyone has a particularly love of gold jewelry, and gold cannot be eaten or worn. What is the use?
    Gold, a kind of metal
    Gold is a single matter (AU) for chemical elements (AU). Because it is commonly called gold, it is also called gold. Different from most metals, the chemical properties of gold are extremely stable. Whether it is placed at high temperature or under strong corrosion, it will not be destroyed. "Real gold is not afraid of fire" is the stability of gold.
    A as a metal, gold is a relatively soft one. Those who have bought sufficient gold jewelry know that they will deforize when they pinch their bracelets. In addition to the soft texture, gold also has good ductility, and 0.5g gold can pull out 160 meters long gold silk. It can be done whether it is making gold foil or sloping gold.
    How is the extremely stable and good ductivity metal such as gold?
    The volcanic eruption has brought disasters while also bringing a lot of golden elements. Through the volcanic eruption, gold elements flowed out of the ground nucleus, stagnant in the mantle and the crust, and finally formed gold mines. The weathering in nature and the washing of the river caused the geology to be destroyed, but because of gold and its stability, it slowly deposited into a sand gold mine. "Golden Gold" is to screen gold in the sandy texture of the river. Of course, not every river can gold, only very few places contain sand gold. It is mainly distributed in Jinsha River, Heilongjiang, Zijiang and other places.
    It part of the gold ore under the influence of geology has become a yellow iron ore, a flash zinc ore, etc., and the gold and minerals are sealed in nature. my country's Shandong region is rich in gold.
    gold exists in nature, but do you know where gold is usually? The gold mines that can be mined are usually located in the crust, and the content is very scarce, only one millionth. Even the gold ore formed, the gold that can be truly mined is extremely scarce. my country's gold ore is usually 2G/ton, which means that only 2G gold can be refined in a ton of ore.
    The mines with less gold content may only be refined by 0.5g. Many gold mines are existing in rock gold ore, which can be exploited or mined under the well. However, filling method is usually used to prevent the ground from collapse. To dig a ton of ore, you need to fill the vacancy in sand and cement to invest a huge investment.
    . Sand gold is relatively simpler than mining gold mines. The density of gold and sand is used to buy gold from the sand through artificial or machines. If you are lucky, a piece of gold may be more than ten grams or hundreds of grams, and you may not be able to get anything. A large amount of sand has very few gold, but it is much lower than the cost of mining.
    Why do you like gold?
    In addition to the stable price, it is difficult to depreciate. It is one of the reasons for everyone's favorite. The cause of gold is special, the output is small and cannot be synthesized by manual synthesis. The difficulty of mining is also very difficult, even if gold is in the mantle layer, it is difficult to minimize. "Things are rare" gold are rare metals.
    Callow is very popular because of the special properties of its material to be processed into a variety of beautiful jewelry and crafts. Especially in ancient China, gold was once regarded as a symbol of power. The emperor's dragon robes and phoenix crowns were made of gold rust or gold. Due to technical restrictions, the production of gold is scarce, and the price is expensive, and ordinary people have almost no gold.
    5, no more than 100 pieces of 10 pieces, no 100 yuan makes people look like. Compared with copper and silver currency, natural gold is also more loved. Until now, jewelry such as gold earrings, necklaces, rings, bracelets, etc. are very popular. Since ancient times, gold has been very popular.
    Due to the stable nature of gold, it generally does not change color and oxidation, and has a good preservation value gradually becoming a general currency. "Currency War" records that it was previously used as currency such as copper and iron silver. Later, due to the strong stability of gold and rare, it became the most valuable currency.
    If World Gold Association's 2022 data shows that there are 34904.76 tons of gold reserves in the world, and gold has also become an important role in the country's economic guarantee. Especially in the economic instability and the war, the price of gold has always been high, and once became the most valuable "stocking".
    This in the Chinese market, gold is deeply loved
    Gold is not only popular in the international market, but also loved in the Chinese market. According to statistics, traditional gold jewelry revenue in 2020 was as high as 169.874 billion yuan, and the gold jewelry consumed in China in 2021 reached 711.29 tons, an increase of 45%compared with 2020. China is also a large consumer country, and it is more popular compared to diamonds and emerald gold.
    The use of gold is wide
    Gold can not only be used for jewelry, but also hoarded as currency. It also plays an important role in other industries. According to statistics in 2016, the gold used to dental is 18 tons. Due to its good stability, gold has good compatibility with the human body, and it is also widely used in dentistry. Golden porcelain teeth will not be aging or oxidized. The strength and toughness are better. It can not be used for a long time.
    Gold has high -tech, which is unmatched by any other materials. It can withstand small current for a long time without being corroded and will not change due to environmental changes and temperature changes. This inertia is used in electronic devices, and its performance will be extremely stable.
    According to data, 6%of gold is used in the science and technology sector. In high precision instruments, gold is also the raw material. Many people don't know that the most common mobile phones in our daily life contain gold. For example, gold is used in Apple and Samsung mobile phones, and gold is widely used in domestic mobile phones. However, the gold content in the mobile phone is small. More than 40 mobile phones may be refined by 1G. The content is low but its role is huge. In addition to mobile phones, many electronic products have been widely used in gold.
    In addition to the electronics industry, gold also plays a huge role in the aerospace industry. The U.S. Aerospace Administration proposes that because gold has good infrared launching, it can be applied to space telescopes. Gold is used on the equipment such as spacecraft, measurement, remote sensing, positioning, etc., and gold has become an irreplaceable special material.
    The reason why gold has been pursued by many people for a long time is not only because of its rare, but also because gold in the long history has become a common currency in the world, but also has its unspeakable value and application. Gold will still occupy an important role in the future market and will not be drowned.

  2. Gold (GOLD) is a single form of chemical element gold (AU). It is a soft, golden, corrosive precious metal. Gold is one of the rare, precious and extremely valued metals. Internationally, gold is generally based on ounces. In ancient China, "two" was used as a gold unit, and it was a very important metal. It is not only a special currency for reserves and investment, but also an important material for the jewelry, electronics, modern communications, aerospace and air industry and other departments.

  3. Pure gold is a metal with bright luster, red, soft, density, high density, and ductility. It is one of the rare, precious and extremely valued metals. At the same time, it is also an important material for the jewelry, electronics industry, modern communication, aerospace and air industry and other departments.

  4. Take a look at the explanation of gold for you: Gold scientific saying is the single -quality form of chemical element gold (chemical element symbol AU), which is a soft, golden, corrosive precious metal. Internationally, gold is generally based on ounces. In ancient China, "Two" was used as a gold unit. Now we use international public grams. For example, there will be a lamp sign in gold shops to show today. Equal 31.103481 grams. The chemical symbol of gold is AU, and the English code in finance is XAU or GOLD. The name of the AU comes from a story of the goddess of dawn in Roman mythology, and it means dawn.
    The chemical stability of gold is very high, it is not easy to have chemical reactions with other substances, and do not have to worry about oxidation and discoloration. Even in the melting state, it will not be oxidized and discolored. After cooling, the golden light is shining; the density is large, the feel is heavy, and the amount of weight is particularly weight. The toughness and ductility are very good.
