    Composition and sorption capacity of oceanic and marine ferromanganese nodules
    PANGAEA
    In:  Supplement to: Novikov, Georgy V; Baturin, Gleb N (1997): Sorption ability of oceanic and marine ferromanganese nodules and crusts of different chemical and mineralogical composition. Translated from Okeanologiya, 1997, 37(4), 525-531, Oceanology, 37(4), 472-478

    Description: Experimental data obtained show that oceanic and marine ferromanganese nodules and crusts are natural ion-exchangers. Exchange capacity of oceanic ferromanganese aggregates is much higher than that of shallow-water marine ones, whereas reactivities of exchange cations (Na, K, Ca, and Mg) are almost equal in both.

    Contents of metal cations exchange capacity of ore minerals in ferromanganese micronodules from the Atlantic, Indian and Pacific Oceans
    PANGAEA
    In:  Supplement to: Novikov, Georgy V; Sval'nov, Vyacheslav N; Bogdanova, Olga Yu; Sivtsov, Alexander V (2010): Ion exchange properties of manganese and iron minerals in oceanic micronodules. Translated from Litologiya i Poleznye Iskopaemye, 2010, 5, 461-476, Lithology and Mineral Resources, 45(5), 410-424, https://doi.org/10.1134/S0024490210050020

    Description: Results of experimental studies of ion exchange properties of manganese and iron minerals in micronodules from diverse bioproductive zones of the World Ocean were considered. It was found that sorption behavior of these minerals was similar to that of ore minerals from ferromanganese nodules and low-temperature hydrothermal crusts. The exchange complex of minerals in the micronodules includes the major (Na**+, K**+, Ca**2+, Mg**2+, and Mn**2+) and subordinate (Ni**2+, Cu**2+, Co**2+, Pb**2+, and others) cations. Reactivity of theses cations increases from Pb**2+ and Co**2+ to Na**+ and Ca**2+. Exchange capacity of micronodule minerals increases from alkali to heavy metal cations. Capacity of iron and manganese minerals in oceanic micronodules increases in the following series: goethite 〈 goethite + birnessite 〈 todorokite + asbolane-buserite + birnessite 〈 asbolane-buserite + birnessite 〈 birnessite + asbolane-buserite 〈 birnessite + vernadite ~= Fe-vernadite + Mn-feroxyhyte. Obtained data supplement available information on ion exchange properties of oceanic ferromanganese sediments and refine the role of sorption processes in redistribution of metal cations at the bottom water - sediment interface during micronodule formation and growth.

    Chemical composition of ferromanganese nodules and surface layer pelagic bottom sediments from the Pacific Ocean

    In:  P.P. Shirshov Institute of Oceanology, Russian Academy of Sciences, Moscow | Supplement to: Novikov, Georgy V; Murdmaa, Ivar O (2007): Ion exchange properties of oceanic ferromanganese nodules and enclosing pelagic sediments. Translated from Litologiya i Poleznye Iskopaemye, 2007, 2, 153-186, Lithology and Mineral Resources, 42(2), 137-167, https://doi.org/10.1134/S0024490207020034

    Description: Results of an experimental study of ion exchange properties of Fe-Mn nodules and deep-sea pelagic host sediments are under consideration. The exchange complex of sediments and nodules includes Na+, K+, Ca2+, and Mg2+ cations. Fe-Mn nodules also include Mn2+ cations. Series of reactivity of metal cations during exchange reactions in different types of pelagic clayey sediments and diagenetic-sedimentary Fe-Mn nodules are compiled. Series of exchange capacity of the sediments and Fe-Mn nodules for alkali and heavy metal cations are also presented. Exchange capacity of the Fe-Mn nodules is always higher than that of the host sediments. The host sediments are characterized by reversible equivalent sorption of cations of both alkali and heavy metals. Irrespective of mineral composition, the Fe-Mn nodules are characterized by reversible equivalent sorption of alkali metal cations, whereas sorption of heavy metal cations is only partly reversible. More over, alkali metal cations do not replace heavy metal cations. The results obtained specify the role of ion exchange processes in redistribution of heavy metal cations at the water - bottom sediment interface during diagenetic-sedimentary formation of Fe-Mn nodules.
