Origin of gold

Gold is the gold element in the earth's core that is brought to the mantle and crust. After ocean precipitation and regional metamorphism, activation migration and rock gold oxidation, it is finally transported by river water. , the gold sand mine formed in the stable water of the river is a rare and precious metal. It has a soft texture, strong malleability and ductility, good corrosion resistance, and is widely used.

Gold is gold with the chemical symbol Au

The name Au comes from Aurora, the goddess of dawn in Roman mythology, which means shining dawn. The ancient Incas regarded gold as the sun. Beads of sweat, the Pharaoh of ancient Egypt insisted on being buried in gold, the flesh of God.

The role of gold

Gold has good ductility and strong malleability. It is usually made into gold foil, micron gold wire and gold powder, and is plated on the surface of other metals for embellishment. Gold has good electrical and thermal conductivity and strong oxidation resistance. It is usually used in the production of electronic products and plays a significant role in the industrial construction of modern society.
