    Eksploatacja złóż polimetalicznych konkrecji z dna oceanu
    (Wydawnictwa AGH, 2011) Abramowski, Tomasz; Szelangiewicz, Tadeusz
    Polymetallic nodules discovered in 19th century become the potential resources of the metal ore. Very large depths, the possibility of harsh weather conditions and long distances to the shore causes that the exploitation at industry scale becomes the technically difficult and expensive venture. In the paper several different concepts for nodule mining systems together with problems which have to be solved before exploitation were presented.
