The development of a process for the extraction of antimony from materials produced by Greenbushes Tin Limited has been carried out based on theoretical and laboratory studies. The materials treated have included concentrates of tantalite and cassiterite containing antimony at levels ranging from 0.3% to 2%. Roasting under controlled atmospheres is required to stabilise Sb203...
Nov 14, 2018· While Backeberg doesn't think the project is going to 'rock the boat' for the antimony market because it is only an intermediary step, it does, however, offer a significant supply of non-Chinese antimony products. "The problem is it needs to find supply for the roaster to operate," says Backeberg.
Fume generated by roasting speiss is contacted with an oxygen-containing gas at an elevated temperature for a sufficient time to produce arsenic and antimony products which may be separated from each other by means such as condensation. Further, in the roasting of antimony-containing phases (such as speiss) the presence of arsenic can enhance the volatility of the antimony.

Antimony is often found in other ores as well, e.g., silver, copper, and lead. The pure element antimony is produced from the ore by roasting it to form the oxide, then reducing the oxide with carbon or iron; often a flux of sodium sulfate or sodium carbonate is used to prevent loss of molten antimony …

) is an abundant antimony bearing mineral and thus it is the main source for the production of pure antimony trioxide and/or metallic antimony. The conventional technology for the production of metallic antimony from stibnite concentrates is primarily by oxidizing roasting to convert the stibnite into volatile antimony oxide (Sb 2 O 3
In some cases, partial roasting is used to remove almost all unwanted elements – such as arsenic and antimony – before further treating the calcine. Special equipment is used for cooling and precipitating arsenic trioxide, which can be produced to a very high purity. Most of our sulfating roasting …
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. Metallic antimony was also known, but it was …
