2 Pyrite oxidation has been studied extensively in the past because of its importance in sulfide mineral separations by flotation in the generation of acid in mine waters and in leaching of pyrite. The oxidation of pyrite also plays key role in supergene alteration of ore deposits the formation of acid sulfate soils etc. Pyrite oxidation is generally recognied as a complicated process

    Pyrite is an iron sulfide. Sulfur managed to combine with iron because its strongest competitor oxygen was nowhere to be found. Oxygen was consumed by decomposing organic matter or maybe we should say it the other way around oxygen was busy destroying the organic stuff and lost its freedom in the process. This is why we often find it in coal

    Degeneration of shale caused by oxygen in aqueous drilling fracturing and completion fluids is minimied by introducing imidaolines modified so that they will be attracted efficiently to pyrites in the shale thereby forming a protective coating on the pyrites. Inhibiting oxidation of the pyrites sharply reduces physical degradation of the shale and the generation of undesirable oxides in
