  1. You can dig a place in the carbonate rock.
    In carbonate rocks, which account for 36 97%of the total amount of gold. Through the above studies, it expands the visual look of the mine and increases the reserves.
    It what needs to be explained is that privately cannot develop mineral resources.
    In the "Constitution of the People's Republic of China"
    The natural resources such as mine collection, water flow, forests, mountains, grasslands, wasteland, beaches, etc., all of which are owned by the country; Except for forests and mountains, grasslands, wasteland, beaches.
    The country to protect the reasonable use of natural resources and protect precious animals and plants. No organization or individuals are prohibited from occupying or destroying natural resources by any means.

    is scarce in gold prices. In the earth crust, only one billionth is gold; Low, its billion -dollar rate is only 0.1 to 0.2. Many people claim to be able to obtain gold from the seawater, but until now, no one can really achieve it. By the 21st century, people still have no way to extract gold from the sea.

    Since 1880, South Africa has been the main source of gold supply in the world. In 1970, South Africa's gold production accounted for 79 % of the world's supply, about 1,000 tons, but only 272 tons in 2007. China produced 276 tons of gold in 2007, replacing South Africa as the world's largest gold producer. Other major gold producers include the United States, Australia, Russia and Peru.

  2. Where can gold be dug
    Gold (GOLD) is a single -quality form of chemical element gold (chemical element symbol AU). It is a soft, golden, corrosive precious metal. Gold is one of the rare, precious and most valued metals. Internationally, gold is generally based on ounces, and ancient China was used as a gold unit. 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.

    The chemical symbols of gold are AU, and the English code in finance is XAU or GOLD. The name of the AU comes from a story of Aurora, a goddess of dawn in Roman mythology, means shining dawn.

    The average content of gold in the crust is about 1.1 million % (0.0011ppm), and the content in the seawater is about 100 billion % (0.00001ppm). The billion-year-old crustal movement and geological changes have made gold elements rich into gold mines. The quality of gold ore with general industrial value is 2-3 grams/ton. /Ton, there is also a gold, the smallest single piece, the largest tens of kilograms, and the rare large pieces of gold hundreds of kilograms. Because of some dog heads, commonly known as dog head gold, Indian scientists have found two nearly 2.5 pieces of nearly 2.5 Tons of dog head gold; poor ore at 0.1-1 grams/ton. The level of metallurgical technology has industrial mining value.

    The pure gold in nature, often contains biocontonistic elements such as silver, copper, iron, tadpoles, platinum, nickel, nickel, serenity, and crickets. Natural gold contains 15%of silver Those with gold ore, more than 20%of copper-containing copper gold ore, 5-11%of them are called 钯 矿 矿 矿 钯 金 金 金 金 金 金 金 铋 铋 铋 铋 铋 铋 铋 铋 铋 铋 铋 铋 金 金 金 金 金 金 金 铋 铋.

    The gold has sulfur, often coexisting with sulfide such as pyrine, poison sand, square lead ore, and 锑 锑 ore; Chemicals.
