Deep sea mining is a process to retrieve minerals from the ocean floor at a thousand or more of the surface. Deep sea mining is constituted the largest and least understood biological habitat on Earth and has become an environmental risk with the impacts of deep sea mining have been enormous and unavoidable because of the seabed habitat degradation around vast ocean areas, species extinctions

Deep sea mining

Deep sea mining is a mineral retrieval process that takes place on the ocean floor.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

What is Deep
