ELECTROLYZING METHOD FOR REMOVING ARSENIC

PURPOSE:To remove efficiently impurities from a copper electrolytic soln. used in the electrolytic refining of copper by allowing SO2 to be absorbed in the electrolytic soln. and purifying the soln. by electrolysis in an electrolytic cell for removing arsenic. CONSTITUTION:When an electrolytic soln....

Zusammenfassung:	PURPOSE:To remove efficiently impurities from a copper electrolytic soln. used in the electrolytic refining of copper by allowing SO2 to be absorbed in the electrolytic soln. and purifying the soln. by electrolysis in an electrolytic cell for removing arsenic. CONSTITUTION:When an electrolytic soln. drawn from an electrolytic cell for electrolytically refining copper is purified in an electrolytic cell for removing arsenic, SO2 is allowed to be absorbed in the electrolytic soln. to reduce most of quinquevlent impurities to tervalent ones before the soln. is introduced into the electrolytic cell for removing arsenic. The amount of SO2 absorbed is regulated to about 0.5-6.5g/l. Thus, electrolysis for removing arsenic is carried out rapidly and efficiently.
