Abstract

METODO PARA EL TRATAMIENTO DEL POLVO DE ACERIA INERTIZANDO O RECICLANDO SUS RESIDUOS Y TRANSFORMANDO EL CINC RECUPERABLE EN OXIDO DE CINC DE ALTA PUREZA. EL METODO COMPRENDE LAS ETAPAS DE (1) DECLRURAR LOS POLVOS DE ACERIA; (B) LIXIVIAR LOS POLVOS DECLORURADOS; (C) SEPARAR LOS CATIONES FERRICOS POR PRECIPITACION; (D) NEUTRALIZAR LA LEJIA RICA EN ZN, DESCARGADA EN FE, Y SEPARAR LA FRACCION INSOLUBLE CARGADA EN ZN Y CATIONES NO FERREOS; (E) SOLUBILIZAR EL PRECIPITADO DE ZN POR LIXIVIACION AMONIACAL O CARBONICO AMONIACAL; (F) PRECIPITAR EL COMPLEJO DE ZN AMONIACAL TRAS ELIMINAR LAS IMPUREZAS; Y (H) LAVAR, SECAR Y CALCINAR EL COMPLEJO DE ZN PARA OBTENER OXIDO DE CINC. ESTE METODO PERMITE APROVECHAR LOS RESIDUOS CONOCIDOS COMO POLVOS DE ACERIA GENERADOS EN LA INDUSTRIA SIDERURGICA. FIGURA 1.
