The method of reduction processing of steel-making slag, includes: a hot steel-making slag inflow process of continuously or intermittently charging, from a slag supplying container, hot steel-making slag to a molten slag layer on a molten iron contained in an electric furnace while adjusting an amount of inflow with the slag supplying container; a reducing agent supplying process of supplying a reducing agent to the molten slag layer; an electrifying and heating process of heating the molten iron and the molten slag layer through application of electric power; and a reduction process of continuing reduction processing of the hot steel-making slag in a non-oxidizing atmosphere while intermittently discharging either one or both of the molten iron or molten slag of the molten slag layer.
