Iron sulfide

Ukuqonda i-Iron sulfide: Izakhiwo, Ukwakhiwa, kanye Nezicelo

I-Iron sulfide, inhlanganisela eyenzeka ngokwemvelo, ikhona ngezindlela ezihlukahlukene ezinezakhiwo ezihlukene kanye nezicelo. Lo mhlahlandlela ophelele uhlola izinhlobo ezahlukene ze i-iron sulfide, izinqubo zabo zokwakheka, izici ezibalulekile, nokusetshenziswa okubalulekile kuzo zonke izimboni ezihlukahlukene. Sizocubungula ukwakheka kwamakhemikhali, izici zomzimba, kanye nemithelela yemvelo yale mineral ebalulekile.

Izinhlobo ze-Iron sulfide

I-Pyrite (FeS₂)

Okuvame ukubizwa ngegolide lesiwula ngenxa yombala ophuzi wethusi, i-pyrite ivame kakhulu i-iron sulfide amaminerali. Iwumthombo obalulekile wesulfure futhi ivame ukutholakala emadwaleni e-sedimentary kanye ne-metamorphic. Ubulukhuni bePyrite kanye nesakhiwo sekristalu eyi-cubic yizici ezihlukile. Ukungaqini kwayo emoyeni nasemanzini kuholela ku-oxidation, ikhiqize i-sulfuric acid - inqubo enemiphumela yemvelo exoxwa kamuva. Funda kabanzi mayelana ne-crystallography ye-pyrite lapha.

I-Pyrrhotite (Fe_1-xS)

I-Pyrrhotite ingenye ebalulekile i-iron sulfide amaminerali anokuqukethwe kwe-iron okuguquguqukayo, emelelwa ifomula ethi Fe_1-xS, lapho u-x esukela ku-0 kuye ku-0.17. Lokhu kuhlukahluka kuthinta izici zayo kazibuthe, okwenza ezinye izinhlobo zibe zikazibuthe kuyilapho ezinye zingekho. Umbala wayo uvame ukuba nsundu-omnyama noma u-bronze, futhi uvame ukutholakala ngokuhambisana namanye amaminerali e-sulfide. I-Pyrrhotite idlala indima ebalulekile ezinqubweni ezithile zokuma komhlaba futhi ingaba umthombo obalulekile wensimbi nesibabule.

I-Mackinawite (FeS)

IMackinawite, insimbi i-iron sulfide, ngokuvamile itholakala njengesandulela kwezinye ze-iron sulfide, ezakha ngaphansi kwezimo eziphansi zokushisa. Iyiminerali engazinzile futhi ishintsha ngokushesha ibe amafomu azinzile njenge-pyrite ngaphansi kwezimo ezithile ze-geological kanye nemvelo. Ukuqonda ukwakheka kwayo kusiza ekuchazeni izinqubo ze-sedimentary kanye nokubikezela ukuziphatha kwensimbi ezindaweni ezihlukahlukene. Izici zayo zihlanganisa umbala omnyama kanye nesakhiwo se-crystalline hexagonal.

Ukwakhiwa kwe-Iron sulfide

Iron sulfide amaminerali akha ngezinqubo ezihlukahlukene ze-geological. Indlela eyodwa evamile ihilela ukusabela phakathi kwezixazululo ezicebile ngensimbi kanye nezinhlobo zesulfure ezincibilikisiwe (isibonelo i-hydrogen sulfide) ezindaweni ezilwa ne-anaerobic, njengamaxhaphozi, izigxobo, kanye nenhlabathi ejulile yolwandle. Umsebenzi wamagciwane ungadlala indima ebalulekile kulokhu kusabela, kube nomthelela othile i-iron sulfide amaminerali akhuphukayo. Ama-Hydrothermal vents at the ocean floor angenye indawo ebalulekile i-iron sulfide ukwakheka. Izimo zezinga lokushisa, ingcindezi, nokuba khona kwezinye izakhi kuthonya uhlobo lwe i-iron sulfide kwakheka.

Izicelo ze-Iron sulfide

Iron sulfide amaminerali anezicelo ezimbalwa ezibalulekile:

Ukukhiqizwa kwesibabule: I-pyrite iwumthombo obalulekile wesibabule embonini yamakhemikhali, esetshenziselwa ukukhiqizwa kwe-sulfuric acid nezinye izinhlanganisela eziqukethe isulfure.
Ukukhiqizwa Kwensimbi: Okuthile i-iron sulfide amaminerali acutshungulwa njengensimbi ukuze kukhishwe insimbi. Le nqubo ihilela ukususa isibabule, okungaba isinyathelo esiyinselele ngenxa yemiphumela yaso yemvelo.
Izingulube: Ngokomlando, i-iron sulfide iye yasetshenziswa njenge-pigment, nakuba ukungazinzi kwayo emoyeni kunciphisa ukusetshenziswa kwayo kopende besimanje.
I-Catalysis: Kwezinye izinhlelo zokusebenza ezithile, ama-iron sulfide angasebenza njengezisusa ekuphenduleni okuthile kwamakhemikhali.

Umthelela Wezemvelo

I-oxidation ye i-iron sulfide amaminerali, ikakhulukazi i-pyrite, angaholela ku-acid mine drainage (AMD). Le nqubo ikhiphela i-sulfuric acid nezinsimbi ezisindayo endaweni ezungezile, okubangela ukungcoliswa okukhulu kwamanzi nomhlabathi. Ukuqonda kanye nokunciphisa i-AMD kubalulekile ekuphathweni kwezimayini nokuphathwa kwezinsiza.

Isiphetho

Iron sulfide ihlanganisa iqembu lamaminerali abalulekile anezakhiwo ezihlukahlukene kanye nezicelo. Kusukela endimeni yayo ezinqubweni zokwakheka komhlaba kuya ekusetshenzisweni kwayo kwezimboni, ukuqonda izinhlobo ezahlukene, ukwakheka, kanye nomthelela wemvelo i-iron sulfide ibalulekile emikhakheni eyahlukene. Ucwaningo olwengeziwe luyaqhubeka nokuthuthukisa ukuqonda kwethu leli qembu lezimbiwa ezibalulekile.
