Removal of Pyrite and Different Types of Iron Sulfide ...

Pyrite, which has good thermal stability, tends to deposit at shallower places downhole and is inert to acid. Other iron sulfides react with acids. Thermal stable species are much harder to be removed by acids. Thus the iron sulfide downhole are mainly pyrrhotite, pyrite, marcasite and mackinawite, in which pyrite cannot be removed by acid treatment.

Thus the iron sulfide downhole are mainly pyrrhotite, pyrite, marcasite and mackinawite, in which pyrite cannot be removed by acid treatment. Both pyrite and marcasite have very low solubility in HCl, and the only available method of removal in the oil industry is to mill these types of scale.

Banded iron formations which usually contain iron as oxides (magnetite, hematite) are much better ores of iron. Sulfur extracted from pyrite is mostly used to make sulfuric acid which has many industrial applications. Because of that it is said that the amount of sulfuric acid produced is a good indicator of country’s industrial strength.

In part because of the abundance of pyrite in the shale, the described decomposition of the iron pyrite contributes significantly to the undesirable structural disintegration of the shale which plagues hydrocarbon recovery operations throughout the industry. Oxygen reacts both with iron and sulfur, causing rapid disintegration of the pyrite.

Pyrite - Wikipedia

Iron pyrite is unstable at Earths surface: iron pyrite exposed to air and water decomposes into iron oxides and sulfate. This process is hastened by the action of Acidithiobacillus bacteria which oxidize the pyrite to produce ferrous iron and sulfate. These reactions occur more rapidly when the pyrite is in fine crystals and dust, which is the form it takes in most mining operations.
