Sep 15, 2018· Abstract. Antimony is a semi metallic chemical element in Period 5 and Group 15 of the Periodic Table of chemical elements. Because it is semi metallic, it exists as both a metal and non-metal.
Bioaccumulation of Antimony and Arsenic in Vegetables and Health . Sep 9, 2015 . XKS Sb mine, known as the "World's Antimony Capital," is located in . The ores are simple in composition, with stibnite as the ore mineral.
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.
Jul 12, 2013· Antimony occurs naturally in the environment and is predominantly found in Russia, Bolivia, china, and South Africa. It is found in over 100 mineral species with sulfide stibnite (Sb 2 S 3) being the main ore mineral. Chemical Properties. The chemical properties of antimony .

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.
Table 1 shows the chemical composition of gold ores determined by mineralogical analysis and X-ray fluorescence. The ore mainly contained 39.72% SiO 2, 23.34% FeS 2, 1.96% Sb and 24 g/t Au. The sodium sulfide and sodium hydroxide used in this experiment are all analytically pure.
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.
Composition, Structure and Associated Minerals: Stibnite is the commonest and the most important ore of antimony. As found, however, it usually contains small quantities of iron and often traces of silver and gold. Surfaces that are exposed to the air are often coated with a black or an iridescent tarnish. It is a nonconductor of electricity.

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.
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.
Mineral - Mineral - Classification of minerals: Since the middle of the 19th century, minerals have been classified on the basis of their chemical composition. Under this scheme, they are divided into classes according to their dominant anion or anionic group (e.g., halides, oxides, and sulfides).
Antimony Ore any of the natural mineral formations containing antimony in compounds and concentrations that make commercial use technically and economically feasible.
