The oceans cover more than 70% of the planet, and represent a potentially promising new frontier for the research and exploration of minerals. The exploration of submarine minerals and the characterization of ore deposits requires the use of cutting-edge technology in the field of the marine geology.

The Authority has signed exploration contracts for cobalt-rich crusts with Japan, China and Russia. The experience of metallurgy of polymetallic nodules would help extracting metals from the cobalt crusts, however, the mining technology for these deposits is likely to be more complex than the polymetallic nodules. According to the EPRS, the daily cost of an exploration vessel can reach €,, while most exploration trips require a budget of between $50 million and $ million. To take one example, the initial capital costs for Papua New Guinea’s Solwara project, which lies at lesser depths, are estimated at $ million.
Y.E. Lee, in Encyclopedia of Materials: Science and Technology, (a) Standard ferromanganese. Standard ferromanganese, also known as high-carbon ferromanganese, is one of the manganese ferroalloys smelted directly from manganese ese content ranges from 74 to 82% and the carbon content from 7 to %. It is produced either by a blast . Tungsten has often been reported in marine ferromanganese deposits and the question arises as to how the large oxyanionic species (WO 4 2-) enters the appropriate phases. Very low W concentrations in seawater (less than μg/kg) suggest that it is not directly related to precipitation processes. Of all the comparable marine samples, manganese Cited by:

The marine manganese deposits (MMD) include manganese nodules (also called polymetallic nodules or ferromanganese nodules), slab-type ferromanganese encrustations, and cobalt-rich crusts.
Although first recovered in from the Kara Sea, off Russia (erstwhile the USSR), probably the first detailed scientific investigation of MMD was. ABSTRACT Progress in marine hard mineral exploration and exploitation has been severely restricted by technologic gaps and the lack of discovery of deposits that can be exploited at a competitive price in the world markets.
Immediate needs include imCited by: 1. Abstract. Marine iron manganese deposits show a greater chemical variability than was realized only 10 years ago.
As a consequence correct conclusions regarding the genesis of a given deposit frequently require knowledge about several geochemical parameters and preferably about accumulation rates and spatial relations vis-a-vis e.g.

Marine ferromanganese crusts and nodules host high concentrations of many economically interesting metals such as platinum (Pt), with Pt concentrations in the range of. Ferromanganese deposits cover about 46 million km 2 of the ocean floor, at water depths ranging from 3 to 6 km.
The nodule deposits are typical two‐dimensional bodies, most commonly occur at the sediment–water interface and vary in abundance from being thinly scattered in some places to densely populated in other areas, often exceeding The book includes a synthesis of research findings on the structure and evolution of the Central Indian Ocean Basin and its ferromanganese deposits, in particular, on the exploration campaign since s.
A comprehensive mixture of recent studies along with classical theories starting from the s is the hallmark of the book. The MarineE-tech team are planning a research expedition to the northeast Atlantic next year to discover what controls the richness of the deep-sea deposits which arise on seamounts and assess novel exploration methods and potential effects of disturbance of these sensitive marine environments.

Proceedings of the September Workshop held in Kingston, Jamaica. Manganese mineralization is diverse in occurrence, origin, mineralogy and geochemistry. These variations reflect differences in the processes of formation and depositional environments, which in turn are a response to changes in the land-ocean-atmosphere system over geological time.
As such, manganese deposits can act as markers of major events in the dynamic evolution of. Exploration for, and potential extraction of, deep-ocean mineral deposits poses many geological, technical, environmental and economic challenges, as well as regulatory and philosophical questions.
Great uncertainty exists, and the development and stewardship of these deposits requires an incremental approach, encouraging transparency and. Preface for Ore Geology Reviews Special Issue: Marine mineral deposits: New resources for base, precious, and critical metals James R.
Hein, Georgy A. Cherkashov Pages The mineral and chemical compositions of a set of crust samples collected from the North, Central and South Atlantic were examined by means of analytical electron microscopy and ICP-MS, chemical, and microchemical elemental analysis.

Their thickness varies from less than 1 millimetre to about millimetres. They occur only where the rock surfaces are free of sediment. There, they form pavements of intergrown manganese and iron oxides.
