Abstract
<p>La presente invención describe un método para recuperar eficientemente hierro, escandio y aluminio a partir de un mineral limonítico de laterita-níquel, que comprende: triturar/ triturar finamente el mineral limonítico de laterita-níquel para obtener un polvo mineral; realizar una lixiviación selectiva del polvo de mineral con ácido nítrico para obtener un concentrado de hierro con un contenido de hierro de más del 60 porciento y sin azufre; realizar una operación controlada de precipitación / separación en la solución de lixiviación añadiendo óxido de magnesio, óxido de calcio o carbonato de calcio para obtener una mezcla de aluminio y escandio; luego deshidratar la mezcla de aluminio y escandio por tostado, mezclando posteriormente una cantidad apropiada de criolita y realizando una electrólisis de sal fundida para producir directamente una aleación de aluminio y escandio; neutralizando la solución obtenida después de la precipitación controlada / separación para producir un producto de hidróxido de níquel-cobalto, o realizando una extracción electrolítica de extracción en la solución para producir un producto de níquel-cobalto. La presente invención puede garantizar una lixiviación selectiva de níquel y cobalto mientras se logra un reciclado eficiente de hierro, escandio y aluminio en condiciones suaves sin presurización externa. Las tasas de lixiviación para el níquel y el cobalto pueden alcanzar el 90 porciento o más. Las recuperaciones de hierroy escandio pueden alcanzar el 95 porciento o más, y la recuperación de aluminio puede alcanzarel 65 porciento. Por lo tanto, la presente invención puede lograr una recuperación y utilización eficientes de hierro, escandio, aluminio, níquel y cobalto en el mineral limonítico de laterita-níquel.</p><p> The present invention describes a method for efficiently recovering iron, scandium and aluminum from a laterite-nickel limonitic mineral, comprising: grinding / finely grinding the laterite-nickel limonitic mineral to obtain a mineral powder; perform a selective leaching of the mineral dust with nitric acid to obtain an iron concentrate with an iron content of more than 60 percent and without sulfur; performing a controlled precipitation / separation operation in the leaching solution by adding magnesium oxide, calcium oxide or calcium carbonate to obtain a mixture of aluminum and scandium; then dehydrating the mixture of aluminum and scandium by roasting, subsequently mixing an appropriate amount of cryolite and performing a molten salt electrolysis to directly produce an alloy of aluminum and scandium; by neutralizing the solution obtained after controlled precipitation / separation to produce a nickel-cobalt hydroxide product, or by performing an extraction electrowinning on the solution to produce a nickel-cobalt product. The present invention can ensure selective nickel and cobalt leaching while achieving efficient recycling of iron, scandium and aluminum under mild conditions without external pressurization. Leaching rates for nickel and cobalt can reach 90 percent or more. Iron and scandium recoveries can reach 95 percent or more, and aluminum recovery can reach 65 percent. Therefore, the present invention can achieve efficient recovery and utilization of iron, scandium, aluminum, nickel, and cobalt in laterite-nickel limonitic ore. </p>
