Antimony trioxide. Antimony trioxide treatment is associated with increased apoptosis associated with induced reactive oxygen species (ROS) as well as differentiation markers. When the buffering capacity of the cell is decreased by depleting glutathione, ROS production and apoptosis is enhanced. Antimony trioxide is primarily used as a flame retardant in rubber, plastics, pigments, adhesives, textiles, and paper.
This invention relates to a process forobta ining'antimony from antimony trioxide. An object of the invention is the provision of a process for obtaining antimony from the trioxide in a simple and economical manner; the . eifioacy depending upon the type of crucible, in . which the trioxide is heated.
"Crude antimony" and "crudum" are terms applied to ore that contains more than 90 percent antimony, and to liquated sulfide ore, which is essentially an antimonysulfide mixture that contains 70 percent or more antimony (Wyche, 1976). Refined antimony metal, or regulus, is the stable common form (allotrope) of antimony.
The crude product contains 94 to 95 per cent, antimony mixed with iron, sulphur, lead and arsenic. This is refined by melting carefully under a flux of sodium carbonate. After a time the impurities can be skimmed off and then a mixture containing antimony oxide, antimonyl .

Mar 01, 2014· In this process, the concentrate is roasted in a blast furnace, thereby volatilizing the resultant antimony trioxide and reducing trioxide with carbon to metallic antimony in reverberatory furnaces ( Lager and Forssberg, 1989; Tang and Jin, 2007 ).
Nov 12, 2008· Antimony trioxide itself has no flame retardant function, however, when it is used together with halogenated compounds, the synergistic effect of the mixture creates the flame retardant properties. Antimony trioxide reacts with halogenated compound and creates the chemical compounds, which generate the flame retardant function, through the following process.
Most commercial grades of antimony trioxide contain between % and % antimony trioxide with varying amounts of impurities such as arsenic, iron and lead. Commercial suppliers offer various grades of antimony trioxide based on the relative tinting strength of their product, which is .
A process for the production of antimony trioxyde comprising the steps of: (i) reacting antimony trisulfide with iron (III) chloride to produce antimony trichloride; and (ii) hydrolyzing antimony trichloride to produce antimony trioxide. In a preferred embodiment, the process is substantially closed or nearclosed loop. Antimony trioxide is a ...
Antimony trioxide Wikipedia. It is produced via two routes, revolatilizing of crude antimony(III) oxide and by oxidation of antimony metal Oxidation of antimony metal dominates in Europe Several processes for the production of crude antimony(III) oxide or metallic antimony from material The choice of process depends on the composition of the ore and other factors
The problem discussed in this antimony process study is limited to a concentrator capable of beneficiating 150 tons per day of antimony antimony in this study occurs as the mineral stibnite (Sb2S3) in association with small amounts of pyrite, arsenopyrite, galena and lead sulfantimonides.
