Gold, beauty and power have always been associated. The kings have moved their empires in search of gold, and countless battles have been fought by this precious metal. The saying goes “Gold is where you find it”, and in this case it’s found in nature.
It’s estimated that there are 216,600 tonnes of gold on the planet. Of which, only a little more than 23% remain below the surface of the earth. And the rest, have already been extracted. Its main uses are jewelery (51% of the total), as an investment product (18% of the total), storage in central banks as a guarantee of state money (17% of the total), and for technological uses (12% of the total).
Above is an infographic that also tells us where the main gold mines are. Currently 2,500 tonnes of gold are extracted annually (about 1% of the total on the planet). The high price of gold at the moment, is making the extraction is more intense.
By region, the main producer is Asia. Followed by Africa, South America, North America, Oceania and lastly Europe. By country, the most fruitful are Australia, South Africa, Russia, Indonesia, Chile and the United States. There’s also an important recycling induction. Thus, almost 40% of “new gold” comes from recycling.
The word gold comes from the Latin “aurum”, so its symbol in the periodic table is the Au. And further recounting Wikipedia, we see the most established hypothesis about its creation: “Gold is created thanks to the extreme conditions in the collapsing nucleus of supernovae”.
There are other theories. In addition to many legends about gold, one of them is related to the Sumerian culture, in which it’s said that the Anunakis created the human race to extract the gold, since in their planet of origin they needed it to recover the atmosphere of their home planet. However, this theory doesn’t explain the incessant increase of the price of the gold in the last decades.
Gold is generally found in its pure state. In nature it can be extracted from some rivers, because the water that descends from the mountains erodes the channels and drags small pieces of gold that often do not reach even a gram.
Another theory tells us that because faults in the earth’s crust raise gases and liquids that give rise to the formation of gold, this theory is disputed by scientists who assert that the temperatures and pressures reached by the Earth’s core are not sufficient enough to cause the nuclear fusion necessary for the formation of gold.
It’s very well known that the most popular use of gold occurs in the world of jewelry.
Pure gold, which is 24 karat and contains 999 thousandths (99%) of gold is not used that much in jewelry due to its malleability, because it’s very easy to deform. To avoid this problem, the most commonly used is an 18-carat 750-thousandths (75%) gold, commonly known as 18-carat gold, and is much more common because of its greater hardness.
In fact, 18 karat gold is pure gold with silver, copper or both, depending on the tonality you want to have.
We’ve all heard of white, yellow and pink gold. These types of gold are actually based on yellow gold to which you add another metal in its alloy to give it the desired color and hardness. For example: White gold: it consists of 75% gold, 16% palladium and 9% silver, while pink gold: contains 75% gold, 5% silver and 20% copper.
Nowadays, we have seen that gold of other colors are trend like blue, green or red gold. They are just simply gold with other alloys of different metals and proportions of them.
