Antimony is a lustrous gray metalloid, it is found in nature mainly as the sulfide mineral stibnite. Antimony compounds have been known since ancient times and were powdered for use as medicine and cosmetics. The industrial methods for refining antimony are roasting and reduction with carbon or direct reduction of stibnite with iron.
Antimony smelting method has dominated and wet two kinds, mainly is sulfide ore ( stibnite), the(1) the dominated by refined antimony sulfide ore volatile roasting or volatile smelting, make Sb2S3 into Sb2O3 (known as antimony oxygen), then after reduction smelting and refining, as a metal antimony .
Oxidizing Roast; Stibnite the Antimony Mineral. The leading antimony mineral is stibnite. In smelting stibnite ore two processes are available, precipitation and roasting-reduction. The former is suited, only for high-grade ores. As low-grade ores are more common than high-grade, roasting-reduction is of greater importance than precipitation.
The invention discloses a production method of continuous antimony smelting by bottom blowing bath smelting of stibnite and a device thereof. The method comprises the steps that: stibnite, iron ore, stone and anthracite, which are taken as raw materials, are weighed and then smelted and reacted in a bottom blowing oxidization smelting furnace to generate fume and melts; the melts are settled ...

Perpetua Resources Corp. has entered into an agreement (the "Agreement") to supply a portion of antimony production from the Stibnite Gold Project to Ambri Inc. ... refining, transport, and ...
Antimony is extracted mainly from ores containing antimony trisulphide in the form of stibnite. Rich ores are first subjected to liquation, whereby the fusible sulphide is removed from the gangue and concentrated. The concentrate is then reduced to metal by smelting with wrought iron in pots, in reverberatory furnaces or sometimes in blast ...
Recovery of gold from refractory ores requires a pretreatment to liberate the gold particles from the host mineral. In particular, in the case of stibnite (Sb2S3), the antimony (Sb) forms stable ...
Transcribed image text: Problem: Antimony is obtained by heating pulverized stibnite (Sb2S3) with scrap iron and drawing off the molten antimony from the bottom of the reaction vessel: Sb2S3 + 3Fe + 2Sb + 3FeS Suppose that 0.600 kg of stibnite and 0.250 kg of iron turnings are heated together to give 0.200 kg of Sb metal. Determine a. The limiting reactant b.

The Stibnite gold project being developed by Midas Gold in central Idaho is expected to be one of the biggest and highest-grade open-pit gold mines in the US. It will also be the only primary producer of antimony in the country. The project is located in a historical mining district that had seen mining operations since 1894 with a sluice box ...
The industrial methods for refining antimony are roasting and reduction with carbon or direct reduction of stibnite with iron. What is antimony used for? Antimony is a chemical with several uses in the industry, like very pure antimony, which is used to make certain types of semiconductor devices, such as diodes and infrared detectors. ...

Antimony oxide is a white powder and is derived from the mineral stibnite (antimony sulfide) or produced by the oxidation of antimony metal or as a byproduct of the refining or antimonial-lead alloys. It sometimes behaves as a metal and sometimes as a non metal. In the glass industry small percentages of antimony oxide are used to remove ...

Antimony is sometimes found in pure form. It is also obtained from the mineral stibnite (antimony sulfide) and commonly is a by-product of lead-zinc-silver mining. Other antimony-bearing minerals include sibiconite, tetrahedrite and ullmannite. It is mined in China, Bolivia, South Africa and Mexico.
While societies from thousands of years ago used it in the form of stibnite for decoration, in modern times it is used to make semiconductor devices, batteries, low-friction metals, cable sheathing and flame-proofing materials, paint, ceramic enamels, glass and pottery. The traditional method of producing antimony metal is through heat smelting.
