Proceso para la lixiviacion de plata y cobre a partir de menas de fases minerales refractarias que contienen hierro y azufre, que comprende reduccion en un medio acido con agentes complejantes de iones sulfuros y/o ferrosos, con un agente reductor o en el compartimiento catodico de una camara electrolitica.

摘要

A method for leaching valuable metals from ore or one or more minerals that do not oxidise easily and can be reduced, comprises reducing the ore or one or more minerals in contact with an acid medium with complexing agents for sulphur and/or ferrous ions, by means of a reducing agent or in the cathode compartment of an electrolytic chamber that promotes the production of one or more mineral phases containing metals in a reduced form.
