Seafloor and oceanic crust are geologically young compared with continental crust, and hydrothermal vents are located at extensional tectonic setting. Ore deposit within the seafloor could be estimated to form at shallower part compared with ore deposit in land, even for open and/or hidden deposits. According to geological characteristics of seafloor ore deposits, active mining technology, which is applied by hydrogen reduction system of metal sulfide, was studied.Pyrite (representative iron sulfide) could be reduced into pyrrhotite and magnetite by hydrothermal reaction, and hydrogen sulfide could produce hydrogen by hydrothermal reaction, and then produced sulfur oxides could be converted into hydrogen sulfide mixed with other biomass (or organic compounds). Those results could extend to establish active mining technology.

与陆壳相比，海底和洋壳的地质年龄较小，热液喷口位于伸展构造环境中。可以估计，与陆地矿床相比，海底矿床形成的部位较浅，即使是露天和/或隐伏的矿床也是如此。根据海底矿床的地质特征，研究了金属硫化物氢气还原体系主动采矿技术，通过水热反应将黄铁矿(典型的硫化铁)还原为磁黄铁矿和磁铁矿，硫化氢通过水热反应生成氢气，生成的硫氧化物与其他生物质(或有机化合物)混合转化为硫化氢。这些结果可能会扩展到建立活跃的采矿技术。
