人工合成的１ｎｍ锰矿相和铜、钴、镍等二价金属阳离子的交换实验表明，１ｎｍ锰矿相具有强烈的金属阳离子交换能力。正是这种金属阳离子的交换能力，使得大洋多金属结核大量地富集了铜、钴、镍等有价金属元素。１ｎｍ锰矿相对几种金属阳离子的交换的优先顺序为：Ｃｕ＞Ｃｏ＞Ｚｎ≥Ｎｉ＞Ｃａ＞Ｍｇ。多金属结核中镍的含量往往高于铜、钴、锌等元素，但在交换顺序中它却低于铜、钴、锌等，这种不一致性说明结核成矿后期的金属离子交换并非是有价金属结合进结核的唯一途径。多金属结核富含铜、钴、镍等有价金属可能是结核初始成矿和成矿后期金属离子交换等多种因素共同作用的结果。
The exchange experiments of synthetic 1nm manganese ore phase and copper, cobalt, nickel and other divalent metal cations show that 1nm manganese ore phase has a strong ability of metal cation exchange. It is the exchange capacity of this metal cation that has enabled the polymetallic nodules of the oceans to enrich abundantly the valuable metal elements such as copper, cobalt and nickel. 1nm manganese relative to several metal cation exchange priority order: Cu> Co> Zn> Ni> Ca> Mg. The content of nickel in polymetallic nodules is often higher than those of copper, cobalt and zinc, but it is lower than that of copper, cobalt and zinc in the exchange order. This inconsistency indicates that the metal ion exchange in the late stage of mineralization is not The only way for the valence metals to bind to TB. Polymetallic nodules rich in copper, cobalt, nickel and other valuable metals may be the result of the combination of many factors, such as the initial mineralization of the tuberculosis and the metal ion exchange in the late stage of mineralization.
