Lub luag haujlwm tseem ceeb ntawm zinc sulfate hauv cov txheej txheem ntxhia yog kom xaiv zinc ees thiab tiv taus zinc-muaj cov minerals. Feem ntau, nws tau zoo tsis kam nyob rau hauv alkaline slurry. Qhov siab dua tus nqi ntawm cov slurry, qhov pom tseeb tshaj qhov tiv taus yog, uas tau txais txiaj ntsig rau cov ntxhia ua. Nws tseem yog ib qho siv tau siv cov khoom siv tsis tau nrog cov nqi qis thiab cov nyhuv zoo. Nws yog cov ntaub ntawv tseem ceeb hauv kev ua cov ntxhia.
Lub hauv paus ntsiab lus ntawm zinc sulfate: ntshiab zinc sulfate yog dawb crystal, yooj yim soluble hauv dej sphalerite. Nws feem ntau tsuas yog muaj inhibitis nyhuv hauv alkaline slurry. Qhov siab tshaj li cov pH ntawm slurry, qhov pom tseeb ntau dua nws txoj hauv kev tiv thaiv. Cov. Zinc Sulfate ua cov tshuaj tiv thaiv hauv qab no hauv dej:
ZSO4 = ZN2 ++ so42-
ZN2 ++ 2H20 = ZN (Huag) 2 + 2h +
ZN (Huag) 2 yog ib qho amphoteric compound uas yaj hauv acid los ua ntsev.
ZN (Huag) 2 + h2s04 = Zso4 + 2h2o
Hauv nruab nrab alkaline, hzno2- thiab zno22- tau txais. Lawv adsorption rau cov ntxhia kom txhim kho lub hydrophilicity ntawm cov ntxhia npoo.
ZN (Huag) 2 + NAOH = Nahzno2 + H2O
ZN (Huag) 2 + 2NNOH = NA2ZNO2 + 2H2O
