Pyrite kaJohn iveliswa kumazwe amaninzi

Pyrite - igama leqela kwezimbiwa, ezo iikhompawundi zesinyithi ukusuka kwiqela tin, nickel, intsimbi, ayibe, platinum. Ezi zinto zingaba isalfure iarseniki, kunye kwistibhiya-selenium okanye.

Calcination pyrite kubonisa ukuba feedstock kukukhanya ngombala, ayenechaphothi sisinyithi, buguqulwe ubungwanyalala ukususela-3 ukuya 7. zentsimbi okanye pyrite yentsimbi (FeS2 formula), eyaziwa ngokuba pyrite, yinto izinto ezixabisekileyo mveliso ekrwada ukusuka apho sulphur dioxide (eziseleni zemveliso). Ngembonakalo, izimbiwa kukho ubunzima ziikristale encinane elichanekileyo bulubhelu izimvi ngebala kunye yobulukhuni 6-6.5. Ukwakhiwa pyrite ecocekileyo ngu 47 yentsimbi ekhulwini yaye malunga 53 ekhulwini nesalfure.

pyrites Calcination sikhatshwe enkalweni eziliqela ekudibaneni kwemichiza, owokuqala leyo obonelela ukwandiswa emanzini izimbiwa intsimbi kunye nesalfa kunyuka karhulumente (ubushushu malunga 500 C). Ke umphunga sulphur kukho combusted, enika sulphur dioxide, kunye oxide zentsimbi okanye emanzini unika oxide mixed. Enigcoba sulphide uyaphakama ngokupheleleyo, wakha 'isibane, "nto leyo iquka izinto fayalite kunye namanye, kuxhomekeke ubumdaka kwi feedstock.

pyrites Calcination inokuvelisa kwisigaba igesi umlinganiselo othile SO3, admixed kunye SO2. Le into enza izinto ngendlela umhlwa izixhobo, ngoko ukunciphisa ubushushu esisi SO3 ngamashishini kwezixhobo iziko kufuneka lube 850S, uze ngokukhawuleza angehla 400C.

pyrite kaJohn kwenziwa kumazwe amaninzi, njengokuba Le nto eyingxenye eqhelekileyo. ERashiya, le izimbiwa nto geni kwilizwe Soymenskoy, Kalitvinskom entsimini, malunga Kushva, izityalo ubufundisi eCaucasus, kwi Ryazan kunye ESmolensk imimandla, kwaye kwezinye iindawo. Phesheya, iidipozithi Spanish ingakumbi odumileyo (ingakumbi Aguas Tenidas apho izinto ayiqulathanga ubhedu, kodwa a sulphur ephakamileyo) ngakumbi kakubi kuphuhliso i-US, France, Norway, Sweden. pyrites sulphuric yendalo iya kuhlala admixed iintlobo iarseniki ukwimo, nto leyo inika ukungcola yingozi kakhulu ekuveliseni iiseli. Ngoko ke, abenzi zama ukusebenzisa izinto ehlambulukileyo ekrwada. Umzekelo, ezi mveliso Russian eSt Petersburg, esebenza pyrites Swedish.

KaJohn of pyrites yentsimbi (nesalfure) senziwe ende yamaziko, apho izinto ekrwada ukudla jija okanye umlomo. Ngaphezu koko, idityaniswe ubunzima kwezinto eziqinileyo esele ngokomyinge (kwibhedi fluidized kwi nothango lwaso, phantsi apho umoya nakwesiphi ukusuka ngezantsi), emva koko kubakho ekudibaneni kwemichiza, enika igesi (isuswe) kunye ikhandlela (wathulula imibhobho inxenye ezizodwa). Kwakhona ezikweni ubushushu obugqithisileyo asuswe izinto olupholisa ngamanzi.

Calcination pyrite iya kuba nempumelelo xa ujongise kunye feed umoya eliphezulu ngokwaneleyo. Ngoko ke, lo izimbiwa ngokufuthi hlulwa zibe kwimeko ungacolwanga (in amaziko afanelekileyo), xa ubukhulu yamasuntswana incinane kangangokuba ioksijini ngokulula ingena ngaphakathi ubunzima kweziyobisi. Ukongeza, ulawulo lobushushu kubalulekile kuba minerals kule klasi basoloko sintered kwiqondo lobushushu ngentla 900 C. Ukuze zokusombulula le ngxaki isetyenziswe processing uthuli-komoya, nto leyo evumela ukuqala izinto kutsha kwiqondo lobushushu ukuya ku-1000 C, nto leyo kuphucula impumelelo yemveliso.
