Abstract

"MéTODO PARA REDUçãO DE NìQUEL". A presente invenção se refere a um método para precipitação de níquel de sua solução aquosa como um pó de metal, usando hidrogênio. A solução aquosa contendo o composto de níquel é neutralizada inicialmente com um composto alcalino terroso ou um composto alcalino, de modo que o níquel se precipita como hidróxido de níquel ou como um sal de níquel, após o que é realizada a redução na presença de um catalisador na forma de um íon em condições atmosféricas ou condições aproximadamente atmosféricas, preferencialmente na forma de um processo contínuo.
