I-FeSi75-A

I-Iron Pyrite (I-Iron 11 Sulfidi): I-Comprehensive GuideIron pyrite, eyaziwa nangokuthi igolide lesiwula, iyimineral eyenzeka ngokwemvelo ehlanganiswe ngokuyinhloko insimbi 11 sulfide (FeS?). Lo mhlahlandlela unikeza ukubuka kabanzi kwezakhiwo zawo, izinhlelo zokusebenza, nokubaluleka kwendawo ezungezile.

Izakhiwo zomzimba nezekhemikhali ze-Iron Pyrite

I-Iron 11 sulfide ibonakala ngombala wayo ohlukile wethusi-ophuzi kanye nokucwebezela kwensimbi. Ubulukhuni bayo bungu-6-6.5 esikalini se-Mohs, okusho ukuthi ilukhuni futhi ayivumi ukunwaya. Ngokwekhemikhali, iyi-iron sulfide, ebonakala kalula ngesakhiwo sayo sekristalu eyi-cubic. Ayisebenzi uma iqhathaniswa nezimo ezivamile zomkhathi kodwa ingasabela ngomoya-mpilo namanzi ukuze yakhe i-sulfuric acid, inqubo eyaziwa ngokuthi i-acid mine drainage, esizoxoxa ngayo kamuva. Ukwakheka kwamakhemikhali okuqondile kungahluka kancane kuye ngendawo nezimo zejoloji elakheke ngaphansi kwazo. Okunye ukungcola kungase kuhlanganise i-arsenic, i-cobalt, noma i-nickel.

Ukuhlonza Iron Pyrite

Ukwehlukanisa insimbi 11 sulfide kusuka egolideni langempela kudinga ukubhekwa ngokucophelela. Nakuba ifana ngombala, i-pyrite ivamise ukuba brittle futhi izoshiya i-streak emnyama ngokuluhlaza okotshani lapho ihlikihlwa endaweni eqinile, ngokungafani negolide, eshiya umugqa osagolide. Ukuhlolwa okulula kwe-asidi nakho kungaqinisekisa ubunikazi bayo. I-pyrite izosabela ngama-asidi aqinile, ikhiqize igesi ye-hydrogen sulfide, enephunga leqanda elibolile.

Izicelo ze-Iron Pyrite

Ngokomlando, insimbi 11 sulfide kube umthombo obalulekile wensimbi nesibabule. Nakuba ukusetshenziswa kwayo njengomthombo wensimbi oqondile kwehlile ngenxa yokutholakala kwezinsimbi ezisezingeni eliphezulu, kusabalulekile ezinqubweni eziningana zezimboni:

1. Ukukhiqizwa kwe-Sulfur Acid

Uhlelo lokusebenza olubaluleke kakhulu lwe insimbi 11 sulfide is in the production of sulfuric acid (H?SO?). Ngenqubo ebizwa ngokuthi ukugazinga, i-pyrite iyashiswa lapho kukhona umoya, iguqule isibabule sibe yi-sulfur dioxide (SO?), kamuva esetshenziselwe ukukhiqiza i-sulfuric acid. Le nqubo ibalulekile ezimbonini eziningi, okuhlanganisa umanyolo, amakhemikhali, nokukhiqizwa kwensimbi.

2. Ezinye izinhlelo zokusebenza

Amanani amancane we insimbi 11 sulfide asetshenziswa ekukhiqizeni ama-pigments, njengomthombo wesibabule kwezinye izinqubo ze-metallurgical, nasekukhiqizeni izinhlobo ezithile zikakhonkolo.

Ukucatshangelwa kwezemvelo: I-Acid Mine Drainage

I-oxidation ye insimbi 11 sulfide, ikakhulukazi kumongo wezimayini, kungaholela enkingeni ebalulekile yemvelo: i-acid mine drainage (AMD). Lapho ivezwe emoyeni nasemanzini, i-pyrite isabela yenze i-sulfuric acid, engakhipha izinsimbi ezisindayo emadwaleni azungezile futhi ingcolise imithombo yamanzi. Lokhu kugeleza okune-asidi kungaba nemiphumela elimazayo kuzinto eziphilayo zasemanzini futhi kudale izingozi empilweni yabantu.

Amasu Okunciphisa

Kusetshenziswa amasu amaningana ukuze kuncishiswe umthelela we-AMD kwezemvelo, okuhlanganisa: Izindlela zokwelapha ezingashintshiwe: Lezi zisebenzisa izinqubo zemvelo, njengamaxhaphozi, ukuze kuncishiswe ubumuncu futhi kukhishwe izinsimbi ezisindayo. Amasistimu okwelapha asebenzayo: Lawa asebenzisa izinqubo zamakhemikhali noma zebhayoloji ukwelapha amanzi ane-asidi ngaphambi kokuba angene endaweni ezungezile. Ukuvimbela ukuchayeka: Ukunciphisa ukuchayeka kwe-pyrite emoyeni nasemanzini ngesikhathi nangemva kwemisebenzi yokumba.

Isiphetho

I-Iron 11 sulfide, nakuba ngokuvamile zinganakwa, zidlala indima ebalulekile ezinqubweni eziningana zezimboni futhi zinemithelela ebalulekile yendawo ezungezile. Ukuqonda izakhiwo zayo kanye nemithelela engaba khona kwezemvelo kubalulekile ekuphathweni kwezinsiza ngendlela efanele kanye nokuvikelwa kwemvelo. Ucwaningo olwengeziwe nokuthuthukiswa kwamasu okunciphisa i-AMD asebenzayo kubalulekile ukuze kuncishiswe imiphumela emibi yezemvelo ehambisana nalesi simbiwa esibalulekile.

Ukuze uthole ulwazi olwengeziwe mayelana nezinto ezisimeme ze-silicon nezisombululo, cabanga ukuhlola umsebenzi omusha owenziwayo I-Inner Mongolia Xinxin Silicon Industry Co.,Ltd. Ukuzibophezela kwabo emikhubeni ebhekele imvelo kuhambisana ngokuphelele nesidingo sezisombululo ezisimeme ezindaweni ezithintwe ukumbiwa nokucutshungulwa kwezimbiwa.
