Abstract

Procedimiento para la producción de níquel de alta pureza, a partir de minerales niquelíferos, caracterizado por el hecho de que se compone, en la sucesión, de las siguientes etapas: a) fraccionamiento, luego tostadura del mineral niquelífero de partida, a una temperatura del orden de los 9000 grados C., con producción de óxido de níquel; b) ataque de este óxido de níquel impuro mediante ácido clorhídrico concentrado; c) oxidación al estado férrico del hierro contenido dentro de la solución impura que resulta de la etapa precedente; d) eliminación de las impurezas de esta solución por medio de resinas intercambiadoras de iones; e) electrólisis de la solución así purificadaProcedure for the production of high purity nickel from nickel-bearing minerals, characterized by the fact that it consists, in succession, of the following stages: a) fractionation, then roasting of the starting nickel-bearing mineral, at a temperature of order of 9000 degrees C., with production of nickel oxide; b) attack of this impure nickel oxide by concentrated hydrochloric acid; c) oxidation to the ferric state of the iron contained within the impure solution resulting from the preceding stage; d) removal of impurities from this solution by means of ion exchange resins; e) electrolysis of the solution thus purified
