Firstly, mounting a cathode assembly and an anode assembly in a suspension electrolytic tank, placing cathode plates 32 in a diaphragm bag 42 to form that the cathode plates 32 and the anode plates 31 are uniformly and alternately distributed in a tank body 1 of the electrolytic tank; pulping lead concentrate and electrolyte (40 g/L hydrochloric acid, 100 g/L-150 g/L sodium chloride/calcium chloride and 40 g/L-60 g/L lead) in a pulping tank, transferring the slurry into a suspension electrolytic tank through a pump, electrifying for electrolysis, oxidizing and dissolving lead concentrate pulp in an anode area, allowing lead ions to enter the electrolyte, and separating out lead ions in the electrolyte on a cathode plate 32 in a diaphragm bag 42; discharging ore pulp after the electrolysis is finished, returning filtered liquid to a slurrying system for recycling, and discharging filter residues for flotation to recover sulfur and rare and precious metals; and taking out the cathode plate 32, cleaning and stripping to obtain the cathode lead.
Application scenario two: the application of the suspension electrolytic cell in waste circuit board pulp electrolysis is further explained by taking waste circuit board pulp electrolysis as an example. Firstly, mounting cathode and anode components in a suspension electrolytic cell, placing cathode plates 32 in a diaphragm bag to form that the cathode plates 32 and the anode plates 31 are uniformly and alternately distributed in an electrolytic cell body 1; the waste circuit board scraps and electrolyte (20-100 g/L sulfuric acid and 20-60 g/L copper) are pulped in a pulping tank, the pulp is transferred into a suspension electrolytic tank through a pump, and electrolysis is carried out by electrifying. Copper in the waste circuit board is oxidized and dissolved in the anode area, copper ions enter the electrolyte, and the copper ions in the electrolyte are separated out on the cathode plate 32 in the diaphragm bag 42; discharging ore pulp after the electrolysis is finished, returning filtered liquid to a slurrying system for recycling, and discharging filter residues to recycle waste plastic scraps and metals such as tin, silver, gold and the like; taking out the cathode plate 32, and obtaining cathode copper through cleaning and stripping.
Application scenario three: the application of the suspension cell to the purification of low-metal solutions is further illustrated by taking the electrowinning depletion of copper-containing solutions as an example. Firstly, mounting a cathode-anode assembly in a suspension electrolytic tank, placing an anode plate 31 in a diaphragm bag 42 to form that the anode plate 31 and a cathode plate 32 are uniformly and alternately distributed on the tank body; pumping the copper-containing solution into a suspension electrolytic tank, simultaneously supplementing a certain amount of copper powder, and electrifying for electrolysis.

And an application scene four: for the electrolytic conversion of the slightly soluble/insoluble system, the electrolytic conversion of lead-containing materials such as lead sulfate, waste lead plaster and the like in a dilute sulfuric acid system is taken as an example, and the related application of the suspension electrolytic cell in the direct conversion of the slightly soluble/insoluble system is further explained. Firstly, mounting a cathode-anode assembly in a suspension electrolytic tank, placing an anode plate 31 in a diaphragm bag 42 to form anode plates 31 and cathode plates 32 which are uniformly and alternately distributed on the tank body; and pulping the lead sulfate slag and the waste lead paste by using a pulping tank, pumping the pulped lead sulfate slag and the waste lead paste into a suspension electrolytic tank, and electrifying to perform electrolytic conversion. Under the action of stirring, the cathode plate 32 collides with insoluble substances such as lead sulfate, lead oxide, lead dioxide and the like, so that the lead sulfate, the lead oxide, the lead dioxide and the like are promoted to obtain electrons and are reduced into metallic lead, and oxygen is separated out from the anode in the diaphragm bag 42; and discharging the slurry after the electrolytic conversion is finished, filtering to obtain sponge lead powder and filtrate, returning most of dilute sulfuric acid electrolyte (10-50 g/L sulfuric acid) to the slurrying system for recycling, and performing partial open-circuit purification treatment to obtain dilute sulfuric acid generated in the open-circuit lead sulfate conversion process.
