  • How Is Lead Mined?

     · Lead ore comes from underground mining operations, where the lead ore seams are blasted out of the ground and transported to the surface for refinement. Lead is commonly found in deposits with other minerals, such as silver, zinc or copper. Once the lead ore is brought to the surface, it goes through a series of refining processes that separate ...

  • Lead smelting

    Lead is usually smelted in a blast furnace, using the lead sinter produced in the sintering process and coke to provide the heat source. As melting occurs, several layers form in the furnace. A combination of molten lead and slag sinks to the bottom of the furnace, with a layer of the lightest elements referred to as speiss, including arsenic and antimony floating to the top of the molten ...
