<p>A method of recovering copper and iron from copper smelter slag according to the present invention comprises; a matte concentration step for feeding iron sulfide and carbon into a reactant collected from the copper smelter slag and concentrating to an intermediate product of copper matte; a separation step for separating matte produced through the matte concentration step from the slag; a copper recovery step for recovering copper by recovering copper matte produced through the matte concentration step using a copper smelter process; a desulphurization step for removing sulfur by injecting oxygen into the slag separated through the separation step; and an iron recovery step for recovering iron by extracting pig iron by feeding carbon into the reactant with sulfur removed through the desulphurization process. [Reference numerals] (AA) START; (BB) END; (S101) Matte concentration step; (S103) Separation step; (S105) Copper recovery step; (S105') Desulphurization step; (S107) Iron recovery step</p> |
