    摘要: A direct method for the production of high-grade, high-purity ferromanganese comprising the steps of charging a molten Mn-containing material, a non-carbonaceous reducing agent and a slagging material in a reaction vessel and subjecting the reaction vessel to horizontal eccentric circular motion to mix and agitate the contents of the vessel, whereby the Mn oxide contained in the molten Mn-containing material is reduced by the non-carbonaceous reducing agent.
