Abstract: PURPOSE: A feed method of chlorine gas for the oxidation of aqueous ferrous chloride solution (FeCl2) to aqueous ferric chloride solution (FeCl3) is provided, which is characterized in that injection rate of chlorine gas is changed according to FeCl2 concentration during oxidizing reaction. Therefore non-reacted chlorine gas is not discharged. CONSTITUTION: The feed rate of chlorine gas is controlled by the formula: Cmax/Wcirc ∝ Fconc, where Cmax is injection rate of chlorine gas (kg/hr), Wcirc is circulation quantity of FeCl2/FeCl3 solution and Fconc is concentration of FeCl2. Total concentration of FeCl2/FeCl3 is 0.1 to 50 wt.% and the concentration of FeCl2 is 0.1 wt.% or more. The oxidizing reaction is operated at 40 to 80 deg.C.
