Description

Wet discharge type slurry electrolytic lead device

technical field

The utility model relates to a wet discharge type ore pulp electrolysis lead device, which is especially suitable for electrolysis of ore pulp.

Background technique

The electrolytic cell is the key equipment supporting the electrolysis industry of lead, zinc, manganese, aluminum and other metals. However, most of the existing electrolytic cells can only electrolyze the solution, but not the electrolytic slurry. That is, the electrolytic solution must be prepared before electrolysis. .

The preparation of mineral powder into electrolyte requires multiple steps such as compounding, dissolution, pressure filtration and impurity removal. The cost of many steps is high, and there is still a certain loss in the preparation process. If the mineral powder can be directly made into slurry in the electrolytic cell Electrolysis can greatly simplify the process, reduce intermediate links, save costs and increase product yield.

The essence of slurry electrolysis is to add mineral powder and corresponding acid into the electrolytic tank, and then directly carry out the electrolysis operation after the combination reaction of mineral powder and acid, that is, the combination and electrolysis are carried out at the same time. The advantage of this operation is that it can greatly simplify the process. Combination, impurity removal, and electrolysis are completed in the tank together, omitting pressure filtration and other processes, saving costs and reducing a lot of liquid storage tanks, and at the same time, a large amount of sulfuric acid produced by electrolysis anodes can continuously react with mineral powder to make mineral powder The lead in the electrolytic solution is continuously dissolved in the form of ions, which promotes the obtaining of higher quality and yield of electrolytic lead.

For electrolytic lead, slurry electrolysis can effectively simplify the hydrometallurgical process and reduce costs. However, lead ore slurry electrolysis faces many difficulties in industrial application, such as achieving stable slurry suspension electrolysis and ion concentration in the entire long electrolytic cell. Uniform distribution, liquid circulation between slurry reaction zone and electrolysis zone, discharge of deposited sponge lead, etc. These unresolved technical problems directly affect the application and development of slurry lead electrolysis technology.
