| Research Abstract |
The authors proposed the concept of Seafloor Mineral Processing, where ores excavated on seafloor are in situ ground to separate useful minerals, to promote the development of Seafloor Massive Sulfides (SMSs). The possibility of candidates for grinding and flotation as elemental technologies of Seafloor Mineral Processing was clarified. If Seafloor Mineral Processing is realized based on the results of this study, the mining cost of SMSs could be saved in comparison with the conventional mining scheme that all excavated ores are lifted up.
