extraction of iron from pyrite. Pyrite Iron pyrite is unstable at Earth's surface: iron pyrite exposed to atmospheric oxygen and water decomposes into iron oxides and sulfate. This process is accelerated by the action of Acidithiobacillus bacteria which oxidize pyrite to produce ferrous iron, sulfate, and protons (H+ 2.12.1.1 Sulfide mineral 2 ...

Three dissolution techniques (buffered dithionite, cold 1 M HCl, boiling 12 M HCl) were examined for their capacity to extract iron from a variety of iron minerals, and iron-bearing sediments, as a function of different extraction times and different grain sizes. All the iron oxides studied are quantitatively extracted by dithionite and boiling HCl (but not by cold HCl).

Recycling of iron from red mud by magnetic
2014-7-20 A recycling process of iron from red mud by magnetic separation is proposed, in which iron oxide (Fe 2 O 3) in red mud transforms to magnetite (Fe 3 O 4) by anaerobic co-roasting with pyrite (FeS 2). TG-DTA and XRD results showed that hematite was reduced to magnetite by the thermo-decomposed compounds (iron monosulfide, pyrrhotite and element sulfur) of pyrite.
