Txoj kev kho mob rau Zinc tshauv tuaj yeem muab faib ua cov txheej txheem ntub thiab pyrometallurgical. Cov txheej txheem pyrometallurgical, tseem hu ua distillation, muaj kev haus kom cov boiling points ntawm lwm cov impurities hauv cov tshauv. Nyob rau hauv ib txwm siab thiab siab kub, zinc yog volatilized rau Zinc Vapor, lossis cov zinc av tshauv tau raug txo mus rau zinc vapor, uas yog tom qab ntawd condensed rau hauv cov kua hlau zinc lossis zinc. Lwm cov metallic impurities nyob rau hauv cov seem. Tam sim no, cov khoom siv distillation ntau zaus rau cov qauv no yog kab rov tav. Tus qauv kab rov tav distillation txoj kev rau zinc extraction yog cov txheej txheem txheej thaum ub. Nyob rau hauv cov nqe lus ntawm kev kho zinc tshauv, nws muaj qhov zoo ntawm cov peev txheej qis, cov txheej txheem yooj yim, thiab ntau yam kev ua siab ntev rau imprity muaj pes tsawg leeg thiab zinc cov ntsiab lus. Txawm li cas los xij, nws tseem muaj qhov tsis tseem ceeb, suav nrog kev siv dag zog siab, siv hluav taws xob siab, muaj peev xwm ua tau muaj peev xwm tsawg. Raws li tib neeg xav tau ib puag ncig zoo dua qub, cov qauv no ntawm kev kho zinc tshauv yuav phased tawm.
Ntub zinc SMELTING yog tam sim no lub ntsiab txuj kev nthuav dav tseem ceeb hauv kev lag luam zinc smelting. Kev sim kev sim thiab kev tshawb fawb tau ua rau kev siv cov txheej txheej ntub los kho zinc tshauv, thiab kev nce qib tseem ceeb tau ua. Cov txheej txheem kev kho mob no muaj cov kauj ruam xws li dej dej kub ua si, tsis muaj leaching, thiab cov kua qaub kub ntawm zinc. Cov dej dej kub ua pauj kom loj dua ntawm cov pa roj carbon hauv zinc tshauv, txo lub nra ntawm chloride ion tshem tawm hauv cov txheej txheem tom ntej. Cov hom phiaj tsis pub muaj txiaj ntsig kom tau txais cov electrolyte uas tau ntsib cov kev yuav tsum electrolysis yuav tsum tau. Cov kua qaub kub kua qaub rau lub hom phiaj kom ua kom tiav ntawm kev ua si ntawm zinc rau hauv kev daws. Cov kev sim tau qhia tias txoj kev no tuaj yeem ua tiav tus nqi siab dua 97%, thiab yuav luag tsis muaj kev phom sij yog tsim tawm thaum cov txheej txheem. Nws yog cov qauv kev cog lus nrog kev txhim kho kev nyab xeeb zoo.
