US9981295B2 Method for vitrification of arsenic and ...

Sequestring arsenic and antimony by such glass formation thus proved to be a very definitive sequestration of arsenic and antimony, and turned out to be much more economical than the formation of scorodite, which calls for the oxidation of large amounts of iron, along with As, and still requires elaborate disposal after precipitation.

How to Remove Arsenic, Antimony Bismuth from Copper

Oxidation of arsenic and antimony, and their volatilization as oxides, probably goes on during the scorification in which the two oxides combine with the cuprous oxide formed in the operation.

Arsenic | As PubChem

Arsenic "metal" is produced either by roasting the sulfide to form the oxide and then reducing the oxide with carbon or by heating arsenopyrite in the absence of air. When arsenic containing ores are smelted the arsenic becomes gaseous and burns in air to arsenic trioxide.

Experiments were carried out to remove arsenic from antimony trioxide by two techniques: first, by selectively volatilizing the more volatile arsenic trioxide from a mixed oxide sample; and, second, by selectively condensing the less volatile antimony tetroxide at high temperatures, leaving arsenic trioxide to condense out at a lower temperature.

Antimony Wikipedia

Antimony also forms a mixedvalence oxide, antimony tetroxide (Sb 2 O 4), which features both Sb(III) and Sb(V). Unlike oxides of phosphorus and arsenic, these oxides are amphoteric, do not form welldefined oxoacids, and react with acids to form antimony salts. Antimonous acid Sb(OH) 3 is unknown, but the conjugate base sodium antimonite ([Na ...

Antimony oxide (Sb2O3) | O3Sb2 PubChem

Due to the chemical affinity of arsenic and antimony, we analyzed the potency of antimony(III)oxide (Sb(2)O(3)) to exert As(2)O(3)like effects. Based on the same molar concentrations, lower efficacy in apoptosis induction and caspaseindependent decrease of mitochondrial membrane potential was observed for Sb(2)O(3).

The oxide of antimony is antimony (III) oxide which is amphoteric, meaning it can act as both an acid and a base. Antimony is obtained mainly from its sulfide ores, and it vaporizes at low temperatures. Along with arsenic, antimony is commonly used in alloys.
