Physical Characteristics: Gold is a soft, golden - colored metal with high ductility and corrosion resistance. It has a density of 19.32 g/cm³, a melting point of 1,064.43 °C, and a boiling point of 2,808 °C.

Chemical Characteristics: Gold has very stable chemical properties and does not easily react with other substances. However, it can be corroded by chlorine, fluorine, aqua regia, and cyanides.

Historical Evolution: Gold has held an important position in human history. It was discovered and utilized by humans as early as 10,000 years ago. It was once a symbol of ancient emperors and nobles and was also used in religious ceremonies and decorations.

Cultural Significance: In Latin, gold means "dawn", and in ancient Egyptian writing, it means "the tangible sun", symbolizing light and wealth.

Production and Consumption: Global gold production is mainly concentrated in countries such as China and Australia, and consumption is mainly for jewelry, investment, and industry.

Common methods of gold extraction

1.Gravity beneficiation is a method of differentiating ore concentration according to mineral density. The main equipment used are chute, shaker, jig and short cone cyclone.

2.Flotation is one of the widely used methods to treat vein gold ores in gold concentrators. Flotation processes are also used to treat polymetallic gold-bearing ores, such as gold-copper, gold-lead, etc.

3.The main chemical separation methods are mercury mixing process and cyanide process. Mercury-mixed gold extraction process is economical but pollutes the environment greatly. The cyanide process includes several basic processes, such as cyanide leaching and washing.

4.Heap leaching process has economic benefits. In fact, heap leaching is to heap gold-bearing ores on impermeable sites and leach them with cyanide solution.
