antimony ore air

The temperature must be kept low at first and the ore frequently stirred with an iron wire or spatula, to prevent fritting, and to expose fresh surfaces to the air. The roasting takes place in two stages : at first, sulphur dioxide, arsenious oxide (As2O3), and antimonious oxide (Sb2O3) are formed and volatilised, the sulphur burning with a ...

Antimony 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 is a native element that can occur in a natural state, but it is rarely pure.

Antimony compounds are prominent additives for chlorine and brominecontaining 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 leadgrey mineral, subject to black tarnish.

We understand now that the ‘lead’ described by Pliny is actually the element antimony, produced by heating its ore. (2) In the first half of the 1500s, Italian metallurgist Vannoccio Biringuccio wrote the alchemical work: “Concerning Antimony and Its Ore.” ... Exposure to 9 milligrams per cubic meter of air (mg/m 3) of antimony as ...

Estimates of the abundance of antimony in the Earth's crust range from to parts per million. 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.

Metallic antimony is not affected by air or moisture under ordinary conditions, but it is gradually converted to an oxide if the air is moist. Antimony can be oxidized easily by sulfur and the halogens when heated. When it is heated in air, it burns with a brilliant blue flame and gives off white fumes of the trioxide Sb 2 O 3. The trioxide of ...
