2 Antimony sulfide Ore Quality Standard oxide antimony ore can refer to the above specification and should be reduced the price by the Sb content Pricing regulation refer to Group’s price list Antimony Ore relevant Specification and Stipulation for Harmful Elements Our Group could deal with the

Antimony sulfide It’s at the heart of the first chemical equation and makes Hayley Birch think of quiche This week’s compound is antimony sulfide

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

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

Alternatively it can be sulfide ore the mineral is stibnite that has been upgraded by hand sorting to 3060 contained antimony Hand sot is typically a mixture of sulfide and oxide minerals from Mexico · “Sulfide concentrates ” are usually flotation concentrates produced in a mill that will range from 5068 contained antimony The mineral is usually stibnite and the theoretical maximum antimony content is

the element in any case he described the extraction of metallic antimony from its sulfide ore in his treatise “The Triumphal Chariot of Antimony” published sometime be tween AD1350 and 1600 Li 1953 Pliny the Elder named the metal stibium and the eighth century Arabian alchemist Geber Jabir referred to it as “antimonium”

The successful cyanidation of gold ores containing appreciable amounts of arsenic or antimony sulphide minerals such as orpiment realgar and stibnite is usually difficult or even impossible Extractions are low and the solutions soon become ‘foul’ The gold in such ores could be free and uncoated and no trouble in dissolving it in clean cyanide solutions would be expected

SULFIDE ORES The mineral dressing of sulfide ores is primarily accomplished by flotation although it can be accomplished by gravity and hand sort methods Recoveries of unoxidized sulfides can be in the mid 90 range with concentrate grades of 60 to 68 for stibnite ores

Antimony Ore The annual production of antimony in capitalist and developing countries was 40000–50000 tons in 1974 of which 90 percent came from monometallic ores onethird from blanket deposits twothirds from crossveins 6 percent from complex ores and 4

stibnite contains two and a half times more Sb than the mixedsulfide Ore 1 the amounts of Sb leached from both specimens are similar On the other hand although both Ore 1 and Ore 2 have the same initial Zn concentration the amount of Zn leached from Ore 2
