Abstract

Un metodo de recuperacion de un metal a partir de una mena de baja calidad que se somete a lixiviacion con cianuro para producir una PLS que contiene un cianuro de metal que se retira de la PLS mediante ultrafiltracion y nanofiltracion, y luego se acidifica y se sulfura para producir un sulfuro de metal del que se extrae el metal, y del que se recircula cianuro de hidrogeno a la etapa de lixiviacion con cianuro
