Kev kho mob ntawm zinc slag tuaj yeem muab faib ua ob txoj hauv kev tseem ceeb: txheej txheem ntub dej thiab txheej txheem pyrometallurgical. Lub hauv paus ntawm cov txheej txheem pyrometallurgical yog distillation. Nyob ntawm cov khoom siv distillation siv, nws tuaj yeem muab faib ntxiv rau hauv kab rov tav tank distillation, kab-frequency coreless induction rauv distillation, arc rauv distillation, thiab txuas ntxiv distillation furnace distillation. Cov khoom siv distillation tuaj yeem yog hlau zinc, zinc hmoov, lossis zinc oxide zoo dua, nyob ntawm qhov xav tau. Kab rov tav tank distillation rau kev kho mob ntawm kub-dip galvanizing zinc slag qhia tib yam zoo thiab qhov tsis zoo raws li kab rov tav tank distillation rau kev kho mob ntawm kub-dip galvanizing zinc tshauv. Kev siv cov kab ntau zaus coreless induction furnaces thiab arc furnaces rau kev kho mob ntawm kub-dip galvanizing pov tseg slag yog tam sim no txwv ntawm manufacturers vim cov cuab yeej siv siab, tsis tshua muaj peev xwm ntau lawm, complex condenser xaiv, thiab tsis zoo condensation efficiency. Tsis tas li ntawd, lub hauv paus dispersed ntawm zinc slag ua rau nws nyuaj rau sau. Ntawm qhov tod tes, lub qhov cub tawg tas li yog ib yam tshiab ntawm lub qhov cub tshwj xeeb tsim los rau kev kho mob kub-dip galvanizing pov tseg slag. Nws tag nrho overcomes lub discontinuity ntawm lwm cov txheej txheem pyrometallurgical rau kev kho kub-dip galvanizing pov tseg slag, enabling nruam ntau lawm. Ntxiv mus, nws boasts ib tug siab zinc rov qab tus nqi, saj zawg zog cov cuab yeej ua muaj peev xwm, tsawg cov cuab yeej siv, thiab txo zog siv piv rau kab rov tav tank distillation, ua rau nws nrov ntawm cov tuam txhab uas muag tshwj xeeb hauv zinc slag kev kho mob thiab yog li dav siv.
Cov txheej txheem ntub dej rau kev kho kub-dip galvanizing pov tseg slag tuaj yeem muab faib ua ob txoj kev sib txawv raws li cov khoom tau txais. Thawj yog cov txheej txheem soluble anode electrolysis, qhov twg cov khib nyiab pov tseg yog cam khwb cia lossis tuag-cam khwb cia rau hauv ib qho anode, nrog ib lub phaj txhuas raws li cathode thiab aqueous tov ntawm sulfuric acid los yog sulfuric acid esters li electrolyte. Nyob rau hauv qhov kev txiav txim ntawm ncaj qha tam sim no, lub anode tsis tu ncua dissolves, thiab zinc precipitates tawm ntawm lub cathode, thaum kawg tsim electrolytic zinc. Qhov zoo ntawm txoj kev no suav nrog cov zinc rov qab siab. Txawm li cas los xij, qhov teeb meem loj yog qhov nrawm nrawm ntawm cov hlau hauv electrolyte, uas nyuaj rau tshem tawm, yog li txwv nws cov ntawv thov kev lag luam. Lwm txoj kev yog kev tsim cov zinc sulfate heptahydrate. Txoj kev no suav nrog kev ua kom cov zinc slag nyob rau hauv cov tshuaj aqueous sulfuric acid, tshem tawm cov impurities xws li hlau, thiab tom qab ntawd ua kom pom tseeb thiab crystallizing cov tshuaj aqueous zinc sulfate kom tau txais zinc sulfate heptahydrate.
