Iron Pyrite (Iron 11 Sulfidi): A Comprehensive GuideIron pyrite, yomwe imadziwikanso kuti fool's gold, ndi mchere wopangidwa mwachilengedwe wopangidwa makamaka ndi chitsulo 11 sulfide (FeS?). Bukhuli limapereka chithunzithunzi chatsatanetsatane cha katundu wake, ntchito zake, ndi kufunika kwa chilengedwe.

Zakuthupi ndi Zamankhwala za Iron Pyrite

Iron 11 sulfide imadziwika ndi mtundu wake wosiyana wa brassy-yellow ndi zitsulo zonyezimira. Kulimba kwake ndi 6-6.5 pa sikelo ya Mohs, kutanthauza kuti ndi yolimba komanso yosagwira kukanda. Mwa mankhwala, ndi iron sulfide, yomwe imadziwika mosavuta kudzera mu mawonekedwe ake a cubic crystal. Imakhala yosagwira ntchito mumlengalenga wamba koma imatha kuchitapo kanthu ndi mpweya ndi madzi kupanga sulfuric acid, njira yotchedwa acid mine drainage, yomwe tidzakambirana pambuyo pake. Zomwe zimapangidwira zimatha kusiyana pang'ono kutengera malo ndi momwe zimakhalira. Zonyansa zina zingaphatikizepo arsenic, cobalt, kapena faifi tambala.

Kuzindikira Iron Pyrite

Kusiyanitsa chitsulo 11 sulfide kuchokera ku golidi weniweni kumafuna kuyang'anitsitsa mosamala. Ngakhale kuti mofanana ndi mtundu, pyrite nthawi zambiri imakhala yonyezimira ndipo imasiya mzere wakuda wobiriwira-wakuda pamene imatikita pamtunda wolimba, mosiyana ndi golide, yomwe imasiya golide. Kuyesa kosavuta kwa asidi kungatsimikizirenso kuti ndi ndani. Pyrite imachita ndi zidulo zamphamvu, kutulutsa mpweya wa hydrogen sulfide, womwe uli ndi fungo la dzira lovunda.

Kugwiritsa ntchito Iron Pyrite

Zakale, chitsulo 11 sulfide wakhala gwero lalikulu la chitsulo ndi sulfure. Ngakhale kugwiritsidwa ntchito kwake ngati gwero lachitsulo chachindunji kwatsika chifukwa cha kupezeka kwa ore apamwamba kwambiri, kumakhalabe kofunikira m'njira zingapo zamafakitale:

1. Sufuric Acid Kupanga

Kugwiritsa ntchito kwambiri kwa chitsulo 11 sulfide ndi kupanga sulfuric acid (H?SO?). Kupyolera mu njira yotchedwa kuwotcha, pyrite imatenthedwa pamaso pa mpweya, kutembenuza sulfure kukhala sulfure dioxide (SO?), yomwe pambuyo pake imagwiritsidwa ntchito kupanga sulfuric acid. Izi ndizofunikira kwambiri m'mafakitale ambiri, kuphatikiza feteleza, mankhwala, ndi zitsulo.

2. Ntchito Zina

Zochepa za chitsulo 11 sulfide amagwiritsidwa ntchito popanga ma pigment, monga gwero la sulfure pazinthu zina zazitsulo, komanso kupanga mitundu ina ya konkire.

Zolinga Zachilengedwe: Kutayira kwa Acid Mine

The oxidation wa chitsulo 11 sulfide, makamaka pankhani ya migodi, ikhoza kuyambitsa vuto lalikulu la chilengedwe: acid mine drainage (AMD). Ikalowa mumlengalenga ndi madzi, pyrite imachita kupanga sulfuric acid, yomwe imatha kutulutsa zitsulo zolemera m'miyala yozungulira ndikuyipitsa magwero amadzi. Kuthamanga kwa asidi kumeneku kumatha kukhala ndi zotsatira zowononga zachilengedwe zam'madzi ndikuyika chiwopsezo ku thanzi la anthu.

Njira Zochepetsera

Njira zingapo zimagwiritsidwa ntchito pochepetsa kuwononga chilengedwe kwa AMD, kuphatikiza: Njira zochizira: Izi zimagwiritsa ntchito njira zachilengedwe, monga madambo, kuti achepetse acidity ndikuchotsa zitsulo zolemera. Njira zochiritsira zomwe zimagwira ntchito: Izi zimagwiritsa ntchito njira zamankhwala kapena zachilengedwe kuti zisungunuke madzi amchere asanalowe m'chilengedwe. Kupewa kuwonetseredwa: Kuchepetsa kuwonekera kwa pyrite mumpweya ndi madzi mkati ndi pambuyo pa migodi.

Mapeto

Iron 11 sulfide, ngakhale kuti kaŵirikaŵiri imanyalanyazidwa, imagwira ntchito yofunika kwambiri m’mafakitale angapo ndipo imakhala ndi zotsatirapo zazikulu za chilengedwe. Kumvetsetsa momwe zinthu zilili komanso momwe zingakhudzire chilengedwe ndikofunikira kwambiri pakuwongolera bwino zinthu komanso kuteteza chilengedwe. Kufufuza kwina ndi kukonza njira zochepetsera za AMD ndizofunikira kuti muchepetse zovuta zachilengedwe zomwe zimakhudzana ndi mchere wofunikirawu.

Kuti mumve zambiri pazinthu zokhazikika za silicon ndi mayankho, lingalirani zowunikira ntchito zatsopano zomwe zikuchitika Malingaliro a kampani Inner Mongolia Xinxin Silicon Industry Co.,Ltd. Kudzipereka kwawo kumayendedwe osamalira zachilengedwe kumagwirizana bwino ndi kufunikira kwa mayankho okhazikika m'malo omwe akhudzidwa ndi kukumba ndi kukonza mchere.
