PRESSURE OXIDATION OF ORE CONTAINING SILVER

摘要

A method for the treatment of sulfide ores containing silver by pressure oxidation (108). The method includes the addition of a sulfate-binding material (106) to reduce the formation of jarosite species during pressure oxidation (108). Silver can then be recovered from the solids portion of the discharge slurry (109). A jarosite reduction step, such as by a lime boil, that is typically required to recover silver after pressure oxidation (108) can be eliminated.
