Deep sea mining - Wikipedia
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,An alternative: Deep-sea tailings,- Australian Mining,Deep-sea mine tailings placement (DSTP) is an alternative to land-based mine-waste disposal, whereby mineral ore is converted into slurry and transported via a pipeline to processing plants,Understanding the impact of deep-sea mining | MIT News,,In deep-sea mining, a collector vehicle would be deployed from a ship. The collector vehicle then travels 15,000 feet down to the seabed, where it vacuums up the top four inches of the seabed. This process creates a plume known as a collector plume.
