Gold comes from the Latin word Aurum and still owes its abbreviation AU to it. Common countries where gold is found are South Africa, Canada, Russia, China, Australia and the United States. Gold is also found in Europe. Just think of Switzerland. Gold is used less for Industry because of the high price of gold. Main operation is for jewelry making. But gold leaf is even used for some dishes. Gold is often mined unbound in the form of chips to clogs of up to 60 kilos. The major disadvantage of mining gold is the release of a lot of waste, which is bad for the environment.
Origin of gold.
Billions of years ago there were meteorites that poured into the earth en masse. These meteorites had absorbed various substances into the Universe and actually brought them back to Earth. One of these substances was gold. These substances largely sank to the core of the earth. However, some remained in the atmosphere and was absorbed into water. Earthquakes created an effect of very fast evaporation of water in the earth's crust. The water evaporated very quickly but the dissolved substances in the water. including gold was left in this place. Gold veins were created by repeating this process. This is called flash evaporation. This process of creating a gold vein sometimes took up to 100,000 years.
Gold jewelry .
Gold is widely used for jewelry making. Because it does not rust, has a low melting limit and flexibility. So flexible, in fact, that copper or silver is added to the jewelry to harden the metal. This is also stated on jewelry. In the Netherlands, gold jewelery is almost always 15 carat (585/1000). But 18 carat (750/1000) and 8 carat (333/1000) also occur. Due to the high price of gold, recycling of this precious metal is of paramount importance. About 25 percent of the new supply comes from this. The content of gold jewelry is tested with Koningswater
Gold as an investment.
Since time immemorial, gold has been used not only as jewelry but also as an investment. Just think of countries such as Turkey where this still occurs. The purchase and sale for the population is still per gram. Of course there is a trade margin for the trader. In the Netherlands we do not know this and a piece of jewelry is really just a piece of jewelry. Gold has also been used as a currency since time immemorial and thus as a means of payment. This was true for every country. In the Netherlands this was abolished after the lifting of the gold standard. An example of this are the last golden decades from the 1930s. However, gold commemorative coins are still made with a theme. Until today gold coins are still minted in a number of countries with the aim of gold investment. These coins are often made of pure gold. Just think of countries such as the United States (Golden Eagle), Canada (Maple Leaf), Mexico (Lbertad) and Africa (Krugerrand) etc. etc. Gold bars are also very popular with investors and are issued by various countries.
Gold in sewer.
A place where one would not expect gold. Yet there is gold in the sewer because the processing of products creates waste that ends up in the sewer. However, these concentrations are very small and recycling of this gold is therefore not profitable. However, a nice example of where it is profitable: In the Jura region in Switzerland. There are so many gold-processing companies in this area that the total annual amount in the Swiss sewer brings to 300 kilos of silver and 43 kilos of gold. Which is currently 30 million euros.
Switzerland and gold refineries.
In the top three of the world gold refinery. (Arger Heraeus). Switzerland's production of gold bars accounts for about 40 percent of all new bars supplied. New hijackers for this trade are also on the coast. The world's largest refinery is being built in Dubai to take over parts of Asian countries.
