The treasure is hidden in the oceans of the world. According to scientists, about 200 million tonnes of gold is dissolved in sea water. One gram of gold is found in every 10 million metric tons of seawater. Because of this, the amount of gold is very subtle, but when it is seen globally, its value is judged in trillion dollars. According to estimates, the price of gold present in the sea can be around $ 2000 billion, but the question is, if so much gold, why can’t we remove it?
Gold in the oceans is presented due to natural causes. Rains and rivers rub the rocks and the gold present in them reaches the sea. On sea level, hydrothermal vents release minerals and warm water, which dissolves in water. Sea volcanic activities also contribute to it. This process has been going on for thousands of years.
Efforts to remove gold
Scientists have many times used to extract gold from the sea. An electric-regional method was suggested in 1941, but its cost gold price It was many times more than. In 2018, a new technology was described in which a particular substance absorbs gold, but it is not possible to apply it on a large scale.
Technical and economic challenges
One liter of seawater is only less than 1 nanogram. It is very difficult and expensive to separate such a subtle amount from billions of liters of water. This is the reason that this mining is not beneficial in today’s situation.
Will it be possible to remove gold from the sea in future?
Despite the development of technology, extracting gold from sea water is not economically practical. If there are revolutionary changes in nano-technology and chemical engineering in future, then this process can be easier. Then this mining will have a profound impact on the global supply and pricing of gold, but right now it is only a matter of scientific imagination and research.
