Abstract
<B>"MéTODO PARA LIXIVIAçãO DE NìQUEL A PARTIR DE ESCóRIA DE NìQUEL"<D>. A invenção se refere a um método para a lixiviação de escória sulfídica de níquel, particularmente de escória de níquel rica em cobre, assim como à lixiviação da dita escória, junto com uma escória metálica de cobre e/ou cobre/níquel. A lixívia de escória de níquel é realizada na forma de lixívia sob pressão, em um ou diversos estágios, por meio de sulfato de cobre.
