Deep-sea mining | IUCN

• Deep-sea mining is the process of retrieving mineral deposits from the deep sea – the area of the ocean below 200 m. • Depleting terrestrial deposits and rising demand for metals are stimulating interest in the deep sea, with commercial mining imminent. • The scraping of the sea floor and pollution from mining processes can wipe out entire species – many yet to be discovered.Understanding the impact of deep-sea mining | MIT News,,Dec 05, 2019· 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.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, manganese, cobalt, and zinc. The deposits are mined using either hydraulic pumps or bucket systems that take ore to the surface to be pr…
