Abstract
Un procedimiento industrial para la separación continua de níquel de metales que forman aniones complejos de cloro, especialmente cobalto, por cambio de aniones, en el cual una solución filtrada que contiene cloruro de níquel, preparada disolviendo un concentrado de níquel en una solución de ácido clorhídrico es hervida hasta un contenido de níquel no superior de 240 g/l, preferiblemente 200 g/l, siendo incrementada la concentración de ácido clorhídrico hasta 7 a 8 m/l por adición de ácido sulfúrico concentrado a la solución, en una cantidad equivalente al níquel presente, siendo absorbidas las contaminaciones metálicas en una resina de cambio de aniones, y siendo separados la solución de níquel y el ácido clorhídrico liberados del efluente.An industrial process for the continuous removal of nickel from metals that form complex anions of chlorine, especially cobalt, by exchange of anions, in which a filtered solution containing nickel chloride, prepared by dissolving a nickel concentrate in a hydrochloric acid solution It is boiled to a nickel content of not more than 240 g / l, preferably 200 g / l, the concentration of hydrochloric acid being increased to 7 to 8 m / l by adding concentrated sulfuric acid to the solution, in an amount equivalent to nickel present, the metallic contaminations being absorbed in an anion exchange resin, and the nickel solution and hydrochloric acid released from the effluent being separated.
