Abstract
La presente invención está dirigida a un proceso híbrido usando resina de intercambio iónico en un proceso selectivo de recuperación de níquel y cobalto desde efluentes lixiviados, que está compuesto de los pasos de: procesamiento (1) del mineral de laterita (M), el cual es luego tratado mediante lixiviación (2) (ya sea a presión atmosférica o bajo presión), considerando las soluciones provenientes del paso de separación sólido-líquido de las instalaciones ya existentes en funcionamiento (2) también, de manera que el proceso corriente abajo comprende un circuito híbrido de intercambio iónico, donde el primer paso de intercambio iónico (3) con resinas (Re) muestra condiciones de selectividad específicas para la extracción de hierro, aluminio y cobre y un aumento del pH, y el segundo paso de intercambio iónico (4) permite la extracción de níquel y cobalto.The present invention is directed to a hybrid process using ion exchange resin in a selective process of recovering nickel and cobalt from leached effluents, which is composed of the steps of: processing (1) of laterite ore (M), which It is then treated by leaching (2) (either at atmospheric pressure or under pressure), considering the solutions coming from the solid-liquid separation step of existing facilities in operation (2) as well, so that the downstream process comprises a hybrid ion exchange circuit, where the first ion exchange step (3) with resins (Re) shows specific selectivity conditions for the extraction of iron, aluminum and copper and an increase in pH, and the second ion exchange step ( 4) allows the extraction of nickel and cobalt.
