Purification and recycling of lead from used batteries

One of our solutions in Amin Selfchegan to reduce the price of the final product of pure lead ingots is to recycle used car batteries and extract lead from them. With this work, we contribute to the reduction of environmental pollution caused by lead mining in mines and help to reduce vehicle waste.

It is interesting to know that about 70% of the weight of the used battery can be reused and purified and lead extracted and this cycle can be repeated many times. The final product from this process is also very high quality and with a high purity percentage and guaranteed but at a much lower price, it is available to customers and industries.

In general, battery shredding and pulp recycling systems operate based on the following two processes:

The process of chemical recycling of lead after mechanical crushing of used batteries
Electrochemical recycling process of lead after mechanical crushing of used battery

Preparation of battery paste

The input of lead purification process from used battery includes all wet and dry or atomic car batteries. The output of this process is the production of pulp containing polypropylene sulfate, metal lead, ebonite, polyvinyl chloride and other separators and sodium sulfate solution.

Other purification steps include pulp separation, hydrodynamic separator with upward flow, pulp desulfurization and production of crystallized sodium sulfate.

After this stage, lead is extracted from the final product and obtained in the form of impure lead ingots. In the final phase, this product turns into a pure lead ingot with a guaranteed high purity percentage.
