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.

“Historically, pyrrhotite rejection has been successful by using appropriate reagents, pulp density, Eh control all play a role in improving selectivity of the economic mineral versus pyrrhotite. However, the factors listed above tend to be successful on the monoclinic variety and have less of an impact on the hexagonal polytype.

Cyanide Leaching and Decomposition of Pyrrhotite
Thus, pyrrhotite is not only a cyanicide but it also consumes oxygen in solution necessary for gold dissolution. Pyrrhotite, if kept dry, is stable but in the presence of water and air, it breaks down rapidly forming such compounds as sulphuric acid, ferrous sulphate, …
PYRRHOTITE (Iron Sulfide)
When pyrrhotite is low in sulfur and the formula is closer to true FeS, then the structure is hexagonal. But when it is high in sulfur, the structure is monoclinic. Clearly two different symmetries, two different formulae; therefore, two different minerals . . . except, that in natural pyrrhotite crystals both phases are present in the same ...
