pyrite minérale

Pyrite - the fools gold. Pyrite is much more commonly known in laymans terms as fools gold. This is because, when gold mining was popular, pyrite could often be mistaken for gold due to its shining gold exterior. Of course, they are actually quite different minerals, but to the untrained eye, the mistake could be an easy one to make.

Falling between 6 and 6.5 on the Mohs scale of hardness, it is a pretty hard mineral. It has a cubic (isometric) crystal system, meaning that it has three equal axes that fall at 90 degrees from each other. …
Pyrite-pyrrhotite ratios change during metamorphism as prograde heating results in sulphur release from pyrite to form pyrrhotite and as retrograde cooling permits re-growth of pyrite as the pyrrhotite releases sulphur. Retrograde growth of pyrite may encapsulate textures developed during earlier stages as well as preserve evidence of ...

The study of nanominerals in roasted pyrite ash from coal rejects is important to develop an understanding on the nature of this by-product, and to assess the interaction between emitted nanominerals, ultra-fine particles, and atmospheric gases, rain or body fluids, and thus to evaluate the environmental and health impacts of pyrite ash materials.
