产出于海山表面的富钴结壳是水成成因铁锰氧化物、生物成因组分、碎屑组分等组成的复杂混合物[1,2]。富钴结壳中金属的最终来源有河流和风输入的大陆物质、海底热液活动输入物质、海底玄武岩的风化产物,海底沉积物中释放的金属元素,以及地外物质[2],这些金属部分淋滤进入海水, The cobalt-rich crust produced on seamounts is a complex mixture of hydrothermally formed iron-manganese oxides, biogenic components, detrital components [1,2]. The final source of metals in the cobalt-rich crust is continental matter imported by rivers and winds, hydrothermal input materials from the seabed, weathered products from the seafloor basalts, metal elements released from seafloor sediments, and extra-terrestrial materials [2] Leaching into the sea water,
