Iron Pyrite (Iron 11 Sulfidi): A Comprehensive GuideIron pyrite, inozivikanwawo segoridhe rebenzi, iminerari inowanzoitika inoumbwa kunyanya iron 11 sulfide (FeS?). Gwaro iri rinopa tarisiro yakadzama yezvivakwa zvayo, mashandisirwo, uye kukosha kwezvakatipoteredza.

Zvenyama uye Kemikari Zvivakwa zveIron Pyrite

Iron 11 sulfide inoratidzirwa neyakasiyana-siyana yebrassy-yellow ruvara uye metallic luster. Kuomarara kwayo ndeye 6-6.5 pachiyero cheMohs, zvichireva kuti yakaoma uye inoshingirira kukwenya. Kemikari, isimbi sulfide, ino zivikanwa nyore kuburikidza ne cubic crystal chimiro. Inenge isingaite basa pasi pemamiriro ekunze emuchadenga asi inogona kuita neokisijeni nemvura kuita sulfuric acid, nzira inozivikanwa seacid mine drainage, yatichakurukura gare gare. Iyo chaiyo kemikari inoumbwa inogona kusiyanisa zvishoma zvichienderana nenzvimbo uye geological mamiriro ayo akaumba. Kumwe kusvibiswa kunogona kusanganisira arsenic, cobalt, kana nickel.

Kuziva Iron Pyrite

Kusiyanisa iron 11 sulfide kubva kugoridhe chaiyo kunoda kunyatsocherechedza. Kunyange zvazvo yakafanana nemuvara, pyrite inowanzoita brittle uye inosiya rima rakasvibirira-dema streak kana yakakwizwa pamusoro penzvimbo yakaoma, kusiyana negoridhe, iyo inosiya goridhe streak. A simple acid test inogonawo kusimbisa huzivi hwayo. Pyrite ichaita neakasimba acids, ichigadzira hydrogen sulfide gasi, iyo ine hunhu hwakaora zai hwema.

Zvishandiso zveIron Pyrite

Nhoroondo, iron 11 sulfide kwave kuri manyuko makuru esimbi nesarufa. Nepo kushandiswa kwayo seyakananga simbi sosi kwadzikira nekuda kwekuwanikwa kwepamusoro-giredhi ores, inoramba yakakosha mune akati wandei maindasitiri maitiro:

1. Sulfuric Acid Production

Kunyanya kukosha kwekushandisa kwe iron 11 sulfide iri mukugadzira sulfuric acid (H.SO?). Kuburikidza nenzira inonzi kugocha, pyrite inopisa pamberi pemhepo, ichishandura sarufa kuva sulfur dioxide (SO?), iyo inoshandiswa kugadzira sulfuric acid. Iyi nzira yakakosha kune akawanda maindasitiri, anosanganisira fetereza, makemikari, uye kugadzirwa kwesimbi.

2. Zvimwe Zvikumbiro

Zvishoma zvishoma zve iron 11 sulfide anoshandiswa mukugadzira pigment, sechitubu chesarufa kune mamwe mametallurgical process, uye mukugadzira mamwe marudzi ekongiri.

Mafungiro Ezvakatipoteredza: Acid Mine Drainage

Iyo oxidation ye iron 11 sulfide, kunyanya mumamiriro ekuchera, zvinogona kutungamirira kune dambudziko guru rezvakatipoteredza: acid mine drainage (AMD). Kana yaiswa kumhepo nemvura, pyrite inobata kuumba sulfuric acid, iyo inogona kudonhedza masimbi anorema kubva pamatombo akatenderedza uye kusvibisa zvitubu zvemvura. Uku kuyerera kwe acidic kunogona kuve nemhedzisiro inoparadza pazvipenyu zvemumvura uye kunoisa njodzi kuhutano hwevanhu.

Mitigation Strategies

Matanho akati wandei anoshandiswa kudzikisira kukanganiswa kwezvakatipoteredza kwe AMD, kusanganisira: Passive kurapwa masisitimu: Aya anoshandisa maitiro echisikigo, senge manyoro, kudzikamisa acidity uye kubvisa zvinorema simbi. Active kurapwa masisitimu: Aya anoshandisa makemikari kana zvipenyu maitiro kurapa iyo acidic mvura isati yapinda munharaunda. Kudzivirira kuratidzwa: Kuderedza kuratidzwa kwepyrite kumhepo nemvura panguva uye mushure mekuita kwemigodhi.

Mhedziso

Iron 11 sulfide, nepo kazhinji isingatarisirwi, inoita basa rakakosha mumaindasitiri akati wandei uye ine zvakakosha zvakatipoteredza. Kunzwisisa zvimiro zvayo uye zvinogona kukanganisa zvakatipoteredza kwakakosha pakutarisira zviwanikwa zvekuchengetedza uye kuchengetedza kwezvakatipoteredza. Kuwedzera kutsvagisa uye kuvandudzwa kweanoshanda AMD kuderedza nzira kwakakosha kudzikisa kuipa kwakashata mhedzisiro ine chekuita neiyi yakakosha mineral.

Kuti uwane rumwe ruzivo nezve inoenderera nesilicon zvinhu uye mhinduro, funga kuongorora basa rekuvandudza riri kuitwa Inner Mongolia Xinxin Silicon Industry Co., Ltd. Kuzvipira kwavo kumaitiro ane chekuita nemhoteredzo kunopindirana zvakakwana nekudiwa kwemhinduro dzakasimba munzvimbo dzakakanganiswa nekutorwa kwemaminerari uye kugadzirisa.
