Extracting Gold from Seawater - Gold Refining Forum.com

03/11/2014· 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 would make it uneconomical. But what if, the pumping cost is zero, I am already pumping for my hydroturbine using renewable energy, I can deliver this amount of seawater flow for free. All of a sudden, the energy …

How to Extract Gold From Seawater - EzineArticles

Gold from seawater? Yes, it is possible and there is plenty there. With gold prices over $1000 an ounce, then the pressure is on to develop economical methods of extraction. There are bacteria which are used in gold ore refining, and bacteria which can possibly extract it from seawater, where gold concentrations are higher in parts of the deep ocean.

Gold from ocean? Extraction from seawater

28/01/2008· In the early 1920's Haber spent a lot of time working on an extraction process to remove gold from seawater, and surveying the oceans for dissolved gold. He hoped that the gold could be used to help pay off Germany's enormous reparations payments from the war. Ultimately, he found that there was nowhere near enough gold in seawater to make extraction economically feasible (by about a …

When Germany Tried To Turn Seawater Into Gold - KnowledgeNuts

16/07/2014· Fritz Haber was one of Germany's great scientific minds during World War I. He had already made invaluable contributions to the war effort, so when Germany was facing an overwhelming debt and had no gold to speak of, they turned to their prodigal son. Haber delivered by creating a complicated electrochemical process that he thought would extract gold from seawater. Before the process could ...
