Investigation of manganese nodules from the Southern Tasman Sea

Two manganese nodules having a high clay content, a low Mn/Fe ratio, and low contents of valuable metals (Ni 0.25%, Cu 0.17%, Co 0.06%) were recovered in a grab sample during a...

在某次采样作业期间采集的抓样（grab sample）中，回收得到两个锰结核（manganese nodules）；该类锰结核具有高黏土含量、低锰铁比，且有价金属含量偏低，其中镍（Ni）占比0.25%、铜（Cu）占比0.17%、钴（Co）占比0.06%。
