Processing of Magnetite Iron Ores - Comparing Grinding ...

Pyrrhotite is the stable iron sulfide for oxygen fugacities fO 2 < FMQ (fayalite (FeSiO 4) ↔ magnetite + quartz), whereas paramagnetic pyrite (FeS 2) is dominant under the more oxidizing conditions in the Earth's crust (Lorand et al., 2005). Martian meteorites contain about as much pyrrhotite as magnetite.

Sep 01, 2013· The hydroxide layer formed is stable under diffused oxygen (Adam et al., 1984).Fe ions are present within the pyrrhotite and magnetite minerals. Cline et al. (1974) suggested that the refractory nature of pyrrhotite stems from an electrochemical reaction (oxidation) of pyrrhotite surfaces in the presence of magnetite. They tested mixtures of pyrrhotite–quartz and pyrrhotite–magnetite …

Pyrrhotite - an overview | ScienceDirect Topics

Formation of pyrrhotite at the expense of magnetite would thus lead a significant decrease in magnetic susceptibility of the sediments, which is not observed (Figure 2b). Thermochemical sulfate reduction occurs at high diagenetic temperatures (160–180°C) and over longer time intervals, from several tens of thousands to a few millions of ...

The Savage River Ore Formation Theories | SpringerLink

A symplectite of pyrite and magnetite in the massive sulphide ore of the Mashan mine, Anhui Province, is interpreted to have been formed by their replacing earlier pyrrhotite. The compositions of pyrrhotite, pyrite and magnetite related to this texture are given by electron microprobe analysis. Such a texture is likely to be formed when the ore-forming system reaches the three-phase point of ...

Accurate survey benefits mine expansion

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.
