The expanded industrial experiments were conducted with practical industrial liquor to separate free alkali from sodium tungstate solution by electrolysis with cation-exchange membrane. Experimental results show that on the condition that the temperature is 50-55 ℃ and the current:density is 1000 A/m2, the single electrolysis cell is operated stably and 80% free-alkali in mass fraction is separated from the anode feed liquor of sodium tungstate, with electric ef ficiency up to more than 88% and the unit energy consumption E lower than 1900 kWh/t; while three electrolysis cells in series are operated, under the condition that the temperature is 60-65 ℃ and the current density is 1000 A/m2, the elec tric efficiency can reach higher than 88% and the unit energy consumption E can be lower than 2250 kWh/t.
