Deep sea mining is a mineral retrieval process that takes place on the ocean mining sites are usually around large areas of polymetallic nodules or active and extinct hydrothermal vents at 1, to 3, metres (4, to 12, ft) below the ocean’s surface. The vents create globular or massive sulfide deposits, which contain valuable metals such as silver, gold, copper.

Polymetallic nodules, also called manganese nodules, are rock concretions on the sea bottom formed of concentric layers of iron and manganese hydroxides around a core. As nodules can be found in vast quantities, and contain valuable metals, deposits have been identified as having economic interest.

Get this from a library. Manganese nodule mining and economic rent. [Nina W Cornell; Brookings Institution.]. MANGANESE NODULE MINING AND ECONOMIC RENT. NINA W. CORNELL* The current negotiations on the law of the sea seem likely to answer partially the question of who owns the resources of the oceans.

Ownership has been ambiguous since the days of Grotius. While the actual answer will differ for different parts of the oceans. The existence of manganese (Mn) nodules (Figure 1) has been known since the late s when they were collected during the Challenger expedition of – However, it was not until after WWII that nodules were further studied in detail for their ability to adsorb metals from seawater.

Many of the early studies did not distinguish Mn nodules from Mn crusts. Technological and economic assessment of manganese nodule mining and processing / prepared for U.S. Department of the Interior, Office of Minerals Policy and Research Analysis by Arthur D.

The mining of manganese nodules from the floor of the deep ocean has no historical parallel to draw upon for an evaluation of the possible environmental effects. Mining sites will be located thousands of kilometres from land, on the high seas, with metres of ocean water between the mining platform and the minerals being mined.

viability of nodule mining.” (Glasby ) With the rising metal prices in –, the interest in deep-sea mineral resources experienced a renaissance. Seafloor manganese nodules contain primarily manganese, but also nickel, cobalt, copper, and rare earth elements (Hein ).

Abstract The recent and renewed interest in deep-sea mining relates to the decrease of ore grades of known land-based deposits, the increasing costs in land-based mining, as well as rising metal prices, and an increased demand for strategic metals.

This study examines the economic requirements for future commercial mining projects focusing on manganese nodules.

Manganese nodules are usually located at depths below m and are composed primarily of manganese and iron and elements of economic interest, including cobalt, copper, and nickel and make up a total of around 3% by weight (Margolis and Burns, ). From: Marine Ecotoxicology, Related terms: Iron Oxides; Rare Earth Element.

The mining, pumping and cleaning of the manganese nodules creates noise and vibrations, which disturb marine mammals such as dolphins, and could force them to flee from their natural area. The sediment-laden water produced by the cleaning of manganese nodules is released into the sea from the ships.

A sediment cloud is also created here. A Korean firm plans to start developing a manganese nodule recovery operation in ; the manganese nodules recovered would average 27% to 30% manganese, % to % nickel, 1% to % copper, and % to % cobalt (commercial grade) Nautilus Minerals Ltd.

Living well in the future will require confronting an unjust past. Seabed mining may form only a small part of this struggle, but we ignore the issue at our peril.

Photo by GEOMAR,   Polymetallic nodules (also called as manganese nodules) are small potato-sized (from millimetres to tens of centimetres in diameter) lumps of minerals found in deep sea.

They contain nickel, copper, cobalt, lead, cadmium, vanadium, molybdenum, titanium in various proportions of which nickel, cobalt and copper are considered to be of economic. “Advocates for manganese nodule mining say that the only life at km to 6km deep, where the manganese nodules lie on the seabed, are small ‘head lice’,” she said.

“We know so.Manganese nodules lying on the ocean floor beyond national jurisdiction and containing such strategic minerals as cobalt, copper, manganese and nickel are currently considered to constitute the highest-valued deep ocean mineral resource and regarded by many as the "common heritage of mankind".Reviews: 1.

The economics will turn on nickel, a metal that is both expensive — more than $2 a pound today — and so plentiful in nodules that two companies could be mining 90 percent of what the nation.
