Metals are extracted from their ore through chemical reaction. Iron ore is an oxide of iron. The oxygen is removed from the ore by heating carbon with the ore to create molten iron and Carbon Dioxide.
Antimony, a metallic element belonging to the nitrogen group (Group 15 [Va] of the periodic table). Antimony exists in many allotropic forms. It is a lustrous, silvery, bluish white solid that is very brittle and has a flaky texture. It occurs chiefly as the gray sulfide mineral stibnite.
Bismuth is a chemical element with the symbol Bi and atomic number 83. It is a pentavalent post-transition metal and one of the pnictogens with chemical properties resembling its lighter homologs arsenic and antimony. Elemental bismuth may occur naturally, although its sulfide and oxide form important commercial ores.

Stibnite is the most important ore of the element antimony, and is an industrially important mineral. It was used as a metallic cosmetic in ancient civilization. Stibnite also forms some of the most exceptional crystal formations of all minerals, and large and well crystallized are highly sought after and appreciated by mineral collectors.
Mar 03, 2011· Chemical Classification: Inorganic substances . Summary: Antimony is a silvery-white metal that is found in the earth's crust. Antimony ores are mined and then mixed with other metals to form antimony alloys or combined with oxygen to form antimony oxide. Little antimony is currently mined in the United States.
Antimony is a strategic metal which is used in many industrial areas. The content of the antimony ore is the most important point for determining the area of usage.
Chemical composition of fluid inclusions, investigated by the method of triple water extractions shows the evolution of ore-forming solutions from chlorine-sodium at initial (quartz-antimonite) stage to hydrocarbonate-magnesium-calcium composition in the final (realgar-orpiment) stage of mineralization.

Antimony is stable at normal temperatures, but reacts with oxygen when heated. There are four antimony allotropes known. One of allotropes, metallic antimony, is stable, but the other three are metastable. One of the metastatic forms is explosive antimony and produces a white smoke when drawn with a metal object.It has two stable isotopes.
