Chemical Properties

Formula: FeS2

Class: sulfide

Characteristics:

(1) In oxidative environment, pyrite often decomposes into sulfate (such as jarosite) and hydrate (such as goethite), which form iron.

(2) After oxidation and hydrolysis, pyrite splits into vitiol and sulfate that make underground water acid.

(3) Slightly dissolvable in nitric acid.
