Distribution of Microfossils Within Polymetallic Nodules: Biogenic Clusters Within Manganese Layers

Marine Biotechnology, 2011
Biomineralization is the process by which living organisms or organic matrices produced by them initiate and structure deposition of inorganic polymers/minerals. Deep-sea polymetallic nodules and crusts have recently been recognized as biominerals that are formed around bio-seeds; these deposits are of economic value.

Electrobioleaching of polymetallic ocean nodules

Hydrometallurgy, 2001
Abstract In this paper, a novel electrobioleaching process for recovering valuable non-ferrous metals from ocean nodules is described. The key for successful and efficient dissolution of copper, nickel and cobalt from ocean nodules depends on prior reduction of the manganese and ferric oxides with which the above valuable non-ferrous metals are ...

Mössbauer and ESR Studies of Polymetallic Nodules

physica status solidi (a), 1990
Ces spectres Mossbauer, enregistres a la temperature de l'azote liquide et a temperature ambiante, sont constitues de larges doublets symetriques bien resolus. On montre que deux doublets se chevauchent. Le doublet interieur correspond a Fe 3+ au site tetrahedrique, le doublet exterieur a Fe 3+ au site ...
