Process for leaching Silver and Copper from ores Refractory mineral phases containing Iron and sulfur, which includes reduction in acid Medium with complexing agents of sulphides and / or ferrous ions, a reducing agent or in the cathode compartment of an electronic Camera Rolitica.

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.
