Abstract
En un método para extraer valores de níquel y cobalto de mineral laterítico conteniendo magnesio, en el cual el mineral es calcinado bajo condiciones de reducción para convertir el níquel y el cobalto al estado de metal crudo, el calcinado resultante es apagado en solución de carbonato de amonio amoniacal, se pasa gas portador de oxígeno libre a través del derretido apagado para realizar la primera etapa de lixiviación del níquel y el cobalto en el calcinado, el derretido de lixiviación de la primera etapa es espesado y se recicla la solución de lixiviación para proporcionar por lo menos parte de la solución de apagado, la mejora que comprende prolongar la primera etapa de lixiviación durante un período de tiempo más del necesario para obtener la máxima extracción de valores de níquel y de cobalto y terminar la primera etapa de lixiviación después de que la mayor parte del magnesio disuelto que es solubilizado durante el período anterior de lixiviación se ha precipitado de la solución en forma compuesta sobre los sólidos del derretido de lixiviación.In a method of extracting nickel and cobalt values from lateritic ore containing magnesium, in which the ore is calcined under reducing conditions to convert nickel and cobalt to the crude metal state, the resulting calcined is quenched in carbonate solution of ammonium ammonium, free oxygen carrier gas is passed through the quenched melt to perform the first stage of leaching nickel and cobalt in calcining, the first stage leaching melt is thickened and the leaching solution is recycled to provide at least part of the quench solution, the upgrade comprising prolonging the first stage of leaching for a period of time longer than necessary to obtain the maximum extraction of nickel and cobalt values and ending the first stage of leaching after most of the dissolved magnesium that is solubilized during the previous leaching period has precipitated out of solution in compound form on the solids of the leach melt.
