Acid sulfate soils explained | Environment, land and water ,
Iron Iron, in its reduced form (Fe 2+), reacts with the hydrogen sulfide (H 2 S) produced by the sulfate-reducing bacteria, to form pyrite (FeS 2) Iron is a very common mineral, so there is rarely a shortage in the environment Water movement As pyrite forms, bicarbonate also forms from the same reaction If it is not removed from the .
Pyrite, an iron sulfide, and hauerite, a manganese sulfide, seem tame in comparison to the rest of this Group If you have been to Graves Mountain and the Little Bob Mine in Georgia, then you know about the problems associated with pyrite When this combination of iron and sulfur (FeS2) weathers, the iron oxidizes (rusts away) and the sulfur .

IRON SULFIDE OXIDATION AND THE CHEMISTRY OF ACID ,
evaluate iron sulfide oxidation and the reactions of A13+, FeS+, Fe2+, and SO,*- under conditions of high leaching, (2) determine the composition of acid mine drainage under such conditions, and (3) utilize chem- ical equations to understand the management of geo- logic materials containing iron sulfid
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 ac Thermal decomposition of pyrite into FeS (iron sulfide) and elemental sulfur starts at 550 øC; at around 700 øC pS2 is about 1 atm
A group of compounds containing iron in +2 (ferrous) and +3 (ferric) valence states and sulfur in -2 (sulfide) valence stat Examples are ferric sulfide [Fe 2 S 3], ferrous sulfide [FeS] and iron disulfide (FeS 2, which is found in the minerals marcasite and pyrite)Fe 2 S 3 and FeS 2 are insoluble, but FeS dissolves in alkaline muds to form a gelatinous solid, Fe(OH) 2, and soluble S-2 ions
