Abstract

Un procedimiento para la extracción de valores de Ni/Co apartir de mena o concentrado, el cual comprende las siguientes etapas: someter la mena o concentrado a oxidación por presión en presencia de oxígeno y una solución ácido conteniendo iones de haluro, cobre y sulfato para obtener un licor conteniendo valores de Ni/Co provenientes de la suspensión resultante de oxidación por presión; someter el licor a un tratamiento de precipitación selectiva para obtener un sólido conteniendo hidróxido de Ni/Co y someter el sólido a una etapa de lixiviación de Ni/Co con una solución de amonio para producir una solución de lixiviación conteniendo valores de Ni/Co y un residuo.Un procedimiento de acuerdo a la reivindicación 1, el cual comprende las siguientes etapas: someter el residuo a una etapa de lavado ácida para producir una solución de lavado conteniendo valores de Ni/Co y un residuo desechable y reciclar la solución de lavado al tratamiento de precipitación selectiva.A procedure for the extraction of Ni / Co values from ore or concentrate, which comprises the following steps: subjecting the ore or concentrate to pressure oxidation in the presence of oxygen and an acid solution containing halide, copper and sulfate ions to obtain a liquor containing Ni / Co values from the suspension resulting from pressure oxidation; subjecting the liquor to a selective precipitation treatment to obtain a solid containing Ni / Co hydroxide and subjecting the solid to a Ni / Co leaching step with an ammonia solution to produce a leaching solution containing Ni / Co values and A residue according to claim 1, which comprises the following steps: subjecting the residue to an acidic washing step to produce a washing solution containing Ni / Co values and a disposable residue and recycling the washing solution to selective precipitation treatment.
