Production Process Of Antimony Trioxide From Antimony Concentrate Powder. 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 The chemical symbol ...An improved process for refining lead bullion containing antimony, in which the bullion is initially heated in a refining vessel to about 25° F. (14° C.) above the bullion melting point, and is thereafter kept molten primarily by exothermic process reactions. The process includes the steps of melting the lead-antimony bullion, agitating the ...
Sep 01, 2021 Tang and Jin (2007) have studied the production of antimony trioxide from antimony concentrate bearing high copper by pyrochemical process (1150–1350 C) in a blast furnace, wherein the formation of antimony trioxide was facilitated through volatilization.The invention discloses a production device for large-particle-size antimony trioxide. The production device comprises an antimony white furnace (1), an air cooled type reactor (3), a crystallizer (6) and a cooling dust collector (5), wherein the cooling dust collector (5) is communicated with an air outlet above the crystallizer (6). The production device is …
1.3 Production and use Antimony is produced from minerals. The most important mineral source of the metal is stibnite (antimony trisulfide), but it is also found in trace amounts in silver, copper and lead ores (EU-RAR 2008). Antimony trioxide is obtained by roasting stibnite ores (Sb 2 S 3) which are reported to contain 55% antimony (IARC 1989).Chronic exposure to antimony trioxide and/or pentoxide dust 8.87 mg antimony/m 3 or greater was seen to cause pneumoconiosis however these workers were also exposed to a variety of other compounds like arsenic oxide iron oxide hydrogen sulfide and sodium hydroxide 9 10 .Antimony pneumoconiosis was also described by Karajovic in a
