Leaching process of copper and silver from refractory mineral ore containing iron and sulfur

摘要

It refers to the process of leaching silver and copper from refractory mineral phase ore containing iron and sulfur. It is characterized by that before oxidation leaching, such ore or ore containing sulfur must be reduced in acid environment, including sulfuric acid or hydrochloric acid. It contains a compound agent of sulfide and / or iron ion, a reducing agent, or is placed on the anode part of the lithium camera, in which a solid phase containing a small amount of metal and dissolved sulfide and / or iron ion is produced.
