  • Can Gold be Extracted from Seawater? (with pictures)

    2020-7-8  Extraction. Due to the extreme dilution of gold in seawater, there is currently no economically viable method of obtaining the metal from this source. Vast amounts of seawater would have to be evaporated to concentrate it sufficiently to allow it to be recovered by any conventional process. This in itself would require a lot of energy, with ...

    Gold processing Britannica. The mining of alluvial deposits and, later, lode or vein deposits required crushing prior to gold extraction, and this consumed immense amounts of manpower. By ad 100, up to 40,000 slaves were employed in gold mining in Spain. The advent of Christianity somewhat tempered the demand for gold until about the 10th century.

  • OSA Sample Handling of Gold at Low Concentration

    Since the early 1900s, investigators have attempted to measure the gold content of seawater. After devoting ten years to quantifying its concentration, Haber concluded that insufficient gold existed in seawater (20 pg g−1-20 ng g−1) to merit its economic extraction. Subsequently, gold has been determined in seawater, often with values ranging from those reported by Haber to those orders of ...
