Lub ntim ntawm zinc sulfate heptahydrate feem ntau muaj ob txheej ntim nrog ib txheej yas sab hauv thiab txheej txheej braided. Tus qauv nqa hnyav yog 25 kg ib lub hnab. Nws yog ib qho tseem ceeb tshaj plaws uas yuav tsum tau ceev faj thaum thauj lub thawv kom tiv thaiv kom tsis txhob tawg, tawg, lossis poob, uas tuaj yeem ua rau muaj kev puas tsuaj. Tsis tas li ntawd, nws yog ib qho tsim nyog yuav tsum tsis txhob sib tov lub thawv nrog oxidants thiab edible chemicals, nrog rau lwm yam khoom. Nws yog ib qho tsim nyog yuav tsum tau tiv thaiv cov khoom los ntawm kev raug tshav ntuj, nag lossis daus, thiab kub siab.

Hais txog kev nyab xeeb, zinc sulfate heptahydrate tau pom tias ua rau mob me ntsis rau lub qhov muag tab sis tsis ua rau tawv nqaij. Kev siv cov tshuaj no tsis raug tuaj yeem ua rau muaj ntau yam tsis zoo, nrog rau xeev siab, ntuav, tsis xis nyob hauv plab, raws plab thiab lwm yam tsos mob ntawm mob plab hnyuv. Hauv cov xwm txheej hnyav dua, nws tuaj yeem ua rau lub cev qhuav dej, poob siab thiab, hauv qhov xwm txheej hnyav, txawm tias tuag. Cov khoom no muaj kev phom sij rau ib puag ncig thiab muaj peev xwm ua rau muaj kuab paug hauv dej. Kev npaj ntawm zinc sulfate heptahydrate tuaj yeem ua tiav los ntawm kev tsim cov khoom siv los ntawm zinc rhodochrosite, sphalerite, thiab lwm yam khoom siv raw, lossis los ntawm kev siv cov kua khib nyiab ntawm zinc sulfate. Thaum lub sij hawm tsim khoom, feem ntau ntawm anionic thiab xaiv cationic impurities tuaj yeem raug tshem tawm los ntawm crystallisation, uas ua rau tsim cov khoom nrog ntxhib nplej.
