Iron Sulfidi

Ukuqonda i-Iron sulfide: iiPropati, uLwakhiwo, kunye nosetyenziso

I-Iron sulfide, ikhompawundi eyenzeka ngokwemvelo, ikhona kwiintlobo ezahlukeneyo ezineempawu ezahlukeneyo kunye nokusetyenziswa. Esi sikhokelo sibanzi siphonononga iintlobo ezahlukeneyo ze i-iron sulfide, iinkqubo zabo zokwenza, iimpawu eziphambili, kunye nokusetyenziswa okubalulekileyo kumashishini ahlukeneyo. Siza kugocagoca kubume bekhemikhali, iipropathi zomzimba, kunye nefuthe lokusingqongileyo kule minerali ibalulekileyo.

Iintlobo ze-Iron Sulfidi

IPyrite (FeS₂)

Idla ngokubizwa ngokuba yigolide yesidenge ngenxa yombala wayo otyheli obhedu, ipyrite yeyona ixhaphakileyo i-iron sulfide iminerali. Ngumthombo obalulekileyo wesulfure kwaye ifumaneka rhoqo kumatye e-sedimentary kunye ne-metamorphic. Ubunzima bePyrite kunye nesakhiwo se-cubic crystalline zizinto ezahlukileyo. Ukungazinzi kwayo emoyeni nasemanzini kukhokelela kwi-oxidation, ukuvelisa i-asidi ye-sulfuric - inkqubo enemiphumo yokusingqongileyo exutyushwa kamva. Funda ngakumbi malunga necrystallography yepyrite apha.

I-Pyrrhotite (Fe_1-xS)

I-Pyrrhotite yenye into ebalulekileyo i-iron sulfide iminerali enomxholo wentsimbi eguquguqukayo, emelwe yifomula yeFe_1-xS, apho u-x aqala ku-0 ukuya ku-0.17. Olu tshintsho luchaphazela iimpawu zalo zemagneti, lwenza ezinye iifom zemagneti ngelixa ezinye zingenjalo. Umbala wayo ngokuqhelekileyo umdaka-omnyama okanye ubhedu, kwaye uhlala ufumaneka ngokubambisana nezinye iiminerali ze-sulfide. IPyrrhotite idlala indima ebalulekileyo kwiinkqubo ezithile zejoloji kwaye inokuba ngumthombo oxabisekileyo wentsimbi kunye nesalfure.

Mackinawite (FeS)

IMackinawite, i-ferrous i-iron sulfide, idla ngokufunyanwa njenge-precursor kwezinye ii-sulfide ze-iron, ezenza phantsi kweemeko eziphantsi kweqondo lokushisa. Yiminerali engazinzanga kwaye iguquka ngokukhawuleza ibe ziifom ezizinzileyo njengepyrite phantsi kweemeko ezithile zokwakheka komhlaba kunye nokusingqongileyo. Ukuqonda ukubunjwa kwayo kunceda ekuchazeni iinkqubo ze-sedimentary kunye nokuqikelela ukuziphatha kwentsimbi kwiindawo ezahlukeneyo. Iimpawu zayo ziquka umbala omnyama kunye nesakhiwo se-crystalline hexagonal.

Ukwenziwa kwe-Iron Sulfidi

Iron sulfide iiminerali zenza ngeenkqubo ezahlukeneyo zejoloji. Enye indlela eqhelekileyo ibandakanya ukusabela phakathi kwezisombululo ezinobutyebi bentsimbi kunye neentlobo zesulfure ezinyityilisiweyo (i-hydrogen sulfide, umzekelo) kwiindawo ezingqonge i-anaerobic, ezifana nemigxobhozo, iibhogi, kunye nentlenga enzulu yolwandle. Umsebenzi webhaktheriya unokudlala indima ebalulekileyo kwezi mpendulo, uphembelela okuthe ngqo i-iron sulfide iminerali ehamba phambili. Izintlu zeHydrothermal kumgangatho wolwandle yenye indawo ebalulekileyo i-iron sulfide ukwakheka. Iimeko zeqondo lobushushu, uxinzelelo, kunye nobukho bezinye izinto ziphembelela uhlobo lwe i-iron sulfide yenziwe.

Ukusetyenziswa kwe-Iron Sulfidi

Iron sulfide Iiminerali zinemisebenzi emininzi ebalulekileyo:

Ukuveliswa kweSulfur: I-Pyrite ngumthombo obalulekileyo wesulfure kwishishini lemichiza, elisetyenziselwa ukuveliswa kwe-asidi ye-sulfuric kunye nezinye iikhompawundi ezinesulfure.
Ukuveliswa kwentsimbi: Ngokuqinisekileyo i-iron sulfide iiminerali zilungiswa njengentsimbi ekrwada ukutsala intsimbi. Inkqubo ibandakanya ukususa isulfure, enokuthi ibe yinyathelo elinzima ngenxa yeempembelelo zayo zokusingqongileyo.
Imibala: Ngokwembali, i-iron sulfide isetyenziswe njengebala, nangona ukungazinzi kwayo emoyeni kunciphisa ukusetyenziswa kwayo kwiipeyinti zanamhlanje.
I-Catalysis: Kwezinye iinkqubo ezithile, i-iron sulfides inokusebenza njenge-catalysts kwiikhemikhali ezithile.

Impembelelo yokusingqongileyo

I-oxidation ye i-iron sulfide iiminerali, ngakumbi i-pyrite, inokukhokelela kwi-acid mine drainage (AMD). Le nkqubo ikhupha iasidi yesulfuric kunye nesinyithi esinzima kwindalo esingqongileyo, ibangela ungcoliseko olukhulu lwamanzi nomhlaba. Ukuqonda kunye nokunciphisa i-AMD kubalulekile kulawulo lwemigodi olunenkathalo nobutyebi.

Ukuqukumbela

Iron sulfide ibandakanya iqela leeminerali ezibalulekileyo ezineempawu ezahlukeneyo kunye nokusetyenziswa. Ukusuka kwindima yayo kwiinkqubo zejoloji ukuya kusetyenziso lwayo lwemizi-mveliso, ukuqonda iintlobo ezahlukeneyo, ukwakheka, kunye nefuthe lokusingqongileyo i-iron sulfide ibalulekile kwiinkalo ezahlukeneyo. Uphando olongezelelweyo luyaqhubeka nokucokisa ukuqonda kwethu eli qela lezimbiwa ezibalulekileyo.
