Chemistry Stack Exchange is a question and answer site for scientists academics The reaction of iron with sulfur to produce Iron(II) sulfide is inconvenient (for me) Ask Question Asked 1 year stated that Fe2S3 disproportionated to mixtures of pyrite (FeS2) pyrrhotite and elemental S above temperatures of 10C

Oxidation of pyrite (FeS2) under anaerobic conditions in marine sediments is experimentally shown for the first time In slurry experiments with 55FeS2 and a MnO2 rich marine sediment an oxidation of 55FeS2 was detected which decreased with depth and decreasing concentration of MnO2 in the sediment FeS2 and iron sulfide (FeS) were oxidized chemically at pH 8 by MnO2 but not by nitrate

Pyrite is an iron sulfide which is found in abundance on the Earth It boasts of being the most common sulfide mineral found on the planet Owing to its brass-yellow metallic luster it resembles gold to a certain extent which has earned it the nickname 'fool's gold' in areas where it is quite popular As far as its uses are concerned there are quite a few to list but before we move

The presence of Mn suppresses the formation of iron sulfide (FeS) which has a lower melting point than MnS [2180F (1193C) for FeS vs Stabilizing Pearlite In Gray Cast Iron The deficits of copper iron and hydrogen sulfide in the cooler white smoker fluid could best be explained by the precipitation of copper- iron sulfide and iron sulfide (that is chalcopyrite and pyrite) within the mound

Oxidation of pyrite (FeS 2) under anaerobic conditions in marine sediments is experimentally shown for the first time In slurry experiments with 55 FeS 2 and a MnO 2 rich marine sediment an oxidation of 55 FeS 2 was detected which decreased with depth and decreasing concentration of MnO 2 in the sediment FeS 2 and iron sulfide (FeS) were oxidized chemically at pH 8 by MnO 2 but not by

The mineral marcasite sometimes called white iron pyrite is iron sulfide (FeS 2) with orthorhombic crystal structure It is physically and crystallographically distinct from pyrite which is iron sulfide with cubic crystal structure Both structures do have in common that they contain the disulfide S 2 2- ion having a short bonding distance between the sulfur atoms

The mineral pyrite or iron pyrite is iron sulfide FeS 2 It has isometric crystals that usually appear as cubes The cube faces may be striated (parallel lines on crystal surface or cleavage face) as a result of alternation of the cube and pyritohedron faces Pyrite also frequently occurs as octahedral crystals and as pyritohedra (a dodecahedron with pentagonal faces)

Iron Sulfide Iron Pyrite processing into its constituents

Pyrite (FeS2) is a very common mineral that can be found in virtually all geological environments Pyrite mineral form of FeS2 is largely Ferrous Sulphide or Iron Sulfide Ferrous Sulphide or Iron Sulfide is in the form Sticks Lumps and Powder

Iron as Fe 70-73% Sulphur as S 28-32% Iron (II) sulfide is a chemical compound with the formula FeS In practice iron sulfides are often non-stoichiometric Powdered iron sulfide is pyrophoric FeS Ferrous Sulfide or Iron Sulphide can be obtained by reacting iron and sulfur We can offer Ferrous Sulfide or Iron Sulphide in the form Sticks

PYRITE (Iron Sulfide) Bravoite is the name given to a nickel-rich iron sulfide It is closely related to pyrite but contains up to 20% nickel Some mineral books treat it as a variety of pyrite Pyrite is a polymorph of marcasite which means that it has the same chemistry FeS2 as marcasite but a different structure and therefore different

The iron sulfide mineral pyrite has been called fool's gold because of its pale brass yellow color and glistening metallic luster It is the most widespread and abundant sulfide mineral in rocks of all ages The cubic dodecahedral and octahedral crystals and the fine grain masses may be distinguished from gold by their higher Mohs hardness of 6 to 6 5 and their lower specific gravity of 4 9

Iron-monosulfide formation and oxidation in acid-sulfate soils Funding in addition to iron-disulfides (such as pyrite) ASS landscapes often contain large amounts of iron-monosulfide minerals The formation and oxidation of iron-monosulfides has a fundamental role in regulating water quality through effects on acidity dynamics and the mobility of iron sulfur and trace metals (Burton et

The mineral pyrite or iron pyrite is an iron sulfide with the formula Fe S 2 This mineral's metallic lustre and pale-to-normal brass-yellow colour have earned it the nickname fool's gold because of its resemblance to gold The term pyrite may also be used for some other sulphides such as

Anomalous enrichments of iron monosulfide in euxinic

It is well documented that sedimentary pyrite formation proceeds through an iron monosulfide (FeS) precursor Laboratory studies have traditionally indicated that intermediate S species such as elemental sulfur (S 0) or polysulfides (S x 2-) are responsible for the transformation of FeS to pyrite (FeS 2) Recent experimental work however has suggested that H 2 S may also be responsible for

The iron isotope signature of sedimentary pyrite is widely used to trace the microbial and redox states of the ocean yet the iron isotope fractionation accompanying pyrite formation in nature is difficult to constrain due to the complexity of the pyrite formation process difficulties in translating the iron isotope systematics of experimental studies to natural settings and insufficient

Pyrite remains in commercial use for the production of sulfur dioxide for use in such applications as the paper industry and in the manufacture of sulfuric acid Thermal decomposition of pyrite into FeS (iron sulfide) and elemental sulfur starts at 550 C at around 700 C pS2 is about 1 atm

Product Description Fools Gold - Iron Pyrite (Iron Sulfide) Peruvian Pictures are examples only Select from 6 different sizes 1/2 / 3/4 / 1 / 2 / 3 / 3-5 ( this is 1LB LOT - not 1 piece ) Iron Pyrite Aggregate is the classic Fool''s Gold Iron Pyrite is by far the most often mineral mistaken for real gold

Iron pyrite (FeS2 Fool's Gold) is a non-toxic earth abundant semiconductor that exhibits promise for use in energy conversion and storage devices such as the cathode material for batteries thermoelectrics and optoelectronics However pyrite's potential as an energy-critical material is being curbed due to problems with controlling composition stoichiometry and bulk and surface defects

FeS2 and iron sulfide (FeS) were oxidized chemically at pH 8 by MnO2 but not by nitrate or amorphic Fe(III) oxide Elemental sulfur and sulfate were the only products of FeS oxidation whereas FeS2 was oxidized to a variety of sulfur compounds mainly sulfate plus intermediates such as thiosulfate trithionate tetrathionate and pentathionate
