Thermal Pre-Treatment of Polymetallic Nodules to Create Metal (Ni, Cu, Co)-Rich Individual Particles for Further Processing

, 2018
Polymetallic nodules are a potential source of industrially demanded metals such as Ni, Co, Cu, and Mo (up to 3 wt %). Even if there is no deep-sea mining of manganese nodules today, a forecasted gap between metal demand and supply as well as ...

Analytical studies of sea bed polymetallic nodules by atomic absorption spectrophotometry

, 1985
An analytical scheme using Atomic Absorption spectrophotometry has been proposed for analysing Fe, Ni, Cu, Co in polymetallic seabed nodules. More sensitive lines were taken in case of Ni, Cu and Co whereas less sensitive lines were used for Fe and Mn ...

The influence of habitat heterogeneity and disturbance on benthic community structure in deep-sea polymetallic nodule environments and management implications for seabed mining

Frontiers in Marine Science
Habitat heterogeneity is known to influence faunal community structure, but its influence on deep-sea benthic communities remains understudied, particularly for polymetallic nodule environments in abyssal waters.

Bioprocessing of polymetallic Indian Ocean nodules lusing a marine isolate

, 2004
Polymetallic Indian Ocean nodules offer a lucrative resource for valuable strategic metals like Cu, Co and Ni. A novel bioleaching process to recover those metals from the nodules at near-neutral pH and ambient temperature is presented in this paper. The

Kinetics of oxidative leaching of ocean polymetallic nodules in molten potassium hydroxide medium

, 2005
The kinetics of oxidative leaching of ocean polymetallic nodules in molten potassium hydroxide medium was investigated in terms of the gas-flow rate, stirring rate, reaction time, reaction temperature and partial pressure of oxygen on the ratio of ...

The Recovery of Valuable Metals from Ocean Polymetallic Nodules Using Solid-State Metalized Reduction Technology

, 2019
Ocean polymetallic nodules are oxide ores rich in Ni, Co, Cu, and Mn, which are valuable metals found in deep-sea mineral resources. Such non-ferrous metals do not exist in isolation, and producing concentrates using conventional mineral separation ...
