Research of the Process of Purification of Sulfate Zinc Solution from Iron Ions Using Anodic Oxidation

The possibility of using a membrane electrolytic cell for the electrochemical oxidation Fe(II) and purification from impurities real industrial solutions obtained by atmospheric leaching low-grade zinc concentrates is considered. average indicators carrying out electrooxidation process are given. principal conditioning sulfate solution hydrolytic with preliminary iron in an anion-exchange MA-41 TU 2255-062-05761695-2009 Carrying direct (II) anode chamber flow electrolyzer ensures good filterability precipitates after precipitation iron, since this does not contain ions, presence which leads to significant difficulties operations separating solid liquid phases. This makes it possible exclude thickening operation technological scheme. degree during test period was 99.8–99.9%. residual concentration form oxide hydroxide compounds less than 0.01 g/dm3.
