Antimony compounds are prominent additives for chlorine- and bromine-containing fire retardants found in many commercial and domestic products. An emerging application is the use of antimony in microelectronics. Shipment/storage. Ore concentrate or residue of the element antimony. A high density lead-grey mineral, subject to black tarnish.
· Antimony is a naturally occurring metal typically found in ore deposits.  Antimony is widely used in industry and present in all kinds of everyday itemsMost commonly, the metal has been used as a flame retardant in products as diverse as toys, car seat covers, engine covers for light aircraft, clothing for kids, and uniforms for fire fighters.
A native element, antimony metal is extracted from stibnite and other minerals. Antimony is used as a hardening alloy for lead, especially storage batteries and cable sheaths, also used in bearing metal, type metal, solder, collapsible tubes and foil, sheet and pipes, and semiconductor technology. Stibnite is the most important ore for antimony.
An alloy with lead greatly improves strength and hardness of lead. It also is used in semiconductors, diodes, infrared detectors, batteries and bullets. Antimony compounds are used in paint pigments, enamels, glass, and pottery.
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.

Our group has completed mines exploitation, abroad import; offshore investments for mines exploitation, establishment of mine selecting factory overseas ...
Antimony also is used as an alloy, as it hardens other metals. An alloy with lead greatly improves strength and hardness of lead. It also is used in semiconductors, diodes, infrared detectors, batteries and bullets. Antimony compounds are used in paint pigments, enamels, glass, and pottery.
· 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.

Uses of Antimony. The major use of antimony is in lead alloys – mainly for use in batteries – adding hardness and smoothness of finish. The higher the proportion of antimony in the alloy, the harder and more brittle it will be. Alloys made with antimony expand on cooling, retaining the finer details of molds.

Mining of antimony ore has been limited to northern Sevier County, although some stibnite is also present in Pike County, associated with cinnabar (HgS). Mined ore deposits occurred as lenses or pockets of stibnite encased in nearly vertical quartz veins. Antimony mining took place intermittently in Arkansas after the metal's discovery in 1873.
Cyanidation of gold ores containing copper, silver, lead .... Abstract Cyanidation tests on two ore samples from two different gold deposits are reported. The first sample contained 10.5 ppm gold with high arsenic and antimony.The second sample had a low gold content (2.5 ...
Lead processing, preparation of the ore for use in various products.. Lead (Pb) is one of the oldest metals known, being one of seven metals used in the ancient world (the others are gold, silver, copper, iron, tin, and mercury).
Antimony Ore any of the natural mineral formations containing antimony in compounds and concentrations that make commercial use technically and economically feasible. Of the antimony ores proper, the major mineral is antimonite (Sb2S3), which contains up to 71.4 percent Sb; in rare cases, antimony ores are represented by complex sulfides of antimony ...

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.
Antimony and antimony alloys are a great way to harden other metals by melting and mixing them in. Remember Antimony melts at over 1100 F, so if your looking to harden up a lead alloy you already have, try our Super Hard alloy that easily blends in at only 750 F.
The largest applications for metallic antimony is an alloy with lead and tin and the lead antimony plates in lead–acid batteries. Alloys of lead and tin with antimony have improved properties for solders, bullets, and plain bearings .
Antimony is a metalloid. A metalloid is an element that has characteristics of both metals and non-metals. The metalloids can be found on either side of the staircase line on the right side of the periodic table (with the exception of aluminum, which is not considered a metalloid).. Antimony is primarily used in alloys, ceramics and glass, plastics, and flame retardant materials.
