Deep sea mining - WikipediaDeep sea mining is a relatively new 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.Sand Mining Database | Coastal CareCoast of the United States, Government, Minerals Management Service, INTERMar.
