Provided is a method for smelting a nickel-containing oxide ore with which the amount of CO2 generated is reduced and the nickel recovery rate is high. The present invention is a method for smelting a nickel-containing oxide ore, the method comprising: a step for using a tubular reaction vessel, introducing a raw material that contains a nickel-containing oxide ore so as to move from above to below within the reaction vessel, and supplying a hydrogen-containing gas as a reducing agent to the raw material from below and from the side to perform a reduction treatment; a step for performing a melting treatment on the reduction product obtained using the reduction treatment; and a step for separating the slag from the melt obtained using the melting treatment and recovering a nickel-containing metal. The gas supplied from below to the raw material is supplied at room temperature. The gas supplied from the side to the raw material is at a temperature of 300C or higher and is supplied from the side at a position above the position where the raw material for which the reduction treatment has been completed is stored.
