Abstract

La presente invención se relaciona con un método para recuperar valores de metales básicos a partir de minerales oxidados, mineral oxidado que incluye un primer metal elegido del grupo de níquel, cobalto y cobre. El método consiste en reducir el tamaño de las partículas del mineral a fin de que éste sea adecuado para la siguiente operación, favorecer el contacto de los elementos metálicos, poner en contacto el mineral con cloruro férrico o ferroso, hidratado o anhidro, para producir una mezcla de mineral y cloruro de hierro (II o III) sometiendo la mezcla del mineral y cloruro férrico o ferroso a suficiente energía para descomponer los cloruros en ácido clorhídrico y en óxidos de hierro del segundo grupo, formar sus respectivos cloruros, disolver selectivamente los cloruros de los metales básicos producidos, dejar el metal en forma de óxidos y en estado sólido, y recuperar los valores de los metales básicos disueltos de la solución acuosa.
