Attempts to extract gold from seawater were common in the early 20th century. A number of people claimed to be able to economically recover gold from seawater, but they were all either mistaken or acted in an intentional deception. Prescott Jernegan ran a gold-from-seawater swindle in the United States in the 1890s.
In June 2021, the Republic of Nauru partnered with The Metals Company to extract deep-sea minerals, driven by the need for renewable energy to support its energy sector. [125] While deep sea mining could provide vital resources, its extraction requires significant energy and capital, and may cause environmental and social impacts on the island.
The lease covered an area of 59 square kilometres to a depth of 1,600 meters in the Bismarck Sea to extract essential resources for a period of 20 years. Nautilus sought to extract a total of 1.3 tons of materials, including 80,000 tons of high-grade copper and 150,000 to 200,000 ounces of gold sulphide ore over the course of 3 years. [ 7 ]
Gold occurs principally as a native metal, i.e., gold itself.Sometimes it is alloyed to a greater or lesser extent with silver, which is called electrum.Native gold can occur as sizeable nuggets, as fine grains or flakes in alluvial deposits, or as grains or microscopic particles (known as colour) embedded in rock minerals.
In 1970, South Africa produced 995 tonnes or 32 million ounces of gold, two-thirds of the world's production of 47.5 million ounces. [2] Production figures are for primary mine production. In the US, for example, for the year 2011, secondary sources (new and old scrap) exceeded primary production. [3]
Experiments show that the new technology can extract lithium from wastewater from oil production and potentially from seawater, a process that is not commercially viable today.

World gold production was 3,612 tonnes in 2022. [36] As of 2020, the world's largest gold producer was China with 368.3 tonnes of gold mined in that year. The second-largest producer of gold was Russia where 331.1 tonnes was mined in the same year, followed by Australia with 327.8 tonnes. [37]
