Complete mitochondrial genome of the abyssal coral Abyssoprimnoa gemina Cairns, 2015 (Octocorallia, Primnoidae) from the Clarion-Clipperton Zone, Pacific Ocean [PDF]

ZooKeys, 2023
The Clarion-Clipperton Zone (CCZ) in the tropical East Pacific is a region of interest for deep-sea mining due to its underwater deposits of polymetallic nodules containing economically important metals such as nickel, copper, and cobalt.

Review and Integrated Framework for Deep‐Sea Mineral Resources, Ecological Influence, and Future Development [PDF]

International Journal of Microbiology, Volume 2026, Issue 1, 2026.
As 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.

Potential impacts of polymetallic nodule removal on deep-sea meiofauna [PDF]

Scientific Reports, 2021
Deep seabed mining is potentially imminent in the Clarion Clipperton Fracture Zone (CCFZ; northeast Pacific). Seabed collectors will remove polymetallic nodules and the surrounding surface sediments, both inhabited by meiofauna, along their path.

Air-Lift Pumping System for Hybrid Mining of Rare-Earth Elements-Rich Mud and Polymetallic Nodules around Minamitorishima Island

Journal of Marine Science and Engineering
REE-rich mud under the seabed at a 5500–5700 m water depth around Minamitorishima island and polymetallic nodules buried in the deep seabed are very promising and attractive to explore and develop.

Different Ferromanganese Concretion Morphologies Host Distinct Microbial Communities and Metal Accumulation Patterns in the Baltic Sea [PDF]

Environmental Microbiology, Volume 28, Issue 7, July 2026.
We investigated how microbes influence the metal accumulation and release in Fe‐Mn concretions from the Gulf of Finland using microcosm incubation experiments. We studied three main concretion morphotypes: crust, discoidal, and spheroidal. Microbes enhanced metal accumulation in discoidal and spheroidal morphotypes.

Electrowinning of nickel in the processing of polymetallic sea nodules

Hydrometallurgy, 1990
Abstract As the land based reserves for nickel in India are meagre its extraction from sea nodules will assume increasing importance in the coming years. In the processing of polymetallic sea nodules by the reduction roast/ammonia leach/solvent extraction route, the recovery of nickel by electrolysis was considered.

Restoration experiments in polymetallic nodule areas [PDF]

Integrated Environmental Assessment and Management, 2021
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 ...
