  • OVERVIEW: Pyrite - Ask Jon Eakes

    The ferric iron attacks the Pyrite to create more ferrous iron, which just feeds the bacteria and the cycle continues until the water, the oxygen or the Pyrite is depleted. The problem with this for us is that all this activity causes the mass of Pyrite to swell.

    Natural gold tends to be anhedral (irregularly shaped), whereas pyrite comes as either cubes or multifaceted crystals. Pyrite can often be distinguished by the striations which, in many cases, can be seen on its surface. Chalcopyrite is brighter yellow with a greenish hue when wet and is softer (3.54 on Mohs39; scale).
