Both pyrite and marcasite have very low solubility in HCl, and the only available method of removal in the oil industry is milling. The milling operation failed to solve the problem, therefore, the production was stopped until finding an alternative solution. An effective treatment strategy proposed to remove the scale efficiently; the technical proposal was designed taking into consideration

Marcasite (FeS 2) is an orthorhombic modification of the substance FeS 2 and is generally associated with sedimentary rocks in the form of spherical aggregates. Marcasite crystallizes at low temperatures from solutions containing ferrous sulfate, and is never found as a primary mineral in igneous rocks. Pyrrhotite (FeS) (Fig. ) is usually found in basic and ultrabasic igneous rocks in the

14/07/2020· Marcasite is a soft stone and is particularly susceptible to nicks and cracks. Store each piece in a separate, soft pouch to avoid damage from other stones. Do not use water or liquid jewellery cleaner to clean marcasite jewellery, as the glue securing the stone can dissolve with repeated exposure. Lightly buff each piece with a soft, dry cloth and do not use an ultrasonic jewellery cleaner

01/09/2016· The adsorption of cyanide ions (CN −) on pyrite, marcasite and pyrrhotite surfaces was studied using density functional depressing effects of CN − on these three minerals were then investigated by flotation tests. The calculated results show that the adsorption energy of CN − on the marcasite surface is the largest, − kJ/mol; followed by pyrrhotite, − kJ/mol
Marcasite is the lesser known companion of the famous mineral has the same chemical formula as Pyrite, but crystallizes in a different crystal system, thereby making it a scientifically distinct mineral species. Aggregates of iron sulfide (FeS 2) where the crystal structure cannot be determined without complex analysis may be wrongly eled by dealers and collectors.
