Iron Pyrite: He Luʻu hohonu i loko o ka hao(II) SulphideIron(II) sulphide, i ʻike nui ʻia pyrite hao, he mineral hoʻohiwahiwa me ka nui o nā noi a me nā waiwai hoihoi. ʻIke ʻia kēia alakaʻi piha i ka haku mele ʻana, nā ʻano kino, ka hoʻokumu ʻana, ka hoʻohana ʻana, a me ka hopena o ke kaiapuni o pyrite hao. E noʻonoʻo mākou i kona koʻikoʻi ma nā ʻoihana like ʻole a kūkākūkā i kāna kuleana ma nā kaʻina hana honua.

Hoʻohui Kimia a me nā waiwai

Pirite hao (FeS?) he minela hao sulfide me kahi hoʻoheheʻe aniani kūbiko kūʻokoʻa. Hōʻike kona ʻano kemika i ka ratio 1:2 o ka hao(II) i ka sulfur. ʻO kēia haku mele ka hopena i kekahi mau hiʻohiʻona nui:

Na Waiwai Kino

Ka waihoʻoluʻu: He melemele maʻamau, me nā waihoʻoluʻu iridescent. Paʻakiki: Paʻakikī paʻakikī (6-6.5 ma ka pālākiō paʻakikī Mohs). Kaumaha kikoʻī: Ma kahi o 5.0 g/cm3. Kaha: ʻōmaʻomaʻo-ʻeleʻele a ʻeleʻele-ʻeleʻele paha. Māhele: Cubic, akā pinepine ʻole. Haʻihaʻi: Conchoidal.

Na Waiwai Kemika

Pirite hao ʻano paʻa ma lalo o nā kūlana maʻamau, akā hiki iā ia ke hana me ka oxygen a me ka wai e hana i ka sulfuric acid, kahi hana i kapa ʻia ʻo acid mine drainage. He mea koʻikoʻi kēia kaʻina hana i nā pōʻaiapuni a me nā hana eli. He exothermic loa ka hopena a hiki ke hoʻoulu i ka wela nui.

Hoʻokumu a me ka hanana

Pirite hao nā ʻano i loko o nā ʻano ʻāina like ʻole, ma o nā kaʻina hydrothermal, sedimentary deposition, a me ka hoʻololi metamorphic. He mineral maʻamau i loaʻa i loko o nā pōhaku sedimentary, nā pōhaku igneous, a me nā pōhaku metamorphic a puni ka honua. Hoʻopili pinepine ʻia nā waihona koʻikoʻi me nā hili lanahu, a loaʻa pinepine ʻia i nā veins hydrothermal.

Hoʻohana i ka Iron Pyrite

Ma ka mōʻaukala, pyrite hao Ua kuhi ʻia ʻo ia no ke gula (ʻo ke gula naʻaupō), akā he nui nā mea waiwai:

Noi Hana Hana

ʻOihana Sulfur: Pirite hao he kumu nui ia o ka sulfur no ka ʻoihana kemika, i hoʻohana ʻia i ka hana ʻana i ka sulfuric acid, nona nā noi ākea. ʻO ka hana ʻana o pyrite hao no ka hoʻohua ʻana i ka sulfur, ʻo ia hoʻi ke kālua ʻana (hoʻomaʻamaʻa ʻana i mua o ka ea). Mea Hana Hao: ʻOiai ʻaʻole maʻamau, pyrite hao hiki ke hoʻohana ʻia ma ke ʻano he puna hao, ʻoiai ʻoi aku ka maikaʻi o nā mea hao ʻē aʻe.

Nā hoʻohana ʻē aʻe

Pigments: Hoʻopili maikaʻi ʻia pyrite hao ua hoʻohana ʻia ma ke ʻano he puaʻa. ʻO nā kumu hoʻonani: ʻO kona hiʻohiʻona maikaʻi e kūpono ia no ka hoʻohana ʻana i nā mea nani, ʻoiai ʻo kona ʻano paʻakikī haʻahaʻa ʻoi aku ka maikaʻi no nā mea ʻaʻahu liʻiliʻi.

Ka hopena o ke kaiapuni

Ka oxidation o pyrite hao, ʻoi aku ka nui o nā hana eli, hiki ke alakaʻi i nā pilikia kaiapuni nui. Acid mine drainage (AMD) ma muli o kēia oxidation e hoʻohaumia i nā ala wai, e hoʻopōʻino i ke ola wai a me nā kaiaola. He mea koʻikoʻi nā hoʻolālā hoʻokele waiwai hoʻokele waiwai e hoʻēmi i ka hopena kaiapuni o pyrite hao oxidation.

Huli Huli Hou

E aʻo hou e pili ana i ka ʻeli ʻana a me ka hana ʻana i nā minerale like pyrite hao, e ʻimi i nā kumuwaiwai mai nā hui i hoʻolaʻa ʻia i ke kuleana kaiapuni ma ka ʻoihana mining. No ka ʻike e pili ana i nā noi kikoʻī a i ʻole nā waiwai kemika, e ʻimi i nā ʻikepili ʻepekema a me nā puke.
