17/12/2019A piece of pyrite has a passivated surface in its natural state i.e. it is shielded by the adsorption of oxygen, hydroxyls and the like held on its surface by van der Waal's forces and dangling bonds on the ridges of its micro-rugosity. This results in layers, a few molecules deep, which impede or prevent pyrite oxidising. Pyrite is brittle (

Pyrite: The mineral pyrite information and pictures

Pyrite was once used as a source of sulfur, but is now only a minor ore for both sulfur and iron. Pyrite from some localities is auriferous, and therefore is used as an ore of gold in gold-bearing localities. Pyrite was polished by the Native Americans in the early times and used as mirrors.
