- Remediation technologies for deep-sea mining tailings were mainly evaluated in
this research in order to derive candidate technologies for the future development of practical
remediation technologies required for commercial deep-sea mining to respond to
strengthening of international marine environmental standards. Polymetallic nodules which
were collected at the Clarion-Clipper zone in the Pacific Ocean consist of mostly inorganic
materials such as manganese (Mn, 61.0%), silicate (Si 10.3%), iron (Fe, 5.57%), heavy metals
and other tiny elements. It is assumed that deep-sea mining tailings may be slurry mixed with
fine solid materials having a particle diameter of several tens to 100 μm which are originated
from crushing of polymetallic nodules and liquid substance produced from selection process
on vessel connected with lifting and collecting procedures. Fine particles as well as harmful
components eluting from deep-sea mining tailings may adversely affect marine environment
including marine life. A new modular remediation treatment system in which physical
separation and chemical treatment are repeated several times in a single treatment flow
should have to develop in order to overcome various limitations (space, energy, process water,
vibration, corrosion, weather conditions, etc.) at sea area.
