Should Manganese Nodules be Exploited as a Source of Metal? Should we continue exploiting manganese nodules as a source of metal, taking into consideration all the moral aspects.

Manganese nodules are small, dark, potato-shaped mixtures of different minerals, containing sources of useful metals such as manganese, iron, copper, nickel, lead, coat and cobalt. The nodules are form by about 24% of manganese, 15% iron, 1.5% of nickel and smaller abundances of the other elements. Manganese nodules are raise in large quantities in the sea-beds of oceans proximate to the regions of Russia, Brazil, Australia, score Islands, southwesterly Africa, Gabon, India and the Solomon Islands. It is generally found under depths of 2,750 to 4,500 meter of water, crisp ofttimes near tectonic plate boundaries, as it is formed from travel lava solidified between diverging oceanic plates. Therefore, it has a very small growth rate, millimetres per million years. Theyre usually find a few thousand kilometres off the closest Continental shores. In the early 1970s, undersea manganese nodules were considered gold mines. Since the sound aspects of manganese werent clear as the n odules were outside most EEZ s, the UN created the world(prenominal) sea bottom Authority, located in Kingston, Jamaica, to regulate these issues. This memorial tablet has passed down the police force which states that the shoreline of the closest country to the resources has licit rights over it. Manganese was recognised as an element by Bergman Scheele and others and was isolated by J.G. Grahn in 1774 in Stockholm, Sweden.

Manganese is a transition metal that resembles iron; it is greyish white coloured, only its harder and very brittle. It is also chemically reactive, as it decomposes water slowly. Its ther monuclear number is 25, atomic weight is 54.! 938 and atomic symbol is Mn. Its electron configuration is 2-8-13-2 and it has melting and boiling points of 1245ºC and 1962ºC. Manganese plays a vital biological role for humans, as it is essential for salutary skin and strong bone and cartilage formation. Its...
