Pirita

Pirita
La pirita es un mineral conocido desde la antiguedad. Los griegos denominaban como pirita a algunos minerales que al ser golpeados o frotados desprendían chispas . En el siglo XVI se restringió a los sulfuros metálicos y en el siglos XVIII se acordó que las piritas eran tres: arsenopirita, calcopirita y pirita propiamente dicha. Hasta el siglo XIX el término no adquirió su significado actual. La pirita ha engañado a más de un buscador inexperto de oro por su semejanza con el metal precioso (por eso se la denominó oro de los locos); las inclusiones doradas que aparecen en el lapisázula, por ejemplo, son de pirita.

Polimorfos

Formación y ambiente

La pirita aparece en grandes concentraciones de distinto origen. Así es un mineral muy común en todos los yacimientos de sulfuros metálicos y en casi todas las rocas plutónicas, volcánicas, sedimentarias,y metamórficas.

Accesorio, hidrotermal, infiltración, magmático, metamórfico, postmagmático, postvolcánico, sedimentario.

Propiedades fisicas

Hábito: Forma los típicos cubos dorados o dodecaedros o maclas de penetración. Mas raras, pero tambien puede aparecer de cualquier otra forma, como la octaedricas o algunas muy curiosas como la diquisdodecaedrica o diploedrica con formas extrañas de 24 caras o incluso la botroidal (como frambuesas), estalactítico, esferoidal, radiado, o en formas macladas, las mas buscadas las Cruces de hierro, formados por dos cristales pentagonododecaedricos girados 90 grados en luno respecto al otro recordando a un motivo heraldico. Tambien puede aparecer sustityendo por ejemplo a un fosil, como un ammonites (te encuentras el caracol dorado) conocidos como Ammonites piritosos y los Trilobites piritizados

Yacimientos y localidades de interés

El yacimiento más importante del mundo, explotado desde hace 30 siglos, esta en Riotinto, Huelva. Hay también yacimienetos en Cartagena, Murcia, Santander y La Rioja (Ambas Aguas y Navajún). En 1985 se encontró en esta región un extraordinario ejemplar que alcanzaba los 35 kilos y presentaba múltiples cristales cúbicos.

Magníficos dodecaedros han sido encontrados en Muros y Castropol (Asturias) en algunos casos icosaedros y cubos asociados a oro y cobre. En Reocín (Cantabria) están asociados bellos ejemplares a la dolomita.

Usos y apliaciones

Fue empleada de antiguo en los eslabones de las armas de fuego como piedra foguera, pero por su poca dureza fue sustituida pronto. Hoy día su principal aplicación está en la extracción de ácido sulfúrico. A veces es posible extraer de ella cantidades de cobre y oro, con los que a menudo aparece asociada. La obtención del ácido se produce mediante el «tueste» del mineral, es decir, se calienta hasta altas temperaturas en presencia de oxígeno, ya que así emana dióxido de azufre (SO2) y posteriormente este se transforma artificialmente a trióxido de azufre (SO3) al que se añade agua para transformarlo en ácido.

Como piedra ornamental, de interés científico y coleccionista.
