ʻO ka Iron Sulfide Pyrite: He alakaʻi piha ʻo Iron sulfide pyrite, i ʻike ʻia ʻo ke gula naʻaupō, he mineral maʻamau me ka mōʻaukala hoihoi a me nā noi like ʻole. Hoʻopili kēia alakaʻi i kāna mau waiwai, hoʻohana, a me ke koʻikoʻi o ke kaiapuni.

ʻO ka Iron Sulfide Pyrite: He alakaʻi piha

Iron sulfide pyrite (FeS₂), i kuhi pinepine ʻia ʻo ke gula ma muli o kona kala melemele keleawe, he mineral i loaʻa i nā wahi āpau i loaʻa i nā ʻano honua honua. Hāʻawi kēia alakaʻi i kahi ʻike piha o hao sulfide pyrite, e uhi ana i kona mau waiwai, hoʻokumu, hoʻohana, a me ka hopena o ke kaiapuni. ka hoomaopopo ana hao sulfide pyrite He mea koʻikoʻi ia ma nā ʻano he nui, mai ka mining a me ka metallurgy a hiki i ka hoʻoponopono ʻana i ke kaiapuni a me nā pōʻaiapili mōʻaukala.

ʻO ke kino a me ke kino o Pyrite

ʻO ka hiʻohiʻona a me ke ʻano Crystal

Pyrite hao sulfide ʻike pinepine ʻia e like me nā kristal keleawe-melemele me ka ʻulaʻula metala. ʻO kona ʻano aniani he cubic, hana pinepine i nā cubes ʻokoʻa a i ʻole pyritohedrons. Eia nō naʻe, hiki ke hana ʻia ma nā ʻano nui, granular, a hoʻolaha paha. Ka paakiki o hao sulfide pyrite ʻo 6-6.5 ma ka pālākiō Mohs, ʻano paʻakikī.

Hoʻohui Kimia a me nā hana

ʻO ke kumu kemika o Pyrite, FeS₂, hōʻike i kona haku: hao a me ka sulfur. Paʻa paʻa ia ma lalo o nā kūlana maʻamau, akā hiki ke oxidize i ka wā e ʻike ʻia ai i ka ea a me ka wai, e hana ana i ka sulfuric acid a me ka hao hydroxides. ʻO kēia kaʻina hana oxidation, i kapa ʻia ʻo acid mine drainage (AMD), he mau hopena koʻikoʻi koʻikoʻi, e kūkākūkā ʻia ma hope. He kumu nui kēia ʻano hana kemika i kāna mau noi ʻoihana a me nā hopohopo kaiapuni.

Ka hookumu ana a me ka loaa ana o Pyrite

Pyrite hao sulfide ʻano i loko o nā ʻano hoʻonohonoho honua, pili pinepine me nā pōhaku sedimentary, nā veins hydrothermal, a me nā pōhaku metamorphic. Hiki iā ia ke hana ma o nā kaʻina biogenic a me abiogenic. ʻO ka nui o ka hao a me ka sulfur i loko o ke kaiapuni he kuleana koʻikoʻi i kāna hoʻolaha ākea. Nui nā wahi waiwai i hao sulfide pyrite ʻO nā waihona hoʻi nā wahi o nā hana ʻoihana koʻikoʻi.

Na Hana Hana o Pyrite

Hana ʻia ka ʻakika Sulfuric

Ma ka mōʻaukala, hao sulfide pyrite he kumu nui o ka sulfur no ka hana ʻana i ka sulfuric acid. ʻOiai ʻoi aku ka nui o nā kumu ʻē aʻe, pili mau ka pyrite i kekahi mau wahi a me nā kaʻina hana. ʻO ke ahi o ka pyrite e hoʻopuka i ka sulfur dioxide (SO₂), a laila hoʻololi ʻia i ka waikawa sulfuric. ʻO kēia kaʻina hana, ʻoiai koʻikoʻi, kōkua pū kekahi i ka pollution ea inā ʻaʻole mālama pono ʻia.

Nā hoʻohana ʻē aʻe

Ma waho aʻe o ka hana sulfuric acid, hao sulfide pyrite loaʻa nā noi i ka hana ʻana i ka hao a me ke kila, ma ke ʻano he puaʻa i nā pena, a i ka hana ʻana i kekahi mau mea kemika. ʻO kāna mau waiwai kūʻokoʻa e lilo ia i kumu waiwai ma nā ʻano ʻenehana like ʻole.

Ka hopena o ka Pyrite

ʻO ka wai wai koʻu ʻakika (AMD)

Ka oxidation o hao sulfide pyrite ʻO ia ke kumu nui o ka waiʻawaʻawa mine drainage (AMD), kahi pilikia kaiapuni nui. Hoʻohaumia ʻo AMD i nā kumu wai me nā metala kaumaha a me ka waikawa sulfuric, e hōʻino ana i ke ola wai a me nā kaiaola. He mea koʻikoʻi nā hoʻolālā mitigation e hōʻemi i ka hopena o ke kaiapuni o ka pyrite oxidation. ʻO ka hoʻokele pono ʻana i nā huelo koʻu a me ka hoʻohana ʻana i nā ʻenehana hoʻoponopono he mau hana koʻikoʻi i ka hōʻemi ʻana i ka AMD.

Papa: Hoʻohālikelike i ka Pyrite me nā Sulfides hao ʻē aʻe
