    The solubility and complexation of Niobium in hydrothermal fluids by Haotian Liu, Xing Ding, Haibo Yan, Kaixuan Liu, Junfeng Liu, Xiaolong Huang

    Published 2024-03-01
    “…Metal dissolution, complexation, and speciation are the key processes that facilitate metal mobilization and transport in fluids. Niobium (Nb), a kind of critical metal, has traditionally been regarded as a fluid-immobile element; however, it sometimes shows apparent hydrothermal mobility and even mineralization. …”
