Abstract
1. PROCESO PARA LA REDUCCION Y FUNDICION DE MINE- RALES O POLVO DE LATERITA CON CONTENIDO DE NIQUEL PARA PRODUCIR UN FERRONIQUEL NO REFINADO, Y DONDE COMO MINIMO EL 20% EN PESO DE LA LATERITA TIENE UN TAMANO INFERIOR A 10 mm, PROCESO QUE EN FORMA DE LATERITA CON CONTENIDO DE NIQUEL PREVIAMENTE REDU- CIDA O BIEN EN FORMA DE LATERITA CON CONTENIDO DE NIQUEL SIMULTANEAMENTE CON UN AGENTE REDUCTOR CAR- BONOSO, EN LA REGION CENTRAL DEL BANO EN FUSION DE UN HORNO CILINDRICO DEL TIPO DE HORNO EN ARCO DE C.C. (CORRIENTE CONTINUA) CON UNO O MAS ELECTRODOS SITUADOS EN LA BOVEDA ACTUANDO COMO CATODO Y EL BANO EN FUSION ACTUANDO COMO CATODO Y EL BANO EN FUSION ACTUANDO COMO ANODO, ALIMENTACION DEL HORNO QUE TIENE LUGAR DE FORMA CONTINUA; Y LA EXTRACCION PERIODICA O CONTINUA DE ESCORIA EMPOBRECIDA DE NI- QUEL Y FERRONIQUEL DEL HORNO. FIGURA 11. PROCESS FOR THE REDUCTION AND CASTING OF MINERALS OR LATERITE POWDER WITH NICKEL CONTENT TO PRODUCE A NON-REFINED FERRONIQUEL, AND WHERE AT LEAST 20% BY WEIGHT OF THE LATERITE HAS A SIZE LESS THAN 10 mm LATERITE FORM WITH PREVIOUSLY REDUCED NICKEL CONTENT OR LATERITE FORM WITH NICKEL CONTENT SIMULTANEOUSLY WITH A CARBON REDUCING AGENT, IN THE CENTRAL REGION OF THE BATH IN FUSION OF A CYLINDRICAL OVEN OF THE TYPE OF ARC OVEN IN CC (CONTINUOUS CURRENT) WITH ONE OR MORE ELECTRODES LOCATED IN LA BOVEDA ACTING AS A CATODE AND THE FUSION BATH ACTING AS A CATODE AND THE FUSION BATH ACTING AS ANODE, FEEDING THE FURNACE WHICH CONTINUOUSLY PLACES; AND THE PERIODIC OR CONTINUOUS EXTRACTION OF EMPOWERED SLAG OF NICKEL AND FERRONIQUEL DEL HORNO.
