To provide a method of producing a manganese raw material and a method of producing a manganese-containing steel capable of reducing a refining cost of manganese-containing molten iron by recovering the manganese raw material having a low impurity concentration from a manganese oxide-containing material.SOLUTION: The method of producing the manganese raw material includes a grinding step (S100) for producing, using the manganese oxide-containing material containing at least manganese, calcium, silicon and phosphorus as a raw material, a ground manganese oxide-containing material by grinding the manganese oxide-containing material, an underwater magnetic separation step (S102) for separating, by dispersing the ground manganese oxide-containing material in water and applying a magnetic field to the water containing the ground manganese oxide-containing material, into a magnetic material and a non-magnetic material, and a step (S104) for recovering the magnetic material separated at the underwater magnetic separation step as the manganese raw material.SELECTED DRAWING: Figure 1
