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 is lead used to make batteries?

The resulting lead is then refined and purified, typically through a process called electrolysis. This involves passing an electric current through the lead to remove any remaining impurities. Once the lead has been extracted from the batteries and refined, it can be used to manufacture new batteries or other lead-based products.
