ABSTRACT. Performance tests of a manganese nodule crusher of a pilot mining robot, MineRo-II, are carried out to investigate nodule breaking ability of the crusher. Manganese nodules should be crushed into smaller pieces in order to assure the slurry flow of lifting system. In this study, artificial nodules are used instead of real nodules. Artificial nodules are made of …

On 7 March 1873, the deep-sea minerals, i.e., PMN, were primarily discovered by the H.M.S. (Her Majesty's Ship) challenger expedition, described as 'peculiar black oval bodies about 1 in. long' and 'almost pure manganese oxide' (Sharma, 2024).In 1965, Mero recognized their economic potential and predicted that 'deep-sea mining would commence in 20 years' (Mero, 1965).

After primary crushing, manganese ore goes through another stage called secondary crushing. It involves using a finer crusher or grinder to crush the particles into smaller sizes. The grinding and classification method separates manganese ore into particles of different sizes through grinding and classification for further processing.
