Abstract

PROCEDIMIENTO CONTINUO DE ATAQUE OXIDANTE EN CALIENTE DE UN MINERAL URANIFERO (CERFIFICADO DE ADICION DE LA PATENTE N 493.662). CONSISTE EN ATACAR UN MINERAL URANIFERO QUE CONTIENE IMPUREZAS ARSENICALES, EN PRESENCIA DE UN OXIDANTE, POR MEDIO DE UN LIQUIDO ACUOSO QUE CONTIENE CARBONATO Y BICARBONATO ALCALINOS Y URANIO CERCA DE SU LIMITE DE SOLUBIDAD, A PRESION Y TEMPERATURA ADECUADAS. ENFRIAR Y SEPARAR LAS FASES SOLIDA Y LIQUIDA; RECIRCULAR ESTA Y TRATAR LA FASE SOLIDA PARA REDISOLVER EL URANIO, PRECIPITANDO EL ARSENICO SOLUBILIZADO MEDIANTE MAGNESICO, EN FORMA DE ARSENIATO DE MAGNESIO. TIENE APLICACIONES PARA LA DEPURACION SELECTIVA DE MATERIAS ARSENICALES EN EL ATAQUE OXIDANTE DE UN MINERAL DE URANIO.
