Abstract

EN DONDE LA PRECIPITACION SE EFECTUA EN REACTORES NO PRESURIZADOS, SIENDO LA TEMPERATURA DE LA SOLUCION DE SULFATO DE ZINC CONSERVADA ENTRE 80°C Y LA TEMPERATURA DE EBULLICION DE LA SOLUCION. UN AGENTE DE NEUTRALIZACION, QUE ELEVA EL pH A POR LO MENOS 2,7, Y UN GAS CONTENIENDO OXIGENO SE ALIMENTAN EN LA SOLUCION Y LA PRECIPITACION SE EFECTUA EN PRESENCIA DE NUCLEOS DE HEMATITA. DICHO AGENTE ES CALCINA, COMPUESTO DE CALCIO o COMPUESTO DE HIDROXIDO. POR LO MENOS 1/5 DE LA HEMATITA GENERADA ES RECIRCULADA COMO NUCLEOS DE HEMATITA
