PostSubject: Can Gold be Extracted from Seawater?   Wed Sep 25, 2013 11:49 am

Hello,

Yes, it is possible to extract gold from seawater in theory, but it's really not practical to do so. It is estimated that there is, in total, about eight million tons of gold dissolved in the world’s oceans. While this is a lot, the oceans are huge, and the actual concentration of gold in seawater is only about . To put it another way, there is depending on location, making it uneconomical to extract using any current technology.

The Sea as a Source of Minerals: Since the sea is fed by rivers that flow over land containing metals, minerals and ores, a great variety of these can be found in seawater in the form of soluble compounds. This is added to by material from hydrothermal vents — fractures in geologically active areas of the ocean floor through which hot, mineral-rich water flows into the ocean. The concentration of different elements in the oceans depends not only on their abundance in the Earth’s rocks, but in their reactivity and solubility.
