For example, pyrite and marcasite, both iron sulfides, have the formula FeS 2 ; however, the former is isometric while the latter is orthorhombic.

Difference Between Pyrite and Chalcopyrite

2016/3/29Pyrite is a sulfide mineral containing iron (Fe) and sulfur (S) as structural elements. Its chemical formula is FeS 2. It is also known as iron pyrite and "fool's gold" due to its pale-brass yellow color. In the ancient days, people misunderstood pyrite as gold since it Get price

How do pyrite and pyrrhotite damage building

Pyrite and pyrrhotite are minerals known as iron sulfides. When iron sulfides are exposed to water and oxygen, a series of chemical reactions breaks down the iron sulfides and forms new minerals called sulfates. These sulfates take up more space than the original iron sulfides. As they grow, the new sulfate minerals push against the surrounding rock, causing it to swell and crack. Get price

Pyrite – Witches Of The Craft

separation of pyrite and pyrrhotite from iron ore

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.
