This study has been done to determine the galvanic interaction between galena and five types of grinding media (mild steel, ductile, 10% chromium, 20% chromium, and ceramic) in grinding mills, and galena-pyrite in flotation cells. The amount of Iron oxidation species derived from galvanic corrosion between galena-pyrite and the grinding medium measured by EDTA extraction. It was found that the amount of pyrite increased in a mixture of galena and pyrite, galvanic interaction between two minerals increased. The study of EDTA extraction of galvanic interaction between galena-grinding media showed the ceramic media has almost no galvanic interaction with galena, chromium media has the lowest and steel media the highest galvanic corrosion. Iron oxidation species from corrosion of grinding media measured via EDTA extraction revealed the amount of media corrosion for all grinding media are in order of mild steel > cast iron > 10% chromium > 20% chromium > ceramic media.
