Abstract

In order to understand the change of chemistry of manganese deposits under early diagenetic environment, reduction of manganese nodules analogous to natural diagenetic reduction was experimentally examined. A series of run with 1/1000 mineral/solution weight ratio was carried out with changing temperature, type and concentration of reducing agents, and type and concentration of acid/base and/or buffering agents. The experimental results indicate that the concentration of Mn, Co, Ni and Cu in solution increases with increasing of reducing agents. Change of chemical composition of nodules and dissolution of trace elements with reduction are presented with discussion.
