Deep-sea mining equipment

Definition

Deep-sea mining equipment refers to specialized tools and machines designed for extracting minerals and resources from the ocean floor at depths typically beyond 200 meters. This equipment is crucial for accessing valuable resources like polymetallic nodules, hydrothermal vents, and seafloor massive sulfides, which can contain precious metals and rare earth elements. As the demand for marine minerals grows, advancements in technology are making deep-sea mining more feasible and efficient, while also raising concerns about environmental impacts and sustainability.
