I-Iron Pyrite (Iron 11 Sulfidi): I-Comprehensive GuideIron pyrite, ekwaziwa njengegolide yesidenge, sisimbiwa sendalo esinendalo esiqulunqwe ikakhulu intsimbi 11 sulfide (FeS?). Esi sikhokelo sinikezela ngenkcazo eneenkcukacha malunga neempawu zayo, usetyenziso, kunye nokubaluleka kokusingqongileyo.

IiPropati zeMzimba kunye nezeMichiza ye-Iron Pyrite

Iron 11 sulfide ibonakala ngombala wayo owahlukileyo we-brassy-yellow kunye nokucwebezela kwesinyithi. Ukuqina kwayo yi-6-6.5 kwisikali se-Mohs, okuthetha ukuba inzima kwaye iyamelana nokukrwela. Ngokomchiza, yi-iron sulfide, ebonakala ngokulula ngesakhiwo sayo sekyubhiki yekristale. Ayinakusebenza kangako phantsi kweemeko eziqhelekileyo zomoya kodwa inokusabela ngeoksijini kunye namanzi ukwenza iasidi yesulfuric, inkqubo eyaziwa ngokuba yi-acid mine drainage, esiza kuyixoxa kamva. Ukwakhiwa kweekhemikhali ngokuthe ngqo kunokwahluka kancinane ngokuxhomekeke kwindawo kunye neemeko zejoloji eyakhiwe phantsi kwayo. Okunye ukungcola kunokubandakanya i-arsenic, i-cobalt, okanye i-nickel.

Ukuchonga Iron Pyrite

Ukwahlula intsimbi 11 sulfide ukusuka kwigolide yokwenene kufuna ukuqwalaselwa ngenyameko. Ngelixa ifana ngombala, i-pyrite iqhelekile kwaye iya kushiya umnyama omnyama-omnyama xa ukhuhlwe kwindawo eqinileyo, ngokungafaniyo negolide, eshiya igolide. Uvavanyo olulula lweasidi lunokuqinisekisa nokuba lungubani. I-Pyrite iya kusabela nge-acids eqinile, ivelise igesi ye-hydrogen sulfide, enempawu yeqanda elivumba elibi.

Ukusetyenziswa kwe-Iron Pyrite

Ngokwembali, intsimbi 11 sulfide ibe ngumthombo obalulekileyo wentsimbi nesalfure. Ngelixa ukusetyenziswa kwayo njengomthombo wentsimbi ngokuthe ngqo kuye kwehlile ngenxa yokufumaneka kwe-ores ephezulu, ihlala ibalulekile kwiinkqubo ezininzi zoshishino:

1. Ukuveliswa kwe-Acid ye-Sulfuri

Olona setyenziso lubalulekileyo lwe intsimbi 11 sulfide ikwimveliso ye-asidi yesulfuric (H?SO?). Ngenkqubo ebizwa ngokuba yi-roasting, ipyrite ifudunyezwa kubukho bomoya, iguqule isulfure kwi-sulphur dioxide (SO?), ethi emva koko isetyenziswe ukuvelisa iasidi yesulfuric. Le nkqubo ibalulekile kwimizi-mveliso emininzi, kuquka isichumiso, imichiza kunye nemveliso yesinyithi.

2. Ezinye izicelo

Izixa ezincinci ze intsimbi 11 sulfide zisetyenziselwa ukuveliswa kwee-pigments, njengomthombo wesulfure kwezinye iinkqubo ze-metallurgical, kunye nokuveliswa kweentlobo ezithile zekhonkrithi.

Iingqwalasela zokusiNgqongileyo: IMibhobho ye-Acidi yoMbhobho

I-oxidation ye intsimbi 11 sulfide, ngokukodwa kumxholo wemigodi, kunokukhokelela kwingxaki ebalulekileyo yokusingqongileyo: i-acid mine drainage (AMD). Xa ibonakaliswe emoyeni nasemanzini, i-pyrite iphendula ukwenza i-asidi ye-sulfuric, enokuthi ikhuphe isinyithi esinzima kumatye ajikelezileyo kwaye ingcolise imithombo yamanzi. Oku kubaleka kuneasidi kunokuba neziphumo ezibi kwi-ikhosistim yasemanzini kwaye kubeka imingcipheko kwimpilo yabantu.

Amaqhinga okunciphisa

Amaqhinga amaninzi asetyenzisiweyo ukunciphisa ifuthe le-AMD kokusingqongileyo, kubandakanywa: Iinkqubo zonyango ezinganyangekiyo: Ezi zisebenzisa iinkqubo zendalo, ezifana nemigxobhozo, ukuthomalalisa ubumuncu kunye nokususa iintsimbi ezinzima. Iinkqubo zonyango ezisebenzayo: Ezi zisebenzisa iinkqubo zekhemikhali okanye zebhayoloji ukunyanga amanzi aneasidi ngaphambi kokuba angene kwindawo esingqongileyo. Ukuthintela ukuba sesichengeni: Ukunciphisa ukuba sesichengeni sepyrite emoyeni nasemanzini ngexesha nasemva kwemisebenzi yemigodi.

Ukuqukumbela

Iron 11 sulfide, nangona isoloko ingahoywa, idlala indima ebalulekileyo kwiinkqubo ezininzi zemizi-mveliso kwaye ineempembelelo ezibalulekileyo zokusingqongileyo. Ukuqonda iipropathi zayo kunye neempembelelo ezinokuthi zibe kho kokusingqongileyo kubalulekile kulawulo olunenkathalo lobutyebi kunye nokukhuselwa kokusingqongileyo. Uphando olongezelelweyo nophuhliso lwezicwangciso-qhinga zokunciphisa i-AMD zibalulekile ukunciphisa iziphumo ezibi kokusingqongileyo ezinxulumene nesi simbiwa sibalulekileyo.

Ngolwazi oluthe kratya malunga nezixhobo zesilicon ezizinzileyo kunye nezisombululo, cinga ngokuphonononga umsebenzi owenziweyo I-Inner Mongolia i-Xinxin Silicon Industry Co.,Ltd. Ukuzinikela kwabo kwimisebenzi enoxanduva lokusingqongileyo kuhambelana ngokugqibeleleyo nemfuno yezisombululo ezizinzileyo kwiindawo ezichatshazelwa kukutsalwa kwezimbiwa kunye nokusetyenzwa kwazo.
