Abstract:Based on the analysis of complex raw materials and the experience of production practice, the electrolytic process conditions of low arsenic anode are improved, such as reducing the current density, adjusting the amount and type of additives, changing the liquid feeding mode of electrolytic cells and controlling the proportion of anode installation. In general, through the process improvement, the phenomenon of anode passivation in the electrolysis process is eliminated, the level line particles caused by floating anode slimes are basically eliminated as well, the physical appearance of cathode copper is improved, and the normal electrolysis production of low arsenic anode has been basically realized.
