The gold deposits grown at a total eligible cost will be exhausted in 2025:
Gold is a chemical element symbol of Au and atomic number 79.
This precious metal is the sixth non-renewable resource supply to disappear because of intensive human exploitation, together with the zinc and indium .
The gold comes from the exploding star whose remains have given birth to the Sun and Earth, there are more than five billion years.
The stock is estimated at 42,000 tons in mineable. June
2008: he is 17 years of reserves at current production rate which is 2 500 tonnes per year.
depletion of gold will be final in 2025. At the same time as zinc and indium.
sources come primarily from the USGS (the United States Geological Service) http://minerals.usgs.gov/
This date is provided for informational purposes only. It may indeed vary according to the sources and evolution of our civilization.
86% of production is used in jewelry and jewelry. But gold is used in electronics, dental, coins and medals.
The problems caused by the disappearance gold will occur well before the deadline.
course, gold will still be present in the basement, but as a highly diluted and therefore unusable. We still find in the alluvium of the rivers form of flakes, but in very small quantities.
The Moon and the asteroids do not contain a usable form. And you realize the energy expenditure it would take to bring back from Mars or Venus! It will
recycling, but supply will certainly be less than demand, which will only continue to grow with the exponential growth of emerging countries.
Known reserves are very scattered throughout the world. 34% are located in South Africa, Australia and Peru.
Although, thanks to advanced technologies, we discovered new deposits during further exploration of the crust, it would only extend the deadline a few years and would not change much in the game.
For the record, Russian scientists have managed to turn a few micrograms of gold from lead in a nuclear reactor, but at an astronomical cost. Similarly, it is possible to produce minute quantities in particle accelerators, but with immense energy expenditure.
