Lub luag haujlwm tseem ceeb ntawm zinc sulfate hauv kev ua cov ntxhia yog xaiv cov zinc ores thiab tiv thaiv zinc-muaj cov zaub mov.Feem ntau, nws muaj kev ua haujlwm zoo dua hauv alkaline slurry.Qhov siab dua pH tus nqi ntawm slurry, qhov pom tseeb dua qhov tsis kam, uas yog qhov zoo rau kev ua cov ntxhia.Nws kuj yog ib qho khoom siv ntxhia ua khoom siv nrog tus nqi qis thiab cov txiaj ntsig zoo.Nws yog cov khoom siv tseem ceeb hauv kev ua cov ntxhia.
Lub hauv paus ntsiab lus ntawm kev ua ntawm zinc sulfate: Ntshiab zinc sulfate yog dawb siv lead ua, yooj yim soluble hauv dej, thiab yog ib qho inhibitor ntawm sphalerite.Nws feem ntau tsuas muaj cov nyhuv inhibitory hauv alkaline slurry.Qhov siab dua pH ntawm slurry, qhov pom tseeb dua nws cov nyhuv inhibitory..Zinc sulfate tsim cov tshuaj tiv thaiv hauv qab no hauv dej:
ZnSO4＝Zn2++ SO42-
Zn2+2H20=Zn(OH)2+2H+
Zn (OH) 2 yog ib qho amphoteric compound uas yaj hauv cov kua qaub los ua ntsev.
Zn(OH) 2+H2S04＝ZnSO4+2H2O
Hauv nruab nrab alkaline, HZnO2- thiab ZnO22- tau txais.Lawv adsorption rau cov ntxhia pob zeb ua kom cov hydrophilicity ntawm cov pob zeb hauv av.
Zn(OH)2+NaOH=NaHZnO2+H2O
Zn(OH)2+2NaOH=Na2ZnO2+2H2O
