Title:
METHOD FOR LEACHING COPPER AND SILVER CONTAINED IN REFRACTORY MINERAL PHASE ORES CONTAINING IRON AND SULPHUR
Document Type and Number:
WIPO Patent Application WO/2012/078020
Kind Code:
A3
Abstract:
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.
