Abstract

La invención se refiere al campo de la lixiviación de materias primas que contienen sulfuro de níquel con solución acuosa de cloruro de sodio y cloruro de cobre (II) para producir un producto de níquel. De conformidad con la invención, la materia prima que contiene sulfuro de níquel, como por ejemplo, un concentrado o una mena o desechos de sulfuro de níquel; se lixivia en condiciones atmosféricas con una solución acuosa de cloruro de sodio y cloruro de cobre (II). Los reactivos, como por ejemplo, cloro, hidrógeno e hidróxido de sodio, necesarios para la lixiviación del níquel y para el procesamiento de los productos se obtienen mediante la electrólisis cloro-álcali, que está integrada al proceso como un paso del mismo.The invention relates to the field of leaching raw materials containing nickel sulphide with aqueous sodium chloride solution and copper (II) chloride to produce a nickel product. In accordance with the invention, the raw material containing nickel sulfide, such as a concentrate or ore or nickel sulphide wastes; It is leached under atmospheric conditions with an aqueous solution of sodium chloride and copper (II) chloride. The reagents, such as chlorine, hydrogen and sodium hydroxide, necessary for the leaching of nickel and for the processing of the products are obtained by chloro-alkali electrolysis, which is integrated into the process as a step thereof.
