Plants for the production of lead are generally referred to as lead smelters. Primary lead The crude bullion and lead slag layers flow out of the furnace front and into the forehearth, where the two streams are separated. Dross refers to the lead oxides, copper, antimony and other elements that float to the top of the lead.
The prominent exposures of concern are to silica dusts, metal fumes, sulfur and ground ore, containing 3-8% lead, is concentrated by differential flotation. Metallic lead is formed in the blast furnace and separated from slag by gravity.

Nonferrous slags are produced during the recovery and processing of series of devices including cyclone separators, inclined vibratory tables, and flotation tanks. General process diagram for copper, nickel and lead-zinc slag production.
The primary end users of lead are batteries and ammunition. Finally, a layer of blast furnace slag, which contains mostly silicates, also forms. Dross refers to the lead oxides, copper, antimony and other elements that float to the top of the
At the end of the flotation process, the lead has been separated from the rock, the lead and other metal oxides, producing molten lead, nonmetallic waste slag,
