Abstract

Deep-sea mining extracts polymetallic sulphides at extreme depths, requiring sustainable approaches to minimize environmental impact. Seabed milling, particle transport, and a hydrocyclone based containment system are modelled in CFD-DEM simulations to support the development of efficient and sustainable deep-sea mining operations. For instance, turbulent material transport can be enhanced with shielded counter-rotating trench cutter wheels while mitigating turbidity plumes. Furthermore, with parametric studies on hydrocyclone pressure drop and separation efficiency, we designed the separator unit.
