Antimony(III) oxide has suspected carcinogenic potential for humans. Its TLV is 0.5 mg/m 3, as for most antimony compounds. No other human health hazards were identified for antimony(III) oxide, and no risks to human health and the environment were identified from the production and use of antimony trioxide in daily life.

Antimony is a lustrous silverywhite semimetal or metalloid. Archaeological and historical studies indie that antimony and its mineral sulfides have been used by humans for at least six millennia. The alchemist Basil Valentine is sometimes credited with "discovering" the element he described the extraction of metallic antimony from stibnite in his treatise "The Triumphal Chariot of
Antimony is an important mineral commodity used widely in modern industrialized societies. The element imparts strength, hardness, and corrosion resistance to alloys that are used in many areas of industry, including in leadacid storage batteries. Antimony''s leading use is as a fire retardant in safety equipment and in goods, such as mattresses.
The early use of antimony sulfide (Sb 2 S 3) has been recorded in an Egyptian papyrus dating back to 1600 BC . Its mineral ore, stibnite, was commonly used in its black form as mascara by the ancient people notably by the temptress Jezebel . Lead antimonate, a yellowish pigment was used by the Chaldean craftsmen during 600500 BC .
Antimony Simple English Wikipedia, the free encyclopedia
Stibnite is the main ore of antimony. China is the biggest maker of antimony it makes 84% of all antimony. Other countries that make antimony are South Africa, Bolivia, and Tajikistan. Antimony is not used in the human body. Production. Antimony is made from stibnite by heating it with air. This makes antimony trioxide.
What Are Some Different Types of Ores and Their Uses
Some different types of ores and their uses are bauxite, which contains aluminum stibnite, which contains antimony chromite, which supplies chromium chalcopyrite, which provides copper and wolframite and scheelite, which provide tungsten. Each ore can have metals extracted for use in construction, electrical items and other goods.
Antimony alloys are also used in batteries, low friction metals, type metal and cable sheathing, among other products. Antimony compounds are used to make flameproofing materials, paints, ceramic enamels, glass and pottery. The ancient Egyptians used antimony, in the form of stibnite, for black eye makeup.

Antimony is a minor ore of the element antimony, although most antimony comes from antimony compounds (namely Stibnite), which are much greater in abundance. Antimony has a very interesting property: It is similar to water, in that instead of contracting when it solidifies, like all other matter, it expands.
The problem discussed in this antimony process study is limited to a concentrator capable of beneficiating 150 tons per day of antimony ore.The antimony in this study occurs as the mineral stibnite (Sb2S3) in association with small amounts of pyrite, arsenopyrite, galena and lead sulfantimonides. The gangue is composed largely of quartz but contains, in addition, a small amount of talc.

Antimony is also used as an alloy in solder. Highly purified antimony is used in semiconductor technology to prepare the intermetallic compounds indium, aluminum, and gallium antimonide for diodes and infrared detectors. Antimony compounds (especially the trioxide) are widely used as flame retardants in paints, plastics, rubber, and textiles.
Antimony is chalcophile, occurring with sulfur and the heavy metals, lead, copper, and silver. Over a hundred minerals of antimony are found in nature. Stibnite (Sb 2 S 3) is the predominant ore mineral of antimony. The most important use of antimony metal is as a hardener in lead for storage batteries.
But pharmaceutical uses of antimony have a long history. In the ancient world it was known primarily in the form of its black sulphide ore, called stibnite, which the Greek physician Dioscorides recommended for skin complaints in the first century AD. The Egyptians, meanwhile, used stibnite as a cosmetic, applying it as a form of mascara.
