Abstract

QUE COMPRENDE: a) FUNDIR UN CONCENTRADO DE Pb TSL DE UN MATERIAL DE ALIMENTACION QUE CONTIENE Pb PARA PRODUCIR UN PRODUCTO DE Pb Y UNA ESCORIA QUE CONTIENE Pb; b) SOMETER LA ESCORIA DE (a) A INYECCION DE LANZA CON LA PARTE SUPERIOR SUMERGIDA (TSL), DE GAS QUE CONTIENE OXIGENO Y COMBUSTIBLE, A TRAVES DE UNA LANZA SUSPENDIDA VERTICALMENTE QUE TIENE SU EXTREMO DE PUNTA INFERIOR SUMERGIDO EN LA ESCORIA, PARA GENERAR UNA ZONA DE COMBUSTION EN LA ESCORIA EN LA CUAL EL COMBUSTIBLE SE HACE ENTRAR EN COMBUSTION Y PARA GENERAR CONDICIONES QUE FORMAN UN REVESTIMIENTO DE ESCORIA EN EL EXTREMO INFERIOR DE LA LANZA QUE SE SOLIDIFICA POR EL EFECTO ENFRIANTE DEL GAS INYECTADO, Y EN DONDE LA INYECCION TSL SE LLEVA EN CONDICIONES REDUCTORAS, USANDO UN MATERIAL SULFUROSO COMO REDUCTOR, PARA REDUCIR EL Pb EN LA ESCORIA A Pb METALICO Y ASI FORMAR UNA FASE DE Pb FUNDIDO QUE SE TOMA COMO Pb BULLION; Y, c) CONVERTIR EN HUMO DE ESCORIA. EL MATERIAL DE ALIMENTACION ES CONCENTRADO DE Pb, FUENTES DE Pb SECUNDARIAS QUE INCLUYEN BATERIAS ACIDAS DE Pb, METAL QUE CONTIENE Pb RECICLADO. EL MATERIAL SULFUROSO ES CONCENTRADO A GRANEL TAL COMO CONCENTRADO A GRANEL DE Pb/Zn/Ag, UN CONCENTRADO DE Pb o Zn, DESECHOS SULFURICOS Y PIRITAS. LA REDUCCION SE REALIZA SIN USAR REDUCTOR CARBONACEO EXCEPTO EL PRESENTE EN EL MATERIAL SULFUROSO. (a) Y (b) SE REALIZAN EN HORNOS TSL RESPECTIVOS O POR LOTES EN UN SOLO HORNO TSL; Y (c) EN UN SEGUNDO HORNO TSL. (a) SE REALIZA ENTRE 950°C Y 1200°C, Y (b) ENTRE 1200°C Y 1250°CWHICH INCLUDES: a) MELTING A Pb TSL CONCENTRATE FROM A FEED MATERIAL CONTAINING Pb TO PRODUCE A Pb PRODUCT AND A Pb-CONTAINING SLAG; b) SUBMIT THE SLAG FROM (a) TO LACE INJECTION WITH THE UPPER PART SUBMERGED (TSL), OF GAS CONTAINING OXYGEN AND FUEL, THROUGH A VERTICALLY SUSPENDED LANCE THAT HAS ITS LOWER POINT END SUBMERGED IN THE SLUG TO GENERATE A COMBUSTION ZONE IN THE SLUM IN WHICH THE FUEL IS MADE TO ENTER COMBUSTION AND TO GENERATE CONDITIONS THAT FORM A SLAG COATING AT THE LOWER END OF THE LANCE THAT IS SOLIDIFIED BY THE COOLING EFFECT OF THE INJECTED GAS, AND IN DON'T TSL INJECTION IS CARRIED IN REDUCING CONDITIONS, USING A SULFUROUS MATERIAL AS REDUCER, TO REDUCE THE Pb IN THE SLAG TO METALLIC Pb AND THUS FORM A MELTED Pb PHASE THAT IS TAKEN AS Pb BULLION; And, c) TURN INTO SLAUGH SMOKE. THE FEED MATERIAL IS Pb CONCENTRATED, SECONDARY Pb SOURCES INCLUDING ACID Pb BATTERIES, METAL CONTAINING RECYCLED Pb. THE SULFIDE MATERIAL IS A BULK CONCENTRATE SUCH AS A BULK CONCENTRATE OF Pb / Zn / Ag, A CONCENTRATE OF Pb or Zn, SULFURIC WASTE AND PYRITES. THE REDUCTION IS CARRIED OUT WITHOUT USING THE CARBONACE REDUCER EXCEPT FOR THE PRESENT IN THE SULFIDE MATERIAL. (a) AND (b) ARE CARRIED OUT IN RESPECTIVE TSL OVENS OR BY BATCHES IN A SINGLE TSL OVEN; AND (c) IN A SECOND TSL OVEN. (a) PERFORMED BETWEEN 950 ° C AND 1200 ° C, AND (b) BETWEEN 1200 ° C AND 1250 ° C
