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°C
