Abstract

SE PROPORCIONAN UN MÉTODO Y DISPOSITIVO DE RECUPERACIÓN INTEGRAL DE ESCORIAS DE FUNDICIÓN DE COBRE. EL MÉTODO UTILIZA UN HORNO CR PARA REALIZAR LA REDUCCIÓN POR GASIFICACIÓN Y SEDIMENTACIÓN DE LA ESCORIA DE FUNDICIÓN PARA RECUPERAR EXHAUSTIVAMENTE LOS METALES VALIOSOS EN LA ESCORIA DE FUNDICIÓN Y PRODUCIR ESCORIA INOFENSIVA. EL HORNO CR (30) INCLUYE UNA LA CAVIDAD INCLUYE UNA CÁMARA DE REDUCCIÓN POR GASIFICACIÓN (31) Y UNA CÁMARA DE SEDIMENTACIÓN (32) EN COMUNICACIÓN UNA CON LA OTRA. EL PASO DE LA RECUPERACIÓN DE LOS METALES VALIOSOS EN LA ESCORIA DE FUNDICIÓN INCLUYE: REALIZAR UN TRATAMIENTO REDUCTIVO POR GASIFICACIÓN DE LA ESCORIA DE FUNDICIÓN EN LA CÁMARA DE REDUCCIÓN POR GASIFICACIÓN (31) PARA OBTENER POLVO DE HUMO DE METAL VALIOSO Y ESCORIA REDUCIDA, Y REALIZAR UN TRATAMIENTO DE SEDIMENTACIÓN EN LA ESCORIA REDUCIDA EN LA CÁMARA DE SEDIMENTACIÓN (32) PARA OBTENER MATA DE COBRE Y ESCORIA INOFENSIVA; O REALIZAR UN TRATAMIENTO DE SEDIMENTACIÓN DE LA ESCORIA DE FUNDICIÓN EN LA CÁMARA DE SEDIMENTACIÓN (32) PARA OBTENER MATA DE COBRE Y ESCORIA SEDIMENTADA, Y REALIZAR UN TRATAMIENTO REDUCTIVO POR GASIFICACIÓN EN LA ESCORIA SEDIMENTADA EN LA CÁMARA DE REDUCCIÓN POR GASIFICACIÓN (31) PARA OBTENER POLVO DE HUMO DE METAL VALIOSO Y ESCORIA INOFENSIVA.A METHOD AND DEVICE FOR THE COMPREHENSIVE RECOVERY OF COPPER FOUNDRY SLUGS ARE PROVIDED. THE METHOD USES A CR FURNACE TO PERFORM THE REDUCTION BY GASIFICATION AND SEDIMENTATION OF THE FOUNDRY SLAG TO EXHAUSTIVELY RECOVER THE VALUABLE METALS IN THE FOUNDRY SLAG AND PRODUCE HARMFUL SLAG. THE CR OVEN (30) INCLUDES A CAVITY INCLUDES A GASIFICATION REDUCTION CHAMBER (31) AND A SEDIMENTATION CHAMBER (32) IN COMMUNICATION WITH ANOTHER. THE STEP OF RECOVERING VALUABLE METALS IN THE FOUNDRY SLAG INCLUDES: PERFORMING A REDUCTIVE TREATMENT BY GASIFICATION OF THE FOUNDRY SLAG IN THE REDUCTION CHAMBER BY GASIFICATION (31) TO OBTAIN VALUABLE AND REDUCED METAL SMOKE POWDER AND SLUG PERFORM A SEDIMENTATION TREATMENT ON THE REDUCED SLAG IN THE SEDIMENTATION CHAMBER (32) TO OBTAIN COPPER MATT AND INOFENSIVE SLAG; OR CARRY OUT A SEDIMENTATION TREATMENT OF THE FOUNDRY SLAG IN THE SEDIMENTATION CHAMBER (32) TO OBTAIN COPPER MATTE AND SEDIMENTED SLAG, AND PERFORM A REDUCTIVE TREATMENT BY GASIFICATION ON THE SLAG SEDIMENTED IN THE REDUCTION CHAMBER (31) GET VALUABLE METAL SMOKE POWDER AND HARMFUL SLAG.
