Degradation of Polymetallic Nodules in Deep-Sea Multi-Stage Lifting Motor Pump [PDF]

Minerals (Basel, Switzerland), 2021
The polymetallic nodules in the deep-sea multi-stage lifting motor pump will undergo repeated impeller blade impact and fragmentation, which will change the particle size, thereby affecting the number of ores that can be recovered on the surface and the design parameters of the processing equipment.

Environmental predictors of deep-sea polymetallic nodule occurrence in the global ocean

Geology, 2020
Abstract Polymetallic nodules found on the abyssal plains of the oceans represent one of the slowest known geological processes, and are a source of critical and rare metals for frontier technologies. A quantitative assessment of their occurrence worldwide has been hampered by a research focus on the northeastern Pacific Ocean and the ...

Deep-sea Polymetallic Nodule Mining: Challenges Ahead for Technologists and Environmentalists

Marine Georesources & Geotechnology, 2003
Although, offshore mining for mineral wealth is not required at present, it may be the only alternative in the future due to the continuous growing demand for certain metals that have no or limited land deposits. Risk involved in deep-sea mining is not less than that in space missions. Limited groups of mining engineers and environmental scientists are
