The Ministry of Metallurgical Industry manganese ore dressing team visited Japan in December 1980 to explore 6 beneficiation plants, 3 universities and 1 research institute. By examining the current situation and characteristics of manganese ore beneficiation in Japan, we have a brief introduction as follows. First, the status of mineral processing Japan’s manganese ore is mainly distributed in Hokkaido and Benzhou two islands, the highest annual production of 350,000 tons, due to resource depletion and economic reasons, now including finished rich ore and concentrate production has dropped to 100,000 Ton
