For a person who really wants to reform, we have to accept him and no longer discriminate against him!

To correct one's self-confidence means to correct mistakes and start over. The idiom to reform one's own mistakes was born from a story.

In the early Han Dynasty, there was a very famous medical scientist named Chunyu Yi. Because he was once the chief of Taicang who was in charge of the national warehouse of Qi, people respectfully called him "Cang Gong".

Chunyu Yi loved medical skills when he was young. He became a doctor named Gongsun Guang and asked for advice humbly. Later, he studied medicine from Gongsun Guang's half-mother's brother Gong Chengyangqing.

Gong Chengyang Qing asked Chunyu Yi to put aside all the medical prescriptions he had learned before, and then gave him all the secret recipes he had in charge, and taught him ancient pulse books and various methods of diagnosing diseases.

After learning for two years, Chunyu Yi often cured people's illnesses, and he quickly became a famous doctor. But he liked to travel around, and some powerful people sent him to serve as a doctor. He was afraid that his actions would be bound, so he refused one by one.

For this reason, he also hid his whereabouts, moved his household registration from time to time, and even did not buy property. In this way, it is inevitable that he offends the powerful. When he was the chief of Taicang, someone reported him.

In 167 BC, Chunyu Yi was sentenced to corporal punishment (a torture of tattooing on the face, cutting his nose or cutting his feet). According to regulations, he was sent to Chang'an, Kyoto for punishment.

Surviving corporal punishment is an extremely painful humiliation. Before leaving, Chunyu Yi's five daughters cried loudly. In this uncomfortable situation, Chunyu Yi cursed angrily: "It's a pity that I gave birth to a daughter but not a boy. In the face of urgent difficulties, no one can help me!"

The youngest daughter, Tiying, was both sad and dissatisfied when she heard her father's words. She thought that girls could also save their father's suffering like boys, so she still followed her father to Beijing.

After arriving in Chang'an, Tiying wrote to the court, saying: "When my father was the chief of Taicang in Qi, the people praised him for his integrity and justice. Now that he has to be punished for his crimes, I feel very sad. People are executed and cannot be reborn, and they cannot be reborn after being punished and restored. Even if they want to correct their mistakes and become a new person, there is no way to do so and cannot be as desired. I would rather join the government as a slave to redeem my father's sins so that my father can have the opportunity to correct his mistakes and become a new person."

Tiying's letter was sincere and sad. After reading her letter, Emperor Wen of Han was moved by her spirit of filial piety to her father and voluntarily punishing her father. Finally, he issued an edict to relieve Chunyu Yi of his crime and abolished the corporal punishment this year.

Tiying's extraordinary action not only saved Chunyu Yi from being punished, but also allowed him to re-engage in medicine and devote himself to studying medicine, becoming a famous doctor of a generation.

As the saying goes, prodigal sons will never change their money. Therefore, for those who want to reform themselves and truly become new, we must accept them with the greatest lenient heart, give them opportunities, and help them truly return to society.

Xuchang may have never believed in the monkey before, and he may still be very wary of the monkey in his heart. However, this time, after listening to these words from the monkey, the prejudice against the monkey in Xuchang's heart completely disappeared, and Xuchang fully felt the monkey's intention to reform himself.

If the monkey didn't want to really reform himself, he wouldn't tell him that this stone was a gold ore.

You know, Xuchang just said that there are all such stones deep down. Why did Xuchang come up because there are all such stones below and Xuchang can't dig it anymore, so he had to come up.

A monumental stone brought to Xuchang now is gold ore, which means that the stones below are all gold ore. Moreover, just now, the monkey said that this gold ore is an absolutely rich ore. That is not to say that there is a gold ore deeper than ten meters below.

Gold mines refer to gold ore or gold deposits (mountain). Gold ore is a mineral aggregate with sufficient content of gold and can be used industrially; gold mines are places where gold is obtained through mining operations; gold deposits are industrially utilized gold ore accumulations formed by mineralization.

No metal in the world can intervene in human economic life like gold and have such a significant impact on human society. Its dazzling luster and unparalleled physical and chemical properties have magical and eternal charm.

Although the social status of gold has been in the history of human civilization for thousands of years. It has experienced vicissitudes, ups and downs, and has uncertain rise and fall, it still maintains a sacred halo among the many people and is a wealth that the world pursues.

The crust formed in the early stages of Earth's development has a high gold abundance. Therefore, it can generally represent the Archaeonian greenstone belt composed of early residual crust, especially the combination of mafic and ultramafic volcanic rocks. The gold abundance value is higher than that of various rocks in the crust, and may become the earliest "orch source layer" of gold deposits.

The types of gold deposits are complex and diverse. They mainly include conglomerate type, greenstone belt type, quartz vein type, tough shear belt type, Kalin type, porphyry type, shallow low-temperature hydrothermal type, volcanic rock type, and Cenozoic sand ore.

Gold is in the earth, -6, -6. The abundance of gold in the earth's crust is only 1/10 million of iron and 1/21 of silver. More than 99% of gold on the earth enters the core of the earth.

To sum up, gold has a low abundance value in the earth's crust, and has properties such as sulfur-benefiting, copper-benefiting, iron-benefiting, and high melting point.

To form industrial deposits, gold must be enriched thousands of times, and large ores must be formed, while gold must be enriched thousands, tens of thousands of times, or even higher. It is generally believed that gold mines with huge scale generally have to go through a considerable geological period, and can only be formed through multiple sources, geological tectonic evolution and multiple mineralization superposition.

According to the structural state and gold content of gold in minerals, gold minerals in gold deposits can be divided into three categories: gold minerals, gold-containing minerals and gold-carrying minerals.

The so-called gold mineral refers to gold produced in the form of gold minerals and gold-containing minerals. It is the most important form of gold in nature and the main object of industrial development and utilization.

So far, 98 gold minerals and gold-containing minerals have been found in the world. But only 47 are common, while only more than 10 minerals are directly utilized by industry.

Gold Minerals:

Natural element mineral natural gold (au), containing au>80%.ag<20%; silver gold ore (au; ag), containing au80%~50%.ag20%~50%; gold and silver ore (au; ag), containing au50%~20%.ag50%~80%; platinum-palladium natural gold (au; pt; pd), ~, pt0~, pd0~; silver and copper gold ore (au, cu, ag),,,.

Pure natural gold is rare, and it often contains a certain amount of ag to form au-ag series minerals. There are still different views on the understanding of this series of minerals. Judging from the large number of test results in my country, the chemical composition changes of this series of minerals are continuous. Subspecies can be divided into natural gold, silver gold mines, gold and silver mines and natural silver.

Natural gold can be divided into bright gold, microgold, submicrogold, and sub-electron diffraction gold according to its particle size.

According to the data of Maple Leaf Mining Company, more than half of the rock gold mines are 1 to 5 μm. to 10 mm, among which the particle sizes of 1 to 4 mm are the most common.

The purer natural gold has a thick golden color and its traces (including au, ag).

As the ag content increases, the color and streaks gradually become lighter and the density gradually decreases. The measured pressing hardness vhn50g, ~. As the ag content increases, the vhn value initially increases (natural gold-silver ore), and then decreases (silver ore-natural silver).

Natural gold can be produced in almost all types of gold mines, and is one of the main economic minerals of gold in most deposits, and in some deposits it can become the most important economic mineral of gold.

Although gold and silver ore can be seen in some deposits, the content is generally small, and it has industrial value in only a few deposits or is the main economic mineral of gold and silver. Although natural silver is relatively common, it generally does not contain gold or contains a small amount of au, and only contains a larger amount of gold (~10n%) in some deposits.

There are many co-(companion) minerals such as natural gold, au-ag, and other minerals, which can form a variety of mineral symbiotic combinations, among which the most important symbiotic minerals are quartz and pyrite.

Alloy minerals:

Metal intermetallic gold minerals refer to natural alloy minerals in which two or more metal elements dissolve and form each other in a natural melting state. The main ones are:

(1) Weishan Mine (au.ag)3hg2;

(2) Sifang copper and gold mine cuau.

(3) Gold-silver telluride minerals include tellurium gold ore aute2; tellurium gold ore ag3aute2; tiphenium gold ore, also known as tiphenium gold ore augte4.

(4) Gold and silver selenide minerals Selenide gold and silver mineral ag3au color 2.

(5) Gold and silver bismuth mineral black bismuth gold ore au2 pressure.

(6) Gold, silver, antimonide minerals

(7) Gold and silver sulfide mineral sulfur gold and silver ore (ag3au) 4s2.

Among the above-mentioned gold minerals, natural gold and its variants (silver and gold ore, gold and silver ore) are the most widely distributed. They are also the main industrial minerals of gold.

From the overall perspective of human social development, the 19th century was a very important century. In the thousands of years before the 19th century, humans produced less than 10,000 tons of gold in total, such as only 200 tons of gold in the 100 years in the 18th century.

By the 19th century, gold production had reached a new level, of which 10,000 tons were produced between 1850 and 1900.

After entering the 20th century, in general, the production of gold in the world generally showed an upward trend, and there have been several major increases in production.

In 1900, the world's gold production reached 300 tons per year, the highest annual output in the early 20th century reached 700 tons per year, the highest annual output in the 1930s reached 1300 tons per year, and the highest annual output in the 1960s was close to 1500 tons. In the 1980s, the world's gold production exceeded 2000 tons, and the output has generally increased since the 1990s.

Since the 1990s, the world's gold output has been relatively stable. Since the 21st century, the average world's gold output has remained stable at around 2,600 tons.

Although gold production in some countries has increased, such as Australia-Da Li-A, Missouri and Monkey countries, gold production in South-Africa and the United States is declining.

In addition, due to the long investment cycle of the gold mining industry and high mining costs, according to historical data, the global mineral gold quantity cannot grow rapidly. Therefore, it can be said that the world's gold output will not change much in the next few years and will remain relatively stable.

According to scientists, the gold resources in the earth's crust are about 60 trillion tons, with an average of more than 10,000 tons per capita. However, so far,...

As of 2005, it accounted for about one-600 million of the total reserves, with only 20 grams per person.

The distribution of gold on the earth is very uneven. Although more than 80 countries in the world produce gold, the output of gold produced in different countries varies greatly, and the output of various places is quite uneven. Among them, the top 10 gold-producing countries in the world in 2004 were: South-Fa, the United States, Australia-Da-Li-A, China, the Bear Kingdom, Milu, Canada-Da, Asanicia, Uzbek-Stan, Bab-Asia-Xinji-Nei-Aia. China's gold production has always been ranked fourth in the world.

In 2004, the world produced about 2,600 tons of mineral gold every year, but the ability to achieve this output is the result of continuous exploration and efforts of mankind.

The basic pattern of world gold productivity distribution formed in the 19th century has continued to this day. The gold-producing power formed in the 19th century is still the most important gold-producing country in the world today.

Since 1980, the gold production of South-Africa has shown a steady decline, especially since the 1990s, the decline rate has accelerated slightly, but its gold production is still ranked first among countries in the world;

The gold production in the United States has been in a state of continuous growth, especially since the late 1980s, and it has jumped to second place in the world; while the gold production in Australia-Da Li-Asia has stabilized from the late 1980s to the early 1990s, and the gold production has stabilized and has not changed much.

The major gold-producing countries in the world include: South Africa, the United States, Australia, Greater Italy, the United States, Canada, Greater China, etc. However, the world's gold production pattern has also changed over the past century, especially the United States, Africa and India's gold production has declined, while the gold production in South America's Milu, Agentine and East South Asia has increased significantly, among which Latin America's gold production has accounted for 14% of the world.

It can be said that with the development of society, gold mining is becoming more and more prosperous! (To be continued, please search for astronomy, novels are better, updated and faster!
