Jan 13, 2003· Antimony was (Sb) not known when antimony was first discovered, although it was known to exist in compounds by ancient civilisations. It was known to exist is metallic form in the 17 th century and possibly even earlier. Antimony and several of its compounds are .
Copper, Lead and Zinc Smelting and Refining
During the fourth step, the lead bullion is refined using pyrometallurgical methods to remove any remaining nonlead saleable materials (, gold, silver, bismuth, zinc, and metal oxides such as antimony, arsenic, tin and copper oxide). The lead is refined in a cast iron kettle by five stages. Antimony, tin and arsenic are removed first.

Antimony Properties and reactions |
Antimony Antimony Properties and reactions: The most stable form of elemental antimony is a brittle, silvery solid of high metallic lustre. Electrolytic deposition of antimony under certain conditions produces an unstable, amorphous form called "explosive antimony," because, when bent or scratched, it will change in a mildly explosive manner to the more stable, metallic form.

When pyrometallurgical methods of refining are used, bismuth is removed by adding a calcium–magnesium alloy to the molten lead, causing a quaternary alloy of lead–calcium–magnesium–bismuth to rise to the top of the melt where it can be skimmed off (Lead Development Association International, 2003c).
Pagrik Ethiopia::Remelted Lead Ingots
Dross refers to the lead oxides, copper, antimony and other elements that float to the top of the lead. Dross is usually skimmed off and sent to a dross furnace to recover the nonlead components. The molten lead is further refined in the refining kettle using pyrometallurgical methods to produce % of Pure Lead and specific lead alloys.
