antimony ore to antimony oxide

Mar 03 2011 · Antimony is a silverywhite metal that is found in the earths crust Antimony ores are mined and then mixed with other metals to form antimony alloys or combined with oxygen to form antimony oxide Little antimony is currently mined in the United States It is brought into this country from other countries for processing

USAC ANTIMONY OXIDE TYPES LOW TINT ANTIMONY OXIDE LT L T is a mixture of senarmontite and typically more than 3 valentinite with an average particle size of 18 to 30 microns It is used where a low tint strength is desirable to reduce the cost of pigments LOW DUST ANTIMONY OXIDE PRODUCTS

Antimony can be isolated from the crude antimony sulfide by a reduction with scrap iron The sulfide is converted to an oxide and advantage is often taken of the volatility of antimony oxide which is recovered from roasting This material is often used directly for the main applications impurities being arsenic and sulfide Isolating antimony from its oxide is performed by a carbothermal reduction Antimony is a

AntimonyIII oxide is an amphoteric oxide it dissolves in aqueous sodium hydroxide solution to give the metaantimonite NaSbO 2 which can be isolated as the trihydrate AntimonyIII oxide also dissolves in concentrated mineral acids to give the corresponding

Antimony is a silverywhite metal that is found in the earths 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

Density of antimony oxide or antimony sulfide is much bigger than that of gangue so for most all antimony ores gravity separation can work well with good beneficiation efficiency Even though in some situation gravity separation can not help to get qualified concentrate it can save lots of investment and operation cost as preseparation

The volatilisation and oxidation of antimony trisulphide have been studied in detail From the results it is suggested that rich or concentrated ores which do not contain precious metals arsenic or lead should be roasted to antimony tetroxide while poorer ores and ores containing precious metals should be roasted to antimony trioxide

Antimony oxide sulfide Antimony oxide sulfide was synthetically made in 1842 by roasting antimony ores Depending on oxidation conditions the pigment can range in hue from orange antimony trisulfide to deep red antimony vermillion It is an unstable crystalline form and turns black when mixed with lead pigments Get price

In 1981 1700 tonnes of ore was being mined each day which was between 2 and 3 percent pure antimony Reserves In 1981 reserves at the Xikuangshan deposit amounted to 10000000 tonnes of ore that contained 2 to 3 percent antimony 200300000 tonnes of antimony at the time geologists thought that there may be more in the area

Antimony Ore any of the natural mineral formations containing antimony in compounds and concentrations that make commercial use technically and economically feasible Of the antimony ores proper the major mineral is antimonite Sb2S3 which contains up to 714 percent Sb in rare cases antimony ores are represented by complex sulfides of antimony

Antimony is also used for pigments in plastics paints rubber and for a wide variety of minor uses including medicines fireworks and others Antimony oxide is a brilliant yellow color accounting for much of the pigment use A tiny amount of highly purified antimony metal is used in the computer industry to make semiconductors

Of the antimony ores proper the major mineral is antimonite Sb 2 S 3 which contains up to 714 percent Sb in rare cases antimony ores are represented by complex sulfides of antimony copper mercury lead and iron berthierite jamesonite tetrahedrite livingstonite as well as by oxides and oxychlorides senarmontite nadorite of antimony The content of Sb ranges from 1 to 10 percent in

Extraction of Antimony Antimony is extracted mainly from ores containing antimony trisulphide in the form of stibnite Rich ores are first subjected to liquation whereby the fusible sulphide is removed from the gangue and concentrated The reduction in pots is carried out in

Antimony III Sulfide The chief ore of antimony is stibnite Sb 2 S 3 antimony trisulfide which is produced in China and covers threefourths of the worlds mined antimony It is also found in isomorphous mixture with arsenic as allemonite The pure antimony is produced from the ore by roasting it to form the oxide then reducing

Antimony trioxide is tyically produced by roasting stibnite ores which are reported to contain 55 antimony The production of antimony trioxide ocurs as a vapourphase reaction at temperatures in excess of 1550°C The stoiehiometric addition of oxygen to the feed ore produces the desired product

Stibnite Sb2S3 is the predominant ore mineral of antimony The most important use of antimony metal is as a hardener in lead for storage batteries The metal also finds applications in solders and other alloys Antimony trioxide is the most important of the antimony compounds and is primarily used in flameretardant formulations
