In addition, magnesium ions in the electrolyte are easy to form crystals to separate out, so that pipelines are blocked, and the stable operation of the wet zinc smelting process is influenced.

Therefore, how to remove magnesium ions in the electrolyte is a common problem in the zinc hydrometallurgy and electrolytic manganese industries. The existing method for removing magnesium from electrolyte mainly comprises the steps of adding lime for neutralization, and removing magnesium in the form of magnesium hydroxide precipitate; or adding fluorine salt to form magnesium fluoride with low solubility to precipitate magnesium. The methods can reduce the concentration of magnesium ions in the electrolyte to a certain extent, and have certain advantages.
