01-06-1983· The potential economic costs of cartelization could be substantial in the case of manganese, but are probably not significant for cobalt, copper or nickel. 23 If manganese supplies from deep-sea nodules prevent prices from rising above current levels, it is estimated that the net economic benefit to the USA would be between $750 million and $1.1 billion (1978 dollars).

Manganese nodule Wikipedia

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.

Manganese nodules « World Ocean Review

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.

The economics of mining seabed manganese nodules: A

We present an economic appraisal and strategy for mining of nodules from the Indian Ocean Nodule Field- one of the four economically potential areas in the world oceans. In contrast to the prevailing perception of non-viability of nodule mining, our analysis indicates a fair degree of economic feasibility and commercial sustainability to mine the deep-sea manganese nodules.

Manganese Nodule Mining and Economic Rent

In the case of manganese nodules both kinds of barriers may exist. If commercially exploitable nodules are not a "free good" but are scarce, such scarcity could permit the creation of economic rent by miners. And if there exist barriers to entry into nodule mining, the conditions for increasing such economic

The Potential Pros and Cons of Seabed Mining JSTOR Daily

Interest in seabed mining has mostly focused on the iron manganese nuggets (nodules) that are abundant in many areas of the deep sea. These odd objects were first discovered during sailing expeditions in the 1870s and early twentieth century, when the little metal balls were scooped up in bottom survey nets.
