富钴结壳是一种潜在的多金属资源,富含Co、REEs、Pt、Te等。其中,Ce的含量特别高,具有较高的经济价值,研究其富集的控矿要素具有重要意义。Takahashi等(2007)认为富钴结壳中Ce的富集是一个动力学过程,富钴结壳生长速度是关键因素。赤道印度洋和西北太平洋富钴结壳的生长速率分别为2.48mm/a和1.78mm/a,尽管其生长速率差别不大,但是其Ce含量却有 Cobalt-rich crust is a potential polymetallic resource, rich in Co, REEs, Pt, Te and so on. Among them, the content of Ce is particularly high and has high economic value. It is of great significance to study the enrichment of its ore-controlling elements. Takahashi et al. (2007) concluded that the enrichment of Ce in cobalt-rich crusts is a kinetic process and the growth rate of cobalt-rich crusts is the key factor. The growth rates of cobalt-rich crusts in the equatorial Indian Ocean and the western North Pacific are 2.48 mm / a and 1.78 mm / a, respectively, although their growth rates are not significantly different
