· Dissolve gold existed as gold chloride in seawater, but in a very small amount. So, the gold separation should be focused, in order to make this process to be a successful one. Factors such as depth, climate, region, temperature need to be considered.
Gold extraction refers to the processes required to extract gold from its ores.This may require a combination of comminution, mineral processing, hydrometallurgical, and pyrometallurgical processes to be performed on the ore.. Gold mining from alluvium ores was once achieved by techniques associated with placer mining such as simple gold panning and sluicing, resulting in direct recovery of ...
· Extraction of uranium from seawater would be useful if the issue with nuclear power was a lack of uranium. The problem is though - there is no shortage of uranium. ... Maybe the Gold …
· One last thing about extracting gold from seawater. The amount of gold per volume of seawater is so low that you need a huge part of energy to extract a tiny bit of gold. This energy is far more worth than the gold you extract. Even when you produced the energy by solar cells, you would be far beter of selling your energy.
Fritz Haber, a German chemist, proposed extracting gold from seawater as a way to pay off Germany''s debt, $ 28.8 × 10 6, after World War I. The value of gold at the time was $ 21.25 / troy oz ( 1 troy o z = 31.103 g). The gold concentration in seawater is 0.15 m g gold/ton seawater ( 1 ton = 2000 l b ).
· Hello, there are millions of tonnes of gold in oceans, but so scattered that it is practically impossible to extract even small quantities to hold in your hands. It is possible, however, millions of gallons of seawater must be processed in order to get some gold.

· The main and currently most efficient method of extracting gold from seawater is Electrolysis, as the Positively charged gold atoms are attracted to the negative charge outlet, meaning it is perfectly possible to extract gold, but it costs so much energy to preform this process, and on top of that the water has to be processed so you don''t end ...
· The best idea I am considering is to extract gold and other precious metals from this existing seawater flow. Many people said that gold extraction is uneconomical because of the amount of sea water one has to pump to shore. The energy involved in pumping so much seawater …
Gold-mining activities have been an issue, especially when it involves in contamination of chemicals, for example arsenic and mercury. However, despite of these hazards, gold-mining activities are still being conducted. This is because the gold is worth, regardless of the problems. Gold-mining, as known needs a very large area of land, or site plant. Vast amount of labor force, mechanical ...
· The ocean, however, is deep, meaning that gold deposits are a mile or two underwater. And once you reach the ocean floor, you''ll find that gold deposits are also encased in rock that must be mined through. Not easy. Currently, there is no a cost-effective way to mine or extract gold from the ocean to make a profit.
He and his boyhood friend, Fisher, founded the Electrolytic Marine Salts Company, an endeavor that promised to extract millions of dollars in gold from the seawater racing through the Mill Creek site. At the time, many wondered why remote North Lubec was chosen for such an undertaking.
· For Haber, it was just a matter of extracting the gold to create a whole new source of wealth for Germany—one that would continue on well past the time their debt was paid.
