This article examines the economic implications of mining or of not mining manganese nodules and summarizes potential ecological consequences. Apart from possible net economic benefits to certain countries, mining the nodules is not regarded as an economic or strategic necessity. It is concluded that expansion of basic research on oceanfloor ecosystems must be granted high priority. It is in ...

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 a potential economic interest. Nodules vary in size from tiny particles visible only under a microscopeto large pellets more than 20 centimetres (8 in) across. However, most nodules are between 3 and 10 cm (1 and 4 in) in diameter, ab

Manganese nodules: desired mineral resource and

The aim is to establish a baseline of environmental standards before potential future mining of manganese nodules in the deep sea commences. The area to be investigated by the research project "Mining Impact" is located in the Clarion Clipperton Zone (CCZ) in the northeast Pacific at approximately 4,500 metres water depth shrouded in complete darkness. Here, in an area of five million square ...

Manganese: Nodules, Uses, Facts, Ore, Alloys, Metal

Should deep seabed mining become economic, the sources of manganese ore could significantly shift from land to ocean. The estimated manganese nodule resource dwarfs land-based resources and could greatly diversify worldwide manganese sources. Much of the resource is in international waters. Substantial seabed manganese resources also occur within the U.S. Exclusive Economic Zone and

Manganese nodules « World Ocean Review

After a record high before the economic crisis of 2008, however, the cobalt price has fallen steeply, so that mining of the deposits is not presently economical. Nevertheless, given the large amounts of metals that are contained in the manganese nodules worldwide, it is certainly conceivable that the nodules may be mined in certain marine regions in the future. For many countries that do not ...

In the framework of the Blue Mining project, a potential mine site within E1 was studied (Rahn 2016). Due to its size (255 km2) the exemplary mine site is assumed to represent the characteristics of a potential mining field (Table 1). “The Figure 1.

The Potential Pros and Cons of Seabed Mining JSTOR

29/08/2019  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. Manganese has several commercial uses, especially in important metal alloys
