Manganese Nodules and Cobalt-rich Crusts | Cobalt Institute

On sediment-starved deep ocean floors, generally 4 to 5.5 kilometres deep, concretions rich in manganese, cobalt and nickel can form around small fragments of debris and organic material. The nodules concentrate minerals from siliceous oozes and from the water column.

Manganese nodule - Infogalactic: the planetary knowledge core

Kennecott Copper had explored the potential profits in manganese nodule mining and found that it was not worth the cost. On top of the environmental issues and the fact that the profits had to be shared, there was no cheap way to get the manganese nodules off the sea floor. [citation needed] In the meantime, interest in the extraction of ...

This is thought to produce nodules with similar iron and manganese content and a relatively high grade of nickel, copper and cobalt. 2. A diagenetic process in which the manganese is remobilized in the sediment column and precipitates at the sediment/water interface. Such nodules are rich in manganese but poor in iron and in nickel, copper and ...

Manganese Nodule - an overview | ScienceDirect Topics

Manganese-nodule fields are among the more spectacular features that have been discovered on the deep-sea floor (Fig. 9.31). They vary largely in size (from micronodules to more than meter size), shape (from spherical to ellipsoidal to tabular), surface texture (from smooth to botryoidal to rough) and abundance (Glasby, 2006). Micronodules are ...
