Introduction. In electrolytic manganese industry, the concentration of manganese (Mn 2+), which is the major component in electrolytes, is of great concern.The Mn 2+ concentration can be neither too high nor too low during processes. In newly prepared purified leachate, the Mn 2+ concentration should be 34.0~38.0 g/L, while that …
