Abstract

CARACTERIZADO PORQUE COMPRENDE: a) LA INTRODUCCION DE LA MATA DE NIQUEL-COBRE FUNDIDA EN UNA VASIJA PIROMETALURGICA; b) LA INTRODUCCION DE UN GAS OPERATIVO ENRIQUECIDO CON NITROGENO A LA VASIJA PARA CONTROLAR LA TASA DE OXIDACION HACIA EL FINAL DEL CICLO DE CONVERSION DE LA MATA BEISEMER Ni/Cu, DE MINIMIZAR LA FORMACION DEL MINERAL MUSH, DE REGULAR LA TEMPERATURA DE CONVERSION Y LA COMPOSICION DE LA MATA DURANTE LAS ULTIMAS ETAPAS DE LA CONVERSION ASI COMO DE ACELERAR EL ENFRIAMIENTO DE LA MATA A UNA TEMPERATURA CONSISTENTE CON UN BUEN DESESCORIAMIENTO, FUNDICION Y POSTERIOR PROCESO DE REFINACIONCHARACTERIZED BECAUSE IT INCLUDES: a) THE INTRODUCTION OF THE MATTED NICKEL-COPPER MATT IN A PYROMETALLURGICAL VESSEL; b) THE INTRODUCTION OF AN OPERATING GAS ENRICHED WITH NITROGEN TO THE VESSEL TO CONTROL THE OXIDATION RATE TO THE END OF THE MATA BEISEMER Ni / Cu CONVERSION CYCLE, TO MINIMIZE THE FORMATION OF MINERAL MUSH, WITH REGULATING TEMPERATURE AND THE COMPOSITION OF MATA DURING THE LAST STAGES OF THE CONVERSION AS WELL AS ACCELERATING THE COOLING OF THE MATA TO A TEMPERATURE CONSISTENT WITH A GOOD DESCORING, MELTING AND SUBSEQUENT REFINING PROCESS
