Jul 17 2012nbsp018332Iron precipitation Rich sulfide ore or liquated antimony sulfide crude antimony is reduced to metal by iron precipitation This is illustrated in Eq 6 This process consisting of heating molten antimony sulfide in crucibles with slightly more than the 6 Sb 2 S 3 3Fe 2Sb 3FeS theoretical amount of fine iron scrap depends on the
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 However there are companies in the United States that produce antimony
If antimony ore contains more than 90 stibnite it can be sold directly for producing antimony compounds or conversion to antimony metal Herbst et al 1985 Crude materials marketed for the manufacturing of pure antimony products mostly oxide consist of antimony sulfide concentrate and lump antimony sulfide ore USGS 2001 4
Antimony Ore Roasting Plant Oman Clean TeQ Water were engaged to provide the engineering procurement and construction of a 05MLd plant in Oman The plant uses a precipitation stage to remove antimony and arsenic followed by Clean TeQ Waters DESALX 174 technology to remove hardness and sulfates before continuing to reverse osmosis RO

Selective dissolution of stibnite from a complex sulfidic antimony ore containing pyrite by ozonation leaching in hydrochloric acid solution has been studied in the paper the precipitation
The concentrated solution containing dissolved silver is now above the ore and being diluted with water from d lets the chloride of silver fall as a precipitate on and throughout the ore The other plan is the precipitation of the silver together with the chlorides of lead and antimony outside of the leaching box
Antimony Smelting Mineral Processing Metallurgy The history of the antimony industry of China dates back to 1897 when the Tai Shing Co was formed under contract with the Hunan Bureau of Mines for the smelting of the ore to crude and in 1908 the Wah Chang Mining Smelting Co was formed for the smelting and refining of the ore and crude to regulus
antimony was added during the casting process Precipitates of antimony have a globular shape and are located between the grains of aluminium and eutectic Figs 1 and 2 For samples marked as 3 and 4 in which the Mn content was zero the precipitates of antimony have changed their morphology from the globular to irregular There
Aluminum hydroxide is not effective in removing antimony Precipitation with lime requires quite large quantities of lime in order to reduce residual Sb levels to desired levels Precipitation of the sulfide in the presence of FeII or FeIII may produce low residual concentrations but runs the risk of exposure to highly toxic hydrogen sulfide
The iron precipitation method is used to produce antimony metal from concen trated antimony ores or from the crude antimony issued from the liquation process In this process scrap iron is added to molten Sb 2S 3 to displace the antimony in order to form antimony metal and a
Antimony is dissolved in hot concentrated sulphuric acid H 2 SO 4 or nitric acid HNO 3 forming SbIII solutionsThe sulphuric acid reaction produces SO 2Antimony does not react with hydrochloric acid in the absence of oxygen

China now leads the world in antimony production having contributed during recent years something over 60 per cent of the worlds production The history of the antimony industry of China dates back to 1897 when the Tai Shing Co was formed under contract with the Hunan Bureau of Mines for the smelting of the ore to crude and in 1908 the Wah Chang Mining amp Smelting Co was formed for
Antimony is chalcophile occurring with sulfur and the heavy metals lead copper and silver Over a hundred minerals of antimony are found in nature Stibnite Sb 2 S 3 is the predominant ore mineral of antimony The most important use of antimony metal is as a hardener in lead for storage batteries
precipitation smelting of antimony ore is based on the great affinity of sulfur and oxygen to iron rather than to antimony The main purpose of meltings the antimony raw materials is the transfer of the main substance of ore antimony in a less contaminated by iron

We aimed to study the characteristics and the mechanism of the cumulative release of antimony at an antimony smelting slag stacking area in southern China A series of dynamic and static leaching experiments to simulate the effects of rainfall were carried out The results showed that the release of antimony from smelting slag increased with a decrease in the solidliquid ratio and the
