Antimony is not an abundant element but is found in small quantities in over 100 mineral species It is most often found as antimony III sulfide It is extracted by roasting the antimony III sulfide to the oxide and then reducing with carbon Antimony can also be found as the native metal China produces 88% of the world s antimony Other producers are Bolivia Russia and Tajikistan Help
Antimony is transported in the blood its distribution varying among species and dependent on its valence state Felicetti et al 1974b Antimony is not metabolized but may bind to macromolecules and react covalently with sulfhydryl and phosphate groups ATSDR 1990
Antimony is a minor ore of the element antimony although most antimony comes from antimony compounds namely Stibnite which are much greater in abundance Antimony has a very interesting property It is similar to water in that instead of contracting when it solidifies like all other matter it expands
Valid Species Pre IMA 1832 Locality Ichinokawa Shikoku Japan Link to Location Data Name Origin From the Greek stimmi or stibi antimony thence to the Latin stibium Also from the Greek anthemon flower in allusion to the form of crystal druses Name Pronunciation Stibnite Synonym Antimonite Antimony Glance
This table compares the known valid mineral species listed listed with Antimony and the other elements listed based on the official IMA formula Note that unlike other sections on this page this includes non essential elements The first data column contains the total number of minerals listed with Antimony and the element listed for that row
The proposed methods are also applicable to high purity copper metal and copper and lead base alloys In the spectrophotometric iodide method the importance of the preliminary oxidation of all of the antimony to antimony V to avoid the formation of an unreactive species is shown
antimony is one of a few elements that expand as they freeze Antimony is a poor conductor of electricity and heat and can be toxic in some cases but less so in solid form More than 100 mineral species of antimony are known; however it most commonly combines with sulfur to form antimony sulfide or stibnite Sb 2S 3 It also combines with lead and sulfur to form the mineral
Mine workers are often exposed directly to stibnite ore antimony sulfide and to airborne antimony via inhalation and skin exposure As part of their Environmental Geochemistry and Health study Zhu and scientists from the Chinese Academy of Sciences conducted field work at Xikuangshan in 2021 drawing multiple water samples from 18 different sample sites Samples were shipped back to
The mineral species cobaltite CoAsS is a sulfosalt and calaverite AuTe 2 is a telluride of the AX 2 type Species of the A 2 X 3 type include the semimetal sulfides orpiment As 2 S 3 and bismuthinite Bi 2 S 3 while the sulfosalts pyrargyrite Ag 3 SbS 3 and proustite Ag 3 AsS 3 are of the form A 4 X 3
The extraction of Antimony from its ore The following photographic documentation of the process of extracting antimony from its ore made by one of my French correspondents and one of his colleagues He says These pictures describe an experiment undertaken a few years ago related to the Dry path of antimony or Stibnite Path as followed by E Canseliet and I guess but opinions could differ

Antimony is a member of group 15 of the periodic table one of the elements called pnictogens and has an electronegativity of In accordance with periodic trends it is more electronegative than tin or bismuth and less electronegative than tellurium or is stable in air at room temperature but reacts with oxygen if heated to produce antimony trioxide Sb 2 O 3
This ore was known as Faczebajer weißes blättriges Golderz white leafy gold ore from Faczebaja German name of Facebánya now Fața Băii in Alba County or antimonalischer Goldkies antimonic gold pyrite and according to Anton von Rupprecht was Spießglaskönig argent molybdique containing native antimony
Carcinogenic effects of antimony trioxide and antimony ore concentrate in rats Groth DH Stettler LE Burg JR Busey WM Grant GC Wong L This study was initiated because of a suspected increase in incidence of lung cancer in antimony smelter workers in England Three groups of 8 mo old Wistar derived rats 90 males and 90 females per group were exposed by inhalation to either Sb2O3 [time
Antimony and its compounds were known to the ancients and there is a 5 000 year old antimony vase in the Louvre in Paris Antimony sulfide Sb 2 S 3 is mentioned in an Egyptian papyrus of the 16 th century BC The black form of this pigment which occurs naturally as the mineral stibnite was used as mascara and known as most famous user was the temptress Jezebel whose exploits are
The combined Au Sb flotation concentrate is produced from the high antimony ore at Mill 1 via gravitation/flotation then filtration and at a later date metal production The key is that Polyus can get a premium for the antimony ore or concentrate but the project doesnt require much in the way of capital or operational expenses
The extraction of antimony from ores depends on the quality of the ore and composition of the ore Most antimony is mined as the sulfide; lower grade ores are concentrated by froth flotation while higher grade ores are heated to 500 600°C the temperature at which stibnite melts and is separated from the gangue minerals Antimony can be isolated from the crude antimony …

Approximately 20 000 metric tons of antimony trioxide [1309 64 4] commonly referred to as antimony oxide Sb 2 O 3 was used in the United States in 1990 to impart flame retardancy to plastics Although antimony trioxide is found in nature it is too impure to be used Flame retardant grades of antimony oxides are manufactured from either antimony metal or the sulfide ore by oxidation in air
