Antimony Ore To Antimony Oxide

ANTIMONY OXIDE LISTING BACKGROUND - US EPA

Antimony oxide can be prepared by two processes, the direct and the indirect process. Indirect process. In this process, antimony metal or ores is melted in a furnace to give ATO vapors. The vapors are quenched with air and cooled to convert the vapor to white powder. These powders are further filtered to give antimony trioxide powder.

The additional presence of antimony oxide, in Cr/Sb 1/1.6 and 1/2.8 samples, further improves the selectivity to acrylonitrile, with a decrease in CO 2 formation. Cr/V/Sb/O catalysts. Cr/V/Sb/O catalysts were prepared having different atomic ratios between components: Cr/V/Sb l/x/δ (with x between 0 and 1.3, and δ approximately equal to 2).

ATSDR - Toxic Substances - Antimony

Antimony is a silvery-white metal that is found in the earth's crust. Antimony ores are mined and then either changed to antimony metal or combined with oxygen to form antimony oxide. (1) Antimony trioxide is a white powder that is very slightly soluble in water. (1) Antimony metal is a very brittle, moderately hard metal. (1)

ANTIMONY OXIDE LISTING BACKGROUND - US EPA

On combustion at a temperature of over 600 0 F, the halogen forms hydrochloric or hydrobromic acid that reacts with the antimony oxide to form antimony trichloride, antimony oxychloride, antimony tribromide, or antimony oxybromide. The flame retarding action takes place in the vapor stage above the burning material.

Antimony: Chemical reactions | Pilgaard Elements

Feb 08, 2016· Antimony has become an increasingly critical element in recent years, due to a surge in industrial demand and the Chinese domination of primary production. Antimony is produced from stibnite ore (Sb2O3) which is processed into antimony metal and antimony oxide (Sb2O3). The industrial importance of antimony is mainly derived from its use as flame retardant in plastics, coatings, and …

processing technology for antimony oxide ores - Minevik

The extraction of antimony from ores depends on the quality of the ore and composition of the ore. Most antimony is mined as the sulfide; lower grade ores are concentrated by froth flotation, while higher grade ores are heated to 500–600°C, the temperature at which stibnite melts and …
