gold
Gold is a precious metal yellow metal, and a chemical element symbolized by the symbol (Au), and is called the non-factory term of the term, and gold is distinguished from other minerals not affected by the factors of the environment or weather conditions remains conservative shape and value does not change over time and gold characteristics. Characteristics are the most important: flexibility, ability to form, and luster.
Gold is distributed in nature with other metals, perhaps the most important copper and lead, which mixed with different proportions, and gold in the form of small granules downstream of rivers and floods, and in the rocks, as the form of veins in the ground.
Whereabouts of gold
Gold is a valuable element, but it exists in nature in very small quantities, and for this reason is attributed to the high price, in addition to the difficulties of extraction, and when searching for gold in its places we find two images:
Primary precipitation
The primary deposits of gold are often present in hot and cold water sources, but the most important ones are hot. Here, gold is mixed with other mineral elements, most notably pyrite, sulfur, tourmaline, and mollendine. These minerals are easily separated from gold once exposed to environmental factors and atmospheric conditions. Precipitates in the course of floods and rivers.
Congestion deposits
Congestion deposits are very large in the United States of America, particularly the states of Alaska, Colorado and California, as well as in Siberia, Australia, and the Ontario District of Canada. South Africa, especially the RAND region, accounts for 40% of the world’s gold production, while the largest gold ore extracted from Australia was 2.280 ounces.
Gold Uses
- It was used by many peoples, ancient and modern civilizations, but the oldest and largest use of gold was in the Pharaonic civilization. They used it to build the walls of the royal chambers. They made the coffins of their kings, their carriages, and a coin. The most beautiful masks known to mankind; being made from the pure gold of Pharaoh Tutankhamun, has expanded the circle of uses of gold at the present time to include:
- A monetary base by the International Monetary Fund (IAF) and the Bank for International Settlements.
- Manufacture of jewels.
- Electronics industry, where a relatively small amount of gold is used in each of the modern electronic devices, such as mobile phones, calculators, PDAs, GPS devices, computers and television.
- It is used in medicine, especially radioactive gold (198) to treat some types of cancers, and is also used in the treatment of rheumatism, osteoarthritis, in addition to its use for making teeth; because of its resistance to corrosion.
