Abstract:Application of strong acid as an additive for lead electrolysis has a significant effect in application of high-antimony lead electrolysis systems. With addition of additive of 2 g/L, it can change depletion of lead ions in electrolyte within a short period, promote concentration range of lead ions of 40%~60%, effectively improve anode passivation, indirectly improve electrolysis efficiency, obtain higher quality lead precipitation, slightly reduce direct current, and improve electrolytic lead production of 2%~5%.
