Abstract
Un proceso para la producción de ferroníquel o mata de níquel a psrtir de una solución de licor del producto que contiene por lo menos níquel, cobalto, hierro e impurezas solubles en ácido, incluyendo dichos procesos los pasos de: a) hacer entrar en contacto la solución de licor producto (7) que contiene el níquel, cobalto, hierro y las impurezas solubles en ácido con una resina de intercambio iónico (8), donde la resina absorbe selectivamente el níquel y el hierro de la solución dejando al conbalto y a las impurezas solubles en ácido en el refinado (9); b) separar el níquel y el hierro de la resina con una solución de ácido sulfúrico para producir un eluato (11) que contiene hierro y níquel; c) neutralizar el eluato para precipitar un producto de hidróxido mixto de níquel hierro (13); y d) reducir y fundir el producto de hidróxido mixto de níquel hierro para producir ferroníquel (29) o mata de níquel (24).A process for the production of ferronickel or nickel matte from a liquor solution of the product that contains at least nickel, cobalt, iron and acid soluble impurities, including such processes the steps of: a) bringing the product liquor solution (7) containing nickel, cobalt, iron and acid soluble impurities with an ion exchange resin (8), where the resin selectively absorbs the nickel and iron from the solution leaving the conbalt and impurities soluble in acid in the refining (9); b) separating the nickel and iron from the resin with a solution of sulfuric acid to produce an eluate (11) containing iron and nickel; c) neutralize the eluate to precipitate a mixed nickel iron hydroxide product (13); and d) reduce and melt the nickel iron mixed hydroxide product to produce ferronickel (29) or nickel matte (24).
