Gold mining in Alaska, a state of the United States, has been a major industry and impetus for exploration and settlement since a few years after the United States acquired the territory from Russia. Russian explorers discovered placer gold in the Kenai River in 1848, but no gold was produced. Gold mining started in 1870 from placers southeast of Juneau, Alaska.
A new frontier for diamond mining: The ocean Companies also plan to begin mining offshore for gold in coming years, with one commercial operation scheduled to launch in 2018 off Papua New
The 1st big underoceanminer was in 2009 at 31deg 18′ N by 23deg 14′ W over 3 miles deep. The trenches were over 500′ wide spaced 10 miles apart over a 100 mile by 100 mile grid.
Mining the ocean floor of the central Pacific on a commercial scale is five years away, but the beginnings of an underwater gold rush are under way The number of companies seeking to mine beneath
· Why the is missing out on the race to mine trillions of dollars worth of metals from the ocean floor. Rare earth elements and metals used in cell phones, supercomputers and more are sitting
· Each mining ship has a team of 120, with 60 people working on board for each 28day rotation. Employees are flown by helicopter to and from the vessel.
Deep sea mining is a mineral retrieval process that takes place on the ocean mining sites are usually around large areas of polymetallic nodules or active and extinct hydrothermal vents at 1,400 to 3,700 metres (4,600 to 12,100 ft) below the ocean''s surface. The vents create globular or massive sulfide deposits, which contain valuable metals such as silver, gold, copper

There''s gold in the ocean! Ikhwan Zailani yuslim/CC BY The oceans are filled with gold, just floating out there for the taking! The trouble is figuring out how to extract the precious metal.
Regardless, the deepsea gold rush is on: An analysis from the Massachusetts Institute of Technology predicts deepsea mining will be widespread by 2040. Learn more. Wealth in the Oceans: Deep sea mining on the horizon? (via the United Nations Environment Programme) Read more about the mining process and the environmental risks.
Mining executives insist that their work in the ocean is misunderstood. Some adopt a swaggering bravado and portray the industry as a romantic frontier adventure. As the manager of exploration at
The discovery of a gold deposit lying 2000 meters undersea provides the need for new drilling technology for future gold mining," Zhang said. The marine prospecting took three years, and involved over 120 kilometers of drilling, with 67 sea drilling platforms and about 1,000 drillers and geologists.
Deep Sea mining, like asteroid mining, is a relatively unconventional method of extracting Rare Earth elements (REEs). Unlike asteroid mining, however, deep sea mining has already been undertaken through projects such as deep sea diamond mining. Actual mining for REEs has not been attempted because of environmental issues and cost. These issues are much more complicated and not as
These Fearsome Robots Will Bring Mining to the Deep Ocean One of the three robots Nautilus minerals will use for mining. The collecting machine sucks up the resulting sand/gravel/silt and pumps it
Blue Mining: breakthrough solutions for sustainable deep sea mining. An international European consortium of 19 large industry and research organisations on various maritime fields of expertise, the "Blue Mining" consortium, will develop solutions that will bring sustainable deep sea mining a big step closer. In a duration of 48 months the "Blue Mining" project will address all aspects
· 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.
Deep sea mining threatens unique marine life, experts warn Mon, 26 Jun 2017 Gland, Switzerland, 26 June 2017 (IUCN) – Mining the deep ocean floor would inevitably lead to the loss of biodiversity, which cannot be compensated for through biodiversity offsets, 15 marine scientists and legal scholars argue in a letter published today in the journal Nature Geoscience.
