Lead processing - Lead processing - Refining: To remove and recover remaining impurities from lead bullion, either pyrometallurgical or electrolytic refining is used; the choice between the two methods is dictated by the amount of bismuth that must be eliminated from the bullion and by the availability and cost of energy. The Parkes zinc-desilvering process is the most widely used ...
Antimony is a member of group 15 of the periodic table, one of the elements called pnictogens, and has an electronegativity of 2.05. In accordance with periodic trends, it is more electronegative than tin or bismuth, and less electronegative than tellurium or arsenic.Antimony is stable in air at room temperature, but reacts with oxygen if heated to produce antimony trioxide, Sb 2 O 3.

Extraction of Antimony
Extraction of Antimony. Antimony is extracted mainly from ores containing antimony trisulphide in the form of stibnite. Rich ores are first subjected to liquation, whereby the fusible sulphide is removed from the gangue and concentrated. The concentrate is then reduced to metal by smelting with wrought iron in pots, in reverberatory furnaces or ...
Antimony | NIOSH | CDC
Antimony (Sb) is a silver-white brittle solid or a dark-gray, lustrous powder. It can be harmful to the eyes and skin. Antimony can also cause problems with the lungs, heart, and stomach. Workers may be harmed from exposure to antimony and its compounds. The level of exposure depends upon the dose, duration, and work being done.
