Development history of gold mine:

From the overall development of human society,19th century is a very important century.

In the thousands of years before the19th century, human beings produced less than 10000 tons of gold, for example, in the18th century, only 200 tons of gold were produced.

By the19th century, gold production reached a new level. During the period of 100, the gold produced reached 1. 1.5 million tons, 57.5 times that of18th century, in which 1.850- 1.900 years were used.

After entering the 20th century, on the whole, the world's gold output showed an upward trend, and there were several times when the output increased greatly.

1900, the world gold output reached 300 tons/year, 700 tons/year in the early 20th century, 1300 tons/year in the 1930s, and nearly 1500 tons in the 1960s. In the 1980s, the world gold output exceeded 2,000 tons, and the overall output has been increasing since the 1990s.

Since the 1990s, the world gold output has been relatively stable, and the average world gold output has been stable at around 2,600 tons since the 20th century.

Although the gold production of some countries has increased, such as Australia, Peru and Indonesia, the gold production of South Africa, the United States and other major gold producing countries is declining.

In addition, due to the long investment cycle and high mining cost in the gold mining industry.

From the historical data, it is impossible for the global mineral gold to grow rapidly.

Therefore, we believe that the world gold output will not change greatly in the next few years and will remain relatively stable.

According to scientists' calculations, there are about 6 trillion tons of gold resources in the earth's crust, and the per capita income exceeds 1000 tons.

However, up to now, the world's proven gold resources are only 89,000 tons, with a reserve base of 77,000 tons and a reserve of 48,000 tons.

By the end of 2005, the gold mined by human beings was only 1.25 million tons, accounting for about one-sixth of the total reserves, and the average per capita was only 20 grams.

Gold is unevenly distributed on the earth. Although there are more than 80 countries producing gold in the world, the domestic gold production varies greatly, but the gold production in different places is quite uneven. In 2004, the top 65,438+00 gold producers in the world were: South Africa, the United States, Australia, China, Russia, Peru, Canada, Indonesia, Uzbekistan and Papua New Guinea.

China's gold production has ranked fourth in the world.

In 2004, South Africa, Australia and the United States accounted for 13.9%, 10.6% and 10.2% of the world's total gold output respectively. China's gold production has reached 8.6%.

The world mines about 2600 tons of gold every year, but reaching this output is the result of continuous exploration and efforts of mankind.

/kloc-the basic pattern of the world gold productivity distribution formed in the 0/9th century continues to this day, and the gold-producing countries formed in the 0/9th century are still the most important gold-producing countries in the world today.

Since 1980, South Africa's gold production has been steadily declining, especially after the 1990s, with a slight acceleration, but its gold production still ranks first in the world. The gold output of the United States has been in a state of continuous growth, especially since the late 1980 s, which has jumped to the second place in the world; However, from the late 1980s to the early 1990s, Australia's gold production tended to be stable with little change.

Major gold producers in the world: South Africa, the United States, Australia, Russia, Canada and China.

However, in the past century, some changes have taken place in the world gold production pattern, especially in the United States and Africa, while the gold production in Peru, Argentina and Southeast Asia in South America has increased significantly. Among them, Latin America's gold production has accounted for 14% of the world.

Gold mine refers to gold mine or gold deposit (mountain).

Gold ore is a mineral with sufficient gold content and can be used in industry. Gold mines are places where gold is obtained through mining operations; Gold deposit is an industrial accumulation of gold deposits with a certain scale formed by mineralization.

There is no metal in the world that can continuously interfere with human economic life like gold and have such a huge impact on human society.

Its dazzling luster and unparalleled physical and chemical characteristics have magical eternal charm.

Although the social status of gold has experienced vicissitudes, ups and downs and ups and downs in thousands of years of human civilization, it still maintains a sacred aura in many people's hearts and is the wealth pursued by the world.
