METHOD FOR REDUCING VALUABLE METAL FROM STEELMAKING SLAG AND CEMENT CLINKER PROVIDED FROM THE SAME

摘要

PURPOSE: A method of recovering valuable metals from steel-manufacturing slag and cement clinker obtained therefrom are provided to effectively and economically deal with slag by using slag as cement clinker after recovering valuable metals. CONSTITUTION: A method of recovering valuable metals from steel-manufacturing slag includes following steps: preparing steel manufacture melting slag (1) including valuable metals; consecutively injecting the melting slag into a perpendicular furnace (100) including reductants on valuable metals in order to recover valuable metals included in the melting slag and retrieve residual slag; consecutively ejecting the recovered valuable metals and the residual slag into a hopper (200) positioned in the lower part of the perpendicular furnace; recovering valuable metals ejected into the hopper; and connecting the hopper to the perpendicular furnace or positioning the same directly below the perpendicular furnace.
