CFD-DEM analysis of internal flow characteristics in multistage deep-sea mining pumps

Ships and Offshore Structures
The potential profits associated with deep-sea mineral deposits have encouraged the development of new mining techniques. In particular, the effectiveness of lift pumps is crucial to the success or failure of these mining operations.

Precautionary management of deep-sea mining

Marine Policy, 2002
Abstract Interest in deep-sea mining developed in the early 1970s, with a focus on manganese nodules in international waters. Mining may actually occur first, however, on rich polymetallic sulfide deposits associated with hydrothermal vents within exclusive economic zones.

Deep-sea mining as an emerging threat to deep sea ecosystems

The deep sea is the biggest ecosystem on Earth, representing around 90% of the marine environment. Despite its remoteness and inaccessibility, the deep sea is under constant threat from anthropogenic activities. Among them is deep-sea mining, that is quickly rising as an appealing alternative to land-based mining.

Deep-Sea Mining, Why Not?

The world appears to be on the verge of commercial deep-sea mining for polymetallic nodules in the Clayton-Clipperton Zone in the Pacific Ocean. Access to critical materials, needed for the energy transition to combat climate change, is the main argument presented to start this mining.This paper philosophically reviews the prospect of deep-sea mining ...
