Abstract

UN PROCEDIMIENTO DE PRODUCCION DE FERRO-MANGANESO AFINADO. SE INTRODUCE EN UN REACTOR, PROVISTO DE AL MENOS UNA TOBERA DE INYECCION QUE DESEMBOCA EN SU PARTE INFERIOR, SILICO-MANGANESO FUNDIDO, Y LUEGO, PROGRESIVAMENTE, UNA MEZCLA DE CAL Y DE MINERAL DE MANGANESO SOLIDO CON UN GRADO DE OXIDACION MEDIO SUPERIOR A 3 Y, CON PREFERENCIA, COMPRENDIDO ENTRE 3,5 Y 4, Y SE AGITA POR INSUFLACION DE GAS EN LA TOBERA DURANTE AL MENOS TODA LA DURACION DE LA REACCION, Y SE SEPARAN, POR COLADA, LA ESCORIA A BASE DE SILICATO DE CALCIO, QUE CONTIENE TODAVIA DE 20 A 35 % DE MNO, Y EL FERRO-MANGANESO AFINADO.
