ABSTRACT The selective reduction of low-grade manganese ore followed by magnetic separation was proposed to produce rich-manganese ore. The optimized parameters include a roasting temperature of 1050°C, a roasting time of 6 h, a manganese ore size of 8–13 mm, and an FC/O ratio of 2.5. The reduction roasting products of low …
