Deep sea mining - Wikipedia

  

2019-10-14  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.[1] The vents create globular or massive sulfide deposits, which contain
