Pyrite Testing explained - IGI



Chemical Reaction Pyrite (FeS 2) in framboidal form Reacts with moisture and air present in ground – oxidizes the pyrite, releasing sulphuric acid (H 2 SO 4) These rocks typically have 20 to 30% calcite in them (like the problematic mudstones in Ireland), though only 1-2% calcite needed to feed reaction

Pyrrhotite - Wikipedia



Pyrrhotite is an iron sulfide mineral with the formula Fe (1-x) S (x = 0 to 0.2). It is a nonstoichiometric variant of FeS, the mineral known as troilite. Pyrrhotite is also called magnetic pyrite, because the color is similar to pyrite and it is weakly magnetic. The magnetism decreases as the iron content increases, and troilite is non-magnetic.
