Lead smelting - Wikipedia
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 material.
