Seafloor Massive Sulfide

In Papua New Guinea (PNG), a seafloor massive sulfide (SMS) mining venture has been proposed to start in 2013 and the expected high profitability was presented. However, the geophysical and social conditions are quite different from Japan’s ones. The technologies and model used for the PNG mining are difficult to apply under Japan’s conditions. The economy of SMS mining has no reality in Japan, because the tailing waste disposal is very expensive. Based on a preliminary economic evaluation of seafloor massive sulfide mining venture under Japan’s conditions, some modifications in the mining system and material flow are proposed for the improvement of the economy.

Disposal Cost

Because of the higher Au, Ag, and Cu contents, seafloor massive sulfides (SMS) have received much attention as future commercial mining targets by private companies and nations. One of them, Solwara 1 Project in Papua New Guinea (PNG), is scheduled to start the commercial mining operation from 2018. Because the mining site is inter-island area and almost no cost is necessary for the waste disposal in PNG, the economy of the mining is expected very well. In contrast with this, because all the SMS distribution sites in Japan locate outer ocean areas and the waste disposal cost on land in Japan is very expensive, the economy of SMS mining in Japan is quite negative. In order to overcome the problems, a self-standing riser with flexible link to the sea surface platform and a primary ore separation on the seafloor prior to the ore lift-up are proposed. The improved SMS mining concept named Japan’s model is examined.
