Abstract
La invención se refiere a un método para el procesamiento de minerales de laterita, para que los metales contenidos en las lateritas se convierten en formas solubles en agua para la recuperación de metales valiosos, como el níquel y el cobalto. Los diferentes tipos de lateritas de níquel se procesan al mismo tiempo, sin separarse de acuerdo con su contenido de hierro y/o magnesio. Cuando las lateritas son pretratadas con ácido mineral concentrado de manera que los metales contenidos en las lateritas reaccionen para formar sales solubles en agua, los silicatos contenidos en las lateritas son parcialmente descompuestos y la separación líquido-sólido posterior a la lixiviación se hace más fácil de lo que era antes. De acuerdo con el método, el vapor de agua generado en la etapa de la reacción del ácido y el mineral se utiliza en el secado del mineral y el ácido mineral que no ha reaccionado se recicla a la parte inicial del proceso.The invention relates to a method for the processing of laterite minerals, so that the metals contained in the laterites are converted into water soluble forms for the recovery of valuable metals, such as nickel and cobalt. The different types of nickel laterites are processed at the same time, without separating according to their iron and / or magnesium content. When the laterites are pretreated with concentrated mineral acid so that the metals contained in the laterites react to form water soluble salts, the silicates contained in the laterites are partially decomposed and the liquid-solid separation after leaching becomes easier. what it was before. According to the method, the water vapor generated in the reaction stage of the acid and the mineral is used in the drying of the mineral and the unreacted mineral acid is recycled to the initial part of the process.
