Appliion: Antimony sulfide is widely used in the war industry including gunpowder, glsss and rubber, matches, fireworks and friction materials and so on as the additive or alyst, antiblushing agent and heatstabilizer and also as the flameretardant synergist replacing antimony oxide.
antimony Definition, Symbol, Uses, & Facts Britannica
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.

Kinetic studies for sulfurfixing and roasting reduction
The author used calcium oxide as a sulfurfixing agent to fix sulfur in the form of calcium sulfide in the slag, eliminating emissions of SO 2, and then used carbon as a reducing agent, reducing Sb 2 O 3 to obtain metal antimony. This method can completely solve the pollution problem of SO 2, but the calcium sulfide and antimony product are not
Antimony is a chemical element with the symbol Sb (from Latin: stibium) and atomic number 51. A lustrous gray metalloid, it is found in nature mainly as the sulfide mineral stibnite (Sb 2 S 3). Antimony compounds have been known since ancient times and were powdered for use as medicine and cosmetics, often known by the Arabic name, kohl.

Aug 28, 2016 · New method developed for producing some metals The material they were using, antimony sulfide, is a molten semiconductor, which normally would not allow for the kind of electrolytic process that is used to produce aluminum and some other metals through the appliion of an electric current. Though the higher melting temperatures of
ANTIMONY SULFIDE presents a serious fire risk if exposed to oxidizing agents. Crystals burn with a blue flame when heated in air [Mellor 9:522 194647]. Emits toxic antimony and sulfur oxide fumes if heated to high temperatures.

Smelting and Roasting Ores to recover gold, silver and
However, this "burning" or roasting of the sulfide ores does work well to convert rebellious ores into a more free milling state, allowing the values to be extracted. Exact temperatures used in roasting vary, and excessive temperatures can cause problems, including melting the sulfides before they can oxidize.
Extraction of Antimony Element Antimony, Sb, Metalloid
The crude product contains 94 to 95 per cent, antimony mixed with iron, sulphur, lead and arsenic. This is refined by melting carefully under a flux of sodium carbonate. After a time the impurities can be skimmed off and then a mixture containing antimony oxide, antimonyl sulphide, sodium carbonate and a little coal is added.
Antimony (Sb) (atomic number 51 atomic mass 121.75 g/mol density 6.684 g/cm 3 melting point 631°C) occurs naturally as a sulphide ore, stibnite (Sb 2 S 3) and valentinite (Sb 2 0 3). The traditional method of treating the ore is to roast it with charcoal or coke and collect the volatile oxide fume (Sb 4 O 6) from which pure antimony is refined.
About Antimony Sulfide Antimony Trisulfide is a moderately water and acid soluble Antimony source for uses compatible with sulfates. Sulfate compounds are salts or esters of sulfuric acid formed by replacing one or both of the hydrogens with a metal.
