Exstacring Resoruces From The Sea Floor

Precipitating minerals also form seafloor chimneys and mineral particles in the fluids venting at the seafloor make the fluids look like smoke.

Exstacring resoruces from the sea floor.

Ocean mining not a gold rush but an option for decades people have been extracting mineral resources from the sea including diamonds off namibia or sand from the coastal areas of europe for filling depleted beaches. Uk seabed resources a wholly owned subsidiary of lockheed martin uk in partnership with the department for business energy and industrial strategy holds licences and contracts to explore a total of 119 000km2 of the pacific sea floor for mineral rich polymetallic nodules. Resources presently extracted from the sea or areas that were formerly in the sea range from common construction materials to high tech metals to water itself. What causes the water in the ocean to move.

Uncertainty also surrounds the processing of the mined ores and the number of metals that can be economically recovered. How can moving wind or water produce electricity. The most obvious of these is salt mining. Offshore platforms are a relatively new way of extracting minerals from the ocean floor.

Certain other methods have been around for ages. Minerals and related depths diamonds are also mined from the seabed by de beers and others. Oil and natural gas are the most valuable non living resources taken from the ocean. Seafloor mining hot buoyant mineral laden fluids rise from deep within ocean crust and mix with cold seawater.

That triggers the precipitation of minerals that form deposits near and on the seafloor. Oil platforms have dozens of oil wells that are drilled in places where the ocean is sometimes 2 000 m deep. Gas hydrates can be mined from the ocean then methane can be extracted from them for energy. Extracting these resources requires drilling into the seafloor.

Extracting these resources requires drilling into the seafloor. Oil platforms have dozens of oil wells that are drilled in places where the ocean is sometimes 2 000 m deep figure below. Resources oil and natural gas are the most valuable non living resources taken from the ocean. Chemical analyses have demonstrated that sea water contains about 3 5 percent dissolved solids with more than sixty chemical elements identified.

The deep sea contains many different resources available for extraction including silver gold copper manganese cobalt and zinc.
