The method for removing lead in a nickel mixed acid system solution involves a method for removing lead from a nickel electrolytic mixed acid system solution by using a lead carbonate removing process. It is characterized in that the lead removal process is the addition of barium carbonate to the nickel mixed acid system solution for precipitation and lead removal.
The invention uses the lead impurity element in the solution of the nickel electrolysis mixed acid system to remove the lead and purify the solution, thereby reducing the lead removal load in the purification process, stabilizing and improving the solution quality. The use of mechanical stirring paddle, so that the slurry is mixed evenly to ensure adequate response, lead removal effect is obvious; barium carbonate lead removal process using less equipment, small footprint, simple process, no pollution of the operating environment.
