Bacterial Contributions to the Formation of Polymetallic Nodules in the Pacific Ocean
Frontiers in Marine SciencePolymetallic nodules, widely distributed in the deep seafloor of the Pacific Ocean, are characterized by their abundance of diverse metal elements and considerable economic value. Previous studies have suggested a partial biogenic origin of these nodules.

Restoration experiments in polymetallic nodule areas. [PDF]
Integr Environ Assess Manag, 2022 Abstract Deep-seabed polymetallic nodule mining can have multiple adverse effects on benthic communities, such as permanent loss of habitat by removal of nodules and habitat modification of sediments. One tool to manage biodiversity risks is the mitigation hierarchy, including avoidance, minimization of impacts, rehabilitation and/or ...

Frontiers in Marine ScienceMost studies on the genesis of polymetallic nodules suggested that nodules in the South China Sea (SCS) are hydrogenetic; however, the complexity and the heterogeneity in hydrology and geochemistry of the SCS might cause different processes of nodule ...

Comminution of Polymetallic Nodules with a High-Pressure Water Jet. [PDF]
Materials (Basel), 2022 This paper presents an original method for the comminution of polymetallic nodules in a hydro-jet mill of our own design, having the water jet pressure in the range of 70–200 MPa. The best comminution results are ensured by equipping the mill with a water jet having a diameter dw = 0.7 mm and a comminution-homogenization tube having a diameter dh = 2.4

Review and Integrated Framework for Deep-Sea Mineral Resources, Ecological Influence, and Future Development. [PDF]
Int J MicrobiolAs global industrialization advances and land‐based resources decline, deep‐sea resource development is becoming increasingly vital. The deep sea is rich in minerals such as polymetallic nodules, polymetallic sulfides, and cobalt‐rich crust. However, deep‐sea ecosystems and geochemical cycles can be severely impacted by extensive mineral mining.

Dynamic Traction of Deep-Sea Polymetallic Nodule Collector
Journal of Marine Science and Engineering, 2023 The ocean is extremely rich in mineral resources. To cope with the shortage of land mineral resources, countries are focusing on the development of deep-sea mineral mining technology.

Ecology of a polymetallic nodule occurrence gradient: Implications for deep-sea mining. [PDF]
Limnol Oceanogr, 2019 AbstractAbyssal polymetallic nodule fields constitute an unusual deep‐sea habitat. The mix of soft sediment and the hard substratum provided by nodules increases the complexity of these environments. Hard substrata typically support a very distinct fauna to that of seabed sediments, and its presence can play a major role in the structuring of benthic ...

Scientific Reports, 2021 Polymetallic nodule fields provide hard substrate for sessile organisms on the abyssal seafloor between 3000 and 6000 m water depth. Deep-seabed mining targets these mineral-rich nodules and will likely modify the consumer-resource (trophic) and ...
