Gold from ocean? Extraction from seawater

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 factor
