Gold is a natural product that exists in a free state in nature without being artificially synthesized. According to the different sources and the different contents of the content, the content of raw gold and cooked gold. This gold, also known as natural gold, waste gold, and original gold. It is the object of cooked gold. It is a gold that is unlimed from the mine or river base layer and has not been melted and refined. There are two types of gold and ore gold and sand gold. Mine gold, also known as the alleged gold, produced in mines and gold mines. After mining, crushing, and washing, large gold can be picked directly, and the small grains can be dissolved in mercury. Mine gold is mostly accompanied by other metals. Among them, in addition to gold, there are other metals such as silver, platinum, and zinc. Before other metals were proposed, it was called a precursor. The other metal components produced in different mines are different. Therefore, the percentage is different, generally between 50%-90%. The sand gold is produced at the bottom of the river or a low -lying area, so the stone sand is mixed together and washed out of the gold. Sand gold originated in the mine, because the gold ore was exposed to the ground. After a long wind and rain, the rocks collapsed in the north wind, and the gold was separated from the sand and the water. Deposition is a gold -containing layer to form sand gold. The characteristics of sand gold are: different sizes of particles, large as broad beans, small ones like fine sand, different shapes. The color is different due to the height of the formation. More than 90 % of them are red yellow, eight percent of them are pale yellow, and seven become cyan yellow. Matonous gold is the gold that has been smelted and purified by the gold. Generally, the purity is higher and the density is fine. Some can be directly used in industrial production. Common gold bars, blocks, ingots, and various accessories, utensils, gold coins, and industrial gold silk, pieces, boards, etc. Due to the different uses, the required color is different, or because the device is not purified, it is only melted without purity, or the purity of the mention is insufficient, forming a different golden height. People are accustomed to three types: pure gold, red gold, and color gold according to the height. According to the different gold content, it is divided into color gold, mixed gold, and K gold. The gold that reaches a fairly high purity after being purified is called pure gold, which generally refers to gold that reaches more than 99.6%. This and pure gold are close to thought, but due to the different time and local standards, the standards of Chijin are different. The gold sold in the international market reaches 99.6%of Chi Jin. The red gold in the territory is generally between 99.2%-99.6%. It color gold, also known as "secondary gold" and "tide gold", refers to the low color. Due to the different metal content of these gold, the high color is 99%high, and only 30%of the low. If is divided by different metals, gold can be divided into color gold, mixed gold, K gold, etc. The color gold refers to gold only mixed with silver components, regardless of whether it is high or low. There are more color gold, commonly in gold bars, ingots, blocks and various utensils and gold jewelry.
Gold is gold, and the chemical element symbol AU is a soft, golden, corrosive precious metal. Gold is valuable, and the value content is relatively high. The price unit of international gold is US dollar/ounce, and the price unit of my country's gold is Yuan/gram. To participate in future gold investment and get the chance of investment appreciation and value preservation in the gold market, we must understand the role of gold attributes, characteristics and its role in monetary finance. Gold is one of the rare and most precious metals in the metal kingdom. It was mainly used as currency, decoration and jewelry in ancient times. It was the most precious metal. By 1751, platinum was found. It is more difficult to refine, so it is more precious. Therefore, gold is now tied with precious metals from the first precious metal to the status of platinum. However, due to the pure texture of the gold, it has many excellent properties. It is still the most popular precious metal. This is an economics issue. As a rare (relative), gold is not suitable for deterioration (physical and chemical properties) general equivalent objects to replace the value of other items during transactions because it is difficult to obtain (it is difficult to obtain (it is difficult to obtain (it is difficult to obtain (it is difficult to obtain (it is difficult to obtain (it is difficult Mining and refinement) After the value of human labor (the value of the use and the added value of the labor) This it is easy to save (no deterioration) and the quantity (relatively difficult to depreciate) r The itself has value. It is a low -resistant metal that can be conducted. It is not easy to be eroded and it is also its characteristic. It is easy to process (low gold hardness). Some alloys of the raw material or the chip of the computer, etc. but the current role of currency circulation is much greater than the role of the currency, mainly because the appearance of the alloy has greatly replaced the role of gold. /5937
Gold is one of the metals, but the metals in nature are not all metal called alloy, and it is not worth it. Refining is to remove the magazine metal and use the chemical and physical properties of gold.
