Gold is one of the most desired and useful metals in the world. Not only does it have a beautiful shape and sculpture, but the precious yellow metal conducts electricity and does not tarnish. These qualities make it the preferred metal for industrial, medical and technological industries, just to name a few. Of all the minerals extracted from Earth, none is more useful than gold.
. Gold conducts electricity, it does not tarnish, it is very easy to work with, it can be climbed on wire, it can be hammered into thin sheets, it aligns with many other metals, it can be cast and molded into very detailed shapes, it has a wonderful color and a brilliant shine. Gold is a memorable metal that occupies a special place in the human mind. Gold is highly prized not only for its natural beauty but also for its rarity, utility and versatility, and can be found in almost every area of modern life.
The numerous and diverse properties of gold, some of which are unique to gold, make it an indispensable and vital component in several fields. Traditionally, gold has been used to make coins, ingots and jewelry, but in recent times it has been used in a variety of less typical ways. Gold has a very low shear resistance and a thin film of gold between critical moving parts serves as a lubricant: gold molecules slide over each other under the forces of friction and provides a lubricating action. Gold is also used in infrared shielding, the production of colored glass, the coating of gold leaves and the restoration of teeth.
Banknotes (which become gold coins) and gold certificates (convertible into gold coins at the issuing bank) were added to the circulating stocks of standard currency in most industrial economies of the 19th century. For example, gold electrical cables were used during some of the Manhattan Project's atomic experiments, but the project's calutron isotope separator magnets used large, high-current silver cables in calutron isotope separator magnets. However, they had one thing in common: they both appreciated gold and used it to make some of their most important objects. In the same way, gold is associated with perfect or divine principles, as in the case of the golden ratio and the golden rule.
European exploration of the Americas was largely driven by reports of gold ornaments displayed in large numbers by Native American peoples, especially in Mesoamerica, Peru, Ecuador and Colombia. After initial production, gold is often industrially refined using the Wohlwill process, which is based on electrolysis, or through the Miller process, that is, chlorination in the molten mass. The use of gold crowns on the most prominent teeth, such as incisors, is preferred in some cultures and discouraged in others. Gold is also used in medicine in the form of salt or radioisotopes taken orally or by injection to relieve certain conditions, such as severe rheumatoid arthritis and tuberculosis.
World governments have abandoned gold standards and the direct convertibility of currencies into gold, and in 1971 the United States refused to exchange its dollars for gold. As a highly prized precious metal, gold looks natural on religious crowns, awards and statues. Some gold salts have anti-inflammatory properties, and currently, two are still used as pharmaceuticals in the treatment of arthritis and other similar conditions in the U.S. UU.
(sodium aurothiomalate and auranophine). For example, gold is used in the connectors of the most expensive electronic cables, such as audio, video and USB cables. Several people have claimed that they can economically recover gold from seawater, but they made a mistake or acted intentionally. Central banks continue to hold part of their liquid reserves in the form of gold in some form of gold, and metal exchanges, such as the London Bullion Market Association, continue to settle gold-denominated transactions, including future delivery contracts.
