The gold is separated from the solution by either running it over zinc shavings or by means of electrolysis. In either case the gold is deposited as a black mud and is periodically collected and refined. In electrolysis the solution flows continuously through vats containing either lead or tin plate cathodes and oxidized lead anodes.
Researchers Fishing Pure Gold from Seawater – ScienceNewsHub. May 16, 2016· GERMANY – The sea is a gold mine depending on where you look. Normally one liter of sea water contains only a few billionths of a gram of gold. But now researchers have discovered from a bubbling spring on the Icelandic Reykjanes Peninsula.
Electrolysis of water is the decomposition of water into oxygen and hydrogen gas due to the passage of an electric current.. This technique can be used to make hydrogen gas, a main component of hydrogen fuel, and breathable oxygen gas, or can mix the two into oxyhydrogen, which is also usable as fuel, though more volatile and dangerous.. It is also called water splitting.
Sea water contains about mg/tonne of gold dissolved in water (average 1 mg/tonne). But considering the amount of seawater available, it is a really huge goldmine! Theoretically fine, but problems were practical (which prevented profitable ex...

In implementation of the hydrogen economy, the electrolysis of sea water as the source of hydrogen has been discussed. Two options exist for performance of this electrolysis. The first option is to subject the water to total desalinization to remove all impurities and produce essentially distilled water.
