Iron sulfide

Kunzwisisa Iron sulfide: Zvivakwa, Maumbirwo, uye Zvishandiso

Iron sulfide, musanganiswa unongoitika, uripo mumhando dzakasiyana siyana zvine zvimiro uye mashandisirwo akasiyana. Gwaro iri rakazara rinoongorora mhando dzakasiyana dze iron sulfide, maitiro avo ekugadzira, maitiro akakosha, uye mashandisiro akakosha mumaindasitiri akasiyana siyana. Isu tichaongorora mukugadzirwa kwemakemikari, zvimiro zvemuviri, uye zvakatipoteredza zvine chekuita neiyi yakakosha mineral.

Mhando dzeIron sulfide

Pyrite (FeS₂)

Inowanzonzi goridhe rebenzi nekuda kwebrossy yellow color, pyrite ndiyo inonyanya kuzivikanwa iron sulfide mineral. Iyo yakakosha sosi yesarufa uye inowanzowanikwa mune sedimentary uye metamorphic matombo. Kuoma kwePyrite uye cubic crystalline chimiro zvinhu zvakasiyana. Kusagadzikana kwaro mumhepo nemvura kunotungamirira kune oxidation, kubudisa sulfuric acid - nzira ine migumisiro yezvakatipoteredza inokurukurwa gare gare. Dzidza zvakawanda nezve pyrite's crystallography pano.

Pyrrhotite (Fe_1-xS)

Pyrrhotite imwe inokosha iron sulfide mineral ine inosiyana iron content, inomiririrwa neformula Fe_1-xS, apo x inotangira pa0 kusvika pa0.17. Kusiyana uku kunokanganisa maitiro ayo emagetsi, zvichiita mamwe magineti asi mamwe asina. Muvara waro unowanzo kusviba-dema kana bhuronzi, uye inowanzowanikwa mukubatana nemamwe maminerari e sulfide. Pyrrhotite inotora basa rakakosha mune mamwe maitiro ejoloji uye inogona kuve yakakosha sosi yesimbi nesarufa.

Mackinawite (FeS)

Mackinawite, ane ferrous iron sulfide, inowanzowanikwa sechinhu chinotangira kune mamwe iron sulfides, inoumba pasi pemamiriro ekupisa. Iyo ine mineral isina kugadzikana uye inokurumidza kushandura kuita yakagadzikana mafomu senge pyrite pasi pemamwe mamiriro e geological uye ezvakatipoteredza. Kunzwisisa kuumbwa kwayo kunobatsira mukududzira sedimentary maitiro uye kufanotaura maitiro esimbi munzvimbo dzakasiyana siyana. Hunhu hwayo hunosanganisira ruvara rwakasviba uye hexagonal crystalline chimiro.

Kugadzirwa kweIron sulfide

Iron sulfide zvicherwa zvinoumba kuburikidza neakasiyana geological process. Imwe nzira yakajairika inosanganisira kuita pakati pemhinduro dzesimbi-yakapfuma uye yakanyungudika sarufa marudzi (hydrogen sulfide, semuenzaniso) munzvimbo dzeanaerobic, senge machakwi, mabhogi, uye yakadzika yegungwa sediments. Basa rebhakitiriya rinogona kuita basa rakakosha mune izvi maitiro, zvichikurudzira izvo chaizvo iron sulfide mineral inonaya. Hydrothermal vents pasi pegungwa ndiyo imwe nzvimbo yakakosha iron sulfide kuumbwa. Mamiriro ekushisa, kumanikidzwa, uye kuvapo kwezvimwe zvinhu zvinopesvedzera rudzi rwe iron sulfide akaumbwa.

Zvishandiso zveIron sulfide

Iron sulfide minerals ine akati wandei akakosha maapplication:

Kugadzirwa kweSulfur: Pyrite inzvimbo yakakosha yesarufa yeindasitiri yemakemikari, inoshandiswa mukugadzira sulfuric acid uye mamwe macompound ane sulfur.
Kugadzirwa Kwesimbi: Chokwadi iron sulfide zvicherwa zvinogadzikiswa sesimbi yekuchera simbi. Nzira yacho inosanganisira kubvisa sarufa, iyo inogona kuva nhanho yakaoma nekuda kwezvakatipoteredza.
Pigments: Nhoroondo, iron sulfide yakashandiswa se pigment, kunyange zvazvo kusagadzikana kwayo mumhepo kunoderedza kushandiswa kwayo mumapendi emazuva ano.
Catalysis: Mune mamwe mashandisirwo chaiwo, iron sulfides inogona kuita senge inokonzeresa mune mamwe maitiro emakemikari.

Environmental Impact

Iyo oxidation ye iron sulfide zvicherwa, kunyanya pyrite, zvinogona kutungamirira kune acid mine drainage (AMD). Kuita uku kunoburitsa sulfuric acid nesimbi inorema mukati menharaunda, zvichikonzera kusvibiswa kukuru kwemitumbi yemvura nevhu. Kunzwisisa uye kudzikisira AMD kwakakosha kune zvine chekuita nemigodhi uye manejimendi zviwanikwa.

Mhedziso

Iron sulfide rinobatanidza boka remaminerari akakosha ane zvinhu zvakasiyana siyana uye mashandisirwo. Kubva pakuita kwayo mu geological process kusvika kune yayo maindasitiri mashandisiro, kunzwisisa akasiyana marudzi, kuumbwa, uye kwezvakatipoteredza kukanganisa kwe iron sulfide yakakosha munzvimbo dzakasiyana siyana. Kumwe kutsvagurudza kunoenderera mberi nekunatsa manzwisisiro edu eiyi yakakosha mineral boka.
