6 FAQs about [Lead smelting technology of old batteries]

What is lead smelting?

Overall, lead smelting is a critical process in the lead battery recycling plant, allowing for the extraction of lead from used batteries and the recycling of this lead for use in new batteries or other industrial applications.

How long does a lead smelting process take?

During the smelting process, impurities in the lead material are separated from the lead and removed from the furnace. This process can take several hours or even days, depending on the quantity and quality of the materials being smelted. The resulting lead is then refined and purified, typically through a process called electrolysis.

How do you smelt lead?

The lead plates and lead oxide paste are then smelted in a furnace to extract the lead.
