I-Zinc Sulfate Shiptahydrate ibizwa nangokuthi uZinc Vitriol no-Alum Vitriol. I-Molecular Mass yayo efana ne-287.56. Ukubukeka kwayo kuyizinhlayiya ezimhlophe noma i-powder. Kungokwama-OrthorHmbic Crystal System futhi nobuningi bayo obuhlobene ngu-1.97. Kancane kancane izimomo zomoya owomile. Izindlela zokukhiqiza eziphambili zifaka indlela ye-sulfuric acid kanye ne-smithsonite indlela.
Indlela ye-Sulfuric Acid isetshenziselwa ukukhiqiza i-zinc sulfate heptahydrate, esebenzisa i-sulfuric acid ukuncibilikisa izinto ezahlukahlukene eziqukethe i-zinc noma i-zinc onide, izinto ezisele ezivela embonini yensimbi kanye ne- Umkhakha we-metrong we-ferrous, kanye ne-zinc slag kanye nezimayini ze-zinc, njll.
Izinto eziqukethe izidakamizwa zichotshozwa yi-ball mill futhi zichithwe ngo-18% kuya ku-25% sulfuric acid. Ukuchithwa kwenziwa ku-kettle yokuphendula efakwe ezintweni ezilwa nokungamelana ne-acid, njengokuhola, futhi kuhlome ngesikhonzi. Ifomula yokuphendula imi kanjena:
ZN + H2O4 → ZNSO4 znso4 + H2 ↑ ZNO + H2SO4 → ZNSO4 + H2O
Ukuphendula kuyindlela ephakeme futhi izinga lokushisa likhuphuka ngenhla kwama-80 ° C. Uma okuqukethwe kuqukethe inani elikhulu le-zinc yensimbi, kuzokhiqizwa inani elikhulu le-hydrogen. Ngakho-ke, i-reactor kumele ifakwe idivaysi enamandla yokuphelelwa amandla. Ukuze usheshise isilinganiso sokuphendula esigabeni sakamuva sokusabela, izinto eziqukethe ngokweqile zeZinc-eziqukethe. Inani le-PH ekugcineni kokuphendula lilawulwa cishe ngo-5.1, futhi ama-slurry acacisiwe futhi ahlungwa. Okuqukethwe kwe-Zinc ku-Filter Residif kufanele kube ngaphansi kwama-5%. Ngaphezu kwe-zinc sulfate, i-filtrate iqukethe futhi i-sulfate ihambelana nokungcola kwensimbi ezintweni zokwenziwa eziluhlaza. Ukususa ukungcola kungenziwa ngezinyathelo ezimbili. Okokuqala, ithusi, i-nickel, njll. Kususwe, bese kususwa insimbi. I-filtrate ifudunyezwa ku-80 ° C in the sangali, i-zinc powder iyangezwa, futhi ingxube ivuswe ngamandla amahora ama-4 kuye kwangama-6. Njengoba i-zinc inekhono lokunciphisa eliphansi kune-zethusi, i-nickel kanye ne-cadmium, lezi zinsimbi zingahanjiswa kwikhambi. Ifomula yokuphendula imi kanjena:
ZN + CUSO4 → ZNSO4 + Cuzn + Niso4 → ZNSO4 + ZNN + CDSO4 → ZNSO4 + CD
Isixazululo esithathelwe esikhundleni sihlungwa yingcindezi yokususa i-Slag yensimbi enodaka enhle. I-Filtrate ithunyelwa esitsheni se-oxidation, ifudunyezwa ku-80 ° C, kanye ne-sodium °crbaclorite, i-potassium permanganate, i-manganese i-dioxide, njll. Ngemuva kwe-oxidation, kufakwa inani elifanele le-lime. Ubisi lokuqalisa i-iron hydroxide ephezulu bese uyihlunga. Lapho usebenzisa i-bleaching powder, ubilise ikhambi ngemuva kokunambukayo ukubhubhisa i-bleaching powder esele. Lapho usebenzisa i-potassium permanganate, i-zinc oxide ingangezwa ukulungisa inani le-PH yekhambi liye ku-5.1 ngenxa yemvula ye-acid yamahhala. I-Filtrate igxile ngokuhwamuka, ipholile ngaphansi kuka-25 ° C, kanye ne-zinc sulfate heptahydrate znso4 · Ama-crystal4 ·h2 amakristalu, angenawo amanzi emzimbeni.
