Aug 07, 2017· While electrolysis is an established process it will not work at the low levels of gold in the sea water. Separation of gold from sea water by any means will prove more expensive than the value of the metal recovered. This is the same dilemma as with alternate energy options. rishi
Jun 25, 2018· Ocean waters do hold gold, but it''s difficult to say exactly how much. If you were hoping make your fortune mining the sea, consider this: Gold in the ocean is so dilute that its concentration is very small. One study found there is only about one gram of gold for every 100 million metric tons of ocean water in the Atlantic and north Pacific.

Copper processing is a complicated process that begins with mining of the ore (less than 1% copper) and ends with sheets of % pure copper called cathodes, which will ultimately be made into products for everyday most common types of ore, copper oxide and copper sulfide, undergo two different processes, hydrometallurgy and pyrometallurgy, respectively, due to the different ...
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...
The Moebius Process of Purification of Gold by Electrolysis is now in successful operation and is said to be specially suitable for refining copper bullion containing large proportions of silver and gold with small quantities of lead, platinum, and other metals, but is chiefly used in parting dore silver containing not more than 20 per 1,000 of base metals.
The Miller process uses gaseous chlorine to extract impurities when gold is at melting point; impurities separate into a layer on the surface of the molten purified gold. The Miller process is rapid and simple, but it produces gold of only about percent purity. The Wohlwill process increases purity to about percent by electrolysis.
