According to the existence of manganese, an experiment was carried out by adopting a processing technique consisting of reduction roasting and acid leaching to treat high-silicon manganese oxide ore. The effects of roasting temperature, roasting time, mass ratio of coal to ore, leaching temperature and time, initial sulfuric acid concentration, and liquid-solid ratio on the manganese leaching rate were all investigated. The results show that the leaching rate of manganese can reach 95.83% under the conditions including roasting temperature of 880 ℃, roasting time of 1.5 h, a mass ratio of 18% for coal to ore, leaching temperature of 55 ℃, leaching time of 2 h, initial sulfuric acid concentration of 1.80 mol/L, as well as liquid-solid ratio of 5 mL/g.
