When pyrite is electrolyzed, Mn 2+ is oxidized into Mn 3+ at surface of anode at first. Because the Mn 3+ is a strong oxidizing agent, pyrite is easily oxidized into Fe 3+ and SO 4 2−, while Mn 3+ is reduced into Mn 2+.The reduced Mn 2+ can be oxidized into Mn 3+ at the anodic surface again. Therefore, oxidizing reaction of pyrite is carried …
