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. Today, it is used as an ornamental stone, as well as a very popular stone for amateur collectors.

The Renaissance of Iron Pyrite Photovoltaics: Progress

Jun 27, 2014Since iron is in an oxidation state of 2+ in pyrite, this leaves six electrons remaining to fill up the three t 2g orbitals, making it a diamagnetic low-spin semiconductor. The splitting between these two orbital sets controls the band gap of the semiconductor and for pyrite it has been found that this gap is 0.95 eV.

pyrite

Nodules of pyrite have been found in prehistoric burial mounds, which suggests their use as a means of producing fire. Wheel-lock guns, in which a spring-driven serrated wheel rotated against a piece of pyrite, were used before development of the flintlock. Pure pyrite (FeS 2) contains 46.67 percent iron and 53.33 percent sulfur by weight.

If you have only a few pounds, it can be roasted by heat in the open air and then mixed with a flux like sodium borate and melted with a collector metal like copper. The melt can be poured into a mold and the gold will now be alloyed in the copper. An ounce of copper per pound of roasted pyrite will be plenty.
