Method for recycling metal lead from waste lead plaster by using ore pulp electrolysis technology

The invention discloses a method for recovering metal lead from waste lead plaster by using an ore pulp electrolysis technology, which adopts a chlorine salt ore pulp electrolysis system to simultaneously realize leaching and electro-deposition of Pb in the waste lead plaster so as to recover the metal lead. The selected electrolyte system comprises HCl, NaCl and PbCl2, and the HCl can be used as an acid medium, can directly dissolve PbO2 and can also provide a ligand Cl , so that the effects of accelerating the electromigration rate of ions in the solution, reducing the resistance and improving the recovery efficiency of lead are achieved. According to the method, leaching and electro-deposition of Pb in the waste lead paste can be carried out in the same device at the same time, the method is a short-process new technology, energy consumption can be reduced, and a metal lead product can be obtained. 本发明公开了一种利用矿浆电解技术从废铅膏中回收金属铅的方法，采用氯盐矿浆电解体系，同时实现废铅膏中Pb的浸出和电沉积，以回收金属铅。本发明所选电解液体系包含HCl、NaCl、PbCl2，其中HCl既可以作酸性介质
