ʻO Pyrite, ka mea i kapa ʻia ʻo ke gula naʻaupō, he mineral sulfide maʻamau i loaʻa i nā ʻano hoʻonohonoho honua. Loaʻa iā ia kahi kala keleawe-melemele ʻokoʻa a me ka ʻulaʻula metala, i alakaʻi ai i kona inoa kapakapa. ʻOiai ua like paha ia me ke gula i ka maka i hoʻomaʻamaʻa ʻole ʻia, ʻokoʻa maoli ka pyrite ma ke ʻano o kona ʻano kino a me ke kino.
ʻO ka Pyrite he ʻano aniani cubic, me kēlā me kēia mole i haku ʻia me ka hao a me nā ʻātoma sulfur i hoʻonohonoho ʻia ma kahi ʻano kikoʻī. Loaʻa ia ma ke ʻano o nā kristal liʻiliʻi i hana maikaʻi ʻia, ʻoiai hiki ke hana ʻia ma ke ʻano he nui, granular aggregates.
Loaʻa ka Pyrite i loko o nā kaiapuni honua like ʻole, e like me nā pōhaku sedimentary, nā pōhaku metamorphic, a me nā waihona hydrothermal. Hoʻohui pinepine ʻia me nā minerale ʻē aʻe e like me quartz, calcite, a me ka galena.
ʻO kekahi o nā hiʻohiʻona ʻokoʻa o ka pyrite ʻo kona paʻakikī. Ma ka pālākiō Mohs, i hoʻohana ʻia e ana i ka paʻakikī o nā minerala, hāʻule ka pyrite i kahi 6.5, ʻoi aku ka palupalu ma mua o ka quartz akā ʻoi aku ka paʻakikī ma mua o ka talc. He mea maʻalahi kēia e ʻohi me ka pahi or mea ʻoi ʻē aʻe, akā paʻakikī ke ʻoki ʻia a pulverize.
Ma ka ʻāina, hiki ke loaʻa ka pyrite ma ka honua holoʻokoʻa, ʻoiai ʻoi aku ka maʻamau i kekahi mau wahi. Loaʻa pinepine ia ma nā waihona nui ma nā wahi e like me ʻAmelika Hema, Sepania, a me Kina. I ka ʻAmelika Hui Pū ʻIa, loaʻa maʻamau ia ma nā mauna ʻo Appalachian a ma nā mokuʻāina komohana, ʻo ia hoʻi ma Nevada a Hawaii.
ʻO kekahi o ka hoʻohana nui ʻana o ka pyrite he ʻano hao. He mea nui ka hao i ka hana ʻana i ke kila, a he kumu nui ka pyrite o kēia metala. Ma waho aʻe o kona hoʻohana ʻana i ka ʻoihana kila, hoʻohana pū ʻia ka pyrite ma ke ʻano he kumu sulfur a ma ke ʻano he catalyst i ka ʻoihana kemika.
ʻO Pyrite kekahi mea pāʻani nui i ka aʻo ʻO ka waiʻawaʻawa mine drainage, ʻo ia ka mea e hopohopo nui ai i ke kaiapuni ma nā wahi he nui o ka honua. Ke ʻike ʻia ka pyrite i ka ea a me ka wai, hana ia e hana i ka sulfuric acid, hiki ke hoʻokuʻu i nā metala kaumaha a me nā mea make ʻē aʻe mai ka pōhaku a me ka lepo a puni. Hiki i kēia ke hoʻohaumia i nā lako wai a hoʻopilikia nui i ke kaiapuni.
ʻOiai ka hopena maikaʻi ʻole o ke kaiapuni, noho mau ʻo pyrite i mineral koʻikoʻi i ka geology a me nā ʻoihana mining. ʻO kāna mau waiwai kūʻokoʻa a me ka laha ʻana e lilo ia i kumu waiwai nui e hoʻomau ʻia e hoʻohana ʻia no nā makahiki he nui e hiki mai ana.
