Abstract: The beneficiation process of high intensity magnetic separation for -30 mm run-of-mine ore and the ferromanganese alloy production technology of Dounan Manganese Mine are presented.The production practice shows that, from a run-of-mine ore grading 17.50%, a manganese concentrate which have a grade of 28.00% and recovery of 88.00% can be obtained.The advanced technologies such as duplex shaking ladle process for medium carbon ferromanganese and composite pellet technique are adopted.The technical indexes of its high carbon ferromanganese, manganese-silicon alloy and medium carbon ferromanganese products all have reached a high level, establishing the position of Doudan Manganese Mine in China's iron alloy industry.

Key words: Manganese carbonate ore, New generation of high intensity permanent magnetic separator, Ferromanganese alloy production process
