Abstract

Un proceso para el tratamiento de un mineral de níquel laterítico/ cobalto que consiste en una mezcla (2) de limonita y saprolita, caracterizado porque la mezcla (2) en la presencia de un agente de precipitación de hierro se convierte en una pulpa (1), que tiene un contenido de sólidos de entre el 10% y el 40% en peso, la pulpa pasa por una operación de lixiviación (4) con ácido sulfúrico (5), a una temperatura de entre 70°C y el punto de ebullición y a presión atmosférica; y se realiza una separación de sólido y líquido (8) de manera tal que se obtenga un residuo sólido que contienen hierro (9) y una solución que contiene iones de níquel y cobalto. Un proceso para producir concentrados intermedios de níquel y/o cobalto o productos comerciales usando el proceso precedente.A process for the treatment of a lateritic nickel / cobalt mineral consisting of a mixture (2) of limonite and saprolite, characterized in that the mixture (2) in the presence of an iron precipitation agent is converted into a pulp (1 ), which has a solids content of between 10% and 40% by weight, the pulp goes through a leaching operation (4) with sulfuric acid (5), at a temperature between 70 ° C and the point of boiling and atmospheric pressure; and a separation of solid and liquid (8) is performed such that a solid residue containing iron (9) and a solution containing nickel and cobalt ions are obtained. A process for producing intermediate nickel and / or cobalt concentrates or commercial products using the preceding process.
