Abstract
Un método de producir una solución rica en cobre de soluciones de níquel-cobalto que contenga iones niquelosos y cobaltosos, que comprende, proveer una solución de níquel-cobalto de flujo principal en la cual el promedio de níquel a cobalto fluctúa desde alrededor de 5:1 a alrededor de 200:1. extraer una parte alícuota de dicha solución de níquel-cobalto de dicho flujo principal, dicha porción alícuota conteniendo níquel el cual cuando es oxidado al estado niquélico es por lo menos suficiente para oxidar subsiguientemente el cobalto en el flujo principal al estado cobáltico, precipitar dicho níquel de dicha porción alícuota como un precipitado niqueloso por la adición de un agente precipitador seleccionado del grupo consistente en una mezcla de CO2 y NH3 y NH3 solo, siendo la temperatura de precipitación sobre 50 grados C. Cuando se usa NH3 solo, oxidar dicho precipitado niqueloso al estado niquélico, separar dicho precipitado de níquel oxidado de la solución y poniendo en contacto la solución de flujo principal con dicho precipitado oxidado durante un tiempo suficiente para oxidar iones, cobaltosos en dicha solución al estado cobaltico y con ello precipitar el cobalto de la solución y reducir el ión niquélico al estado niqueloso, siendo la temperatura de oxidación sobre 50 grados C. Por lo cual el níquel en la solución de flujo principal es enriquecido substancialmente en relación al cobalto para proveer un promedio de níquel:cobalto en dicha solución de sobre 20000:1.
