Iron Pyrite: Ukuntywila nzulu kwiIron(II) SulphideIron(II) sulfide, eyaziwa njenge. intsimbi yepyrite, iyiminerali ekhangayo enoluhlu olubanzi lwezicelo kunye neempawu ezinomdla. Esi sikhokelo sibanzi siphonononga ukwakheka kweekhemikhali, iimpawu zomzimba, ukwakheka, ukusetyenziswa, kunye nefuthe lokusingqongileyo intsimbi yepyrite. Siza kuphonononga ngokubaluleka kwayo kumashishini ahlukeneyo kwaye sixoxe ngendima yayo kwiinkqubo zejoloji.

Ukubunjwa kwemichiza kunye neePropati

Intsimbi yepyrite (FeS?) yiminerali ye-iron sulfide enesakhiwo esikhethekileyo se-cubic crystal. Indlela yayo yeekhemikhali ibonisa umlinganiselo we-1: 2 wentsimbi (II) kwisulfure. Olu qulunqo lukhokelela kwiimpawu ezininzi eziphambili:

Iipropati Zomzimba

Umbala: Ngokuqhelekileyo i-brossy yellow, ihlala inemibala ekhanyayo. Ukuqina: Ubunzima obulinganiselweyo (6-6.5 kwisikali sobulukhuni be-Mohs). Ubunzima obuthile: malunga ne-5.0 g/cm3. Uluhlu: Buluhlaza-mnyama okanye bumdaka-mnyama. I-Cleavage: Cubic, kodwa ihlala ingafezekanga. Ukuqhekeka: Conchoidal.

Iipropati zeMichiza

Intsimbi yepyrite izinzile phantsi kweemeko eziqhelekileyo, kodwa inokusabela ngeoksijini kunye namanzi ukwenza iasidi yesulfuric, inkqubo eyaziwa ngokuba yi-acid mine drainage. Le nkqubo ibalulekile kwiimeko zokusingqongileyo kunye nokusebenza kwemigodi. Ukusabela kuyingozi kakhulu kwaye kunokuvelisa ubushushu obukhulu.

Ukuqulunqwa kunye neZenzeko

Intsimbi yepyrite Iifom kwizicwangciso ezahlukeneyo zejoloji, ngokuyintloko ngeenkqubo ze-hydrothermal, i-sedimentary deposition, kunye nokuguqulwa kwe-metamorphic. Yiminerali eqhelekileyo efumaneka kumatye e-sedimentary, i-igneous rocks, kunye namatye e-metamorphic kwihlabathi jikelele. Iidiphozithi ezibalulekileyo zihlala zinxulunyaniswa nemithungo yamalahle, kwaye ifumaneka rhoqo kwimithambo ye-hydrothermal.

Ukusetyenziswa kwe-Iron pyrite

Ngokwembali, intsimbi yepyrite yaphazama ngegolide (igolide yesidenge), kodwa inezicelo ezininzi ezibalulekileyo:

Izicelo zoShishino

Ukuveliswa kweSulfur: Intsimbi yepyrite ngumthombo obalulekileyo wesulfure kwishishini lemichiza, elisetyenziselwa ukuveliswa kwe-asidi ye-sulfuric, enezicelo ezibanzi. Ukusetyenzwa kwe intsimbi yepyrite ukuvelisa isulfure kubandakanya ukuqhotsa (ukufudumeza xa kukho umoya). Ukuveliswa kwentsimbi: Nangona kunqabile, intsimbi yepyrite inokusetyenziswa njengomthombo wentsimbi, nangona ezinye iintsimbi zentsimbi zisebenza kakuhle.

Okunye Ukusetyenziswa

Imibala: Umhlaba ocolekileyo intsimbi yepyrite isetyenziswe ngokwembali njengebala. Iinjongo zokuhombisa: Inkangeleko yayo enomtsalane iyenza ilungele ukusetyenziswa kubucwebe, nangona ubunzima bayo obuphantsi buthetha ukuba ifaneleke kakhulu kwizinto ezinganxitywanga.

Impembelelo yokusingqongileyo

I-oxidation ye intsimbi yepyrite, ngakumbi kwimisebenzi yemigodi, kunokukhokelela kwiingxaki ezibalulekileyo zokusingqongileyo. I-Acid mine drainage (AMD) ephuma kolu hlaselo ingcolisa iindlela zamanzi, yenzakalise ubomi basemanzini kunye ne-ecosystem. Amaqhinga asebenzayo olawulo lokukhupha amanzi emigodini abalulekile ekudambiseni impembelelo yokusingqongileyo intsimbi yepyrite i-oxidation.

Uphononongo oluNgakumbi

Ukufunda ngakumbi malunga nokugcinwa kwemigodi kunye nokulungiswa kwezimbiwa ezifana intsimbi yepyrite, phonononga izixhobo ezivela kwimibutho ezinikele kuxanduva lokusingqongileyo kwishishini lemigodi. Ngolwazi malunga nezicelo ezithile okanye iipropathi zekhemikhali, jonga kuluhlu lweenkcukacha zenzululwazi kunye noshicilelo.
