Yiziphi izici ezijwayelekile ze-zinc sulfate yokucubungula izimbiwa kanye nesimiso sayo sokusebenza?

Indima eyinhloko ye-zinc sulfate ekusetshenzisweni kwamaminerali ukukhetha ama-zinc ores kanye nokumelana namaminerali aqukethe i-zinc.Ngokuvamile, inokumelana kangcono ne-alkaline slurry.Lapho inani le-pH liphakeme le-slurry, kuba sobala kakhulu ukumelana, okuzuzisa ekucutshungulweni kwamaminerali.Kubuye kube yinto evame ukusetshenziswa yokucubungula amaminerali enenani eliphansi kanye nomphumela omuhle.Kuyinto ebalulekile ekusetshenzisweni kwezimbiwa.
Isimiso sesenzo se-zinc sulfate: I-zinc sulfate ehlanzekile iyikristalu emhlophe, incibilika kalula emanzini, futhi iyisivimbeli se-sphalerite.Ivamise ukuba nomphumela ovimbayo kuphela ku-alkaline slurry.Uma iphezulu i-pH ye-slurry, umphumela wayo ovimbelayo ubonakala kakhulu..I-Zinc sulfate ikhiqiza ukusabela okulandelayo emanzini:
I-ZnSO4＝Zn2++SO42-
Zn2++2H20=Zn(OH)2+2H+
I-Zn(OH)2 iyinhlanganisela ye-amphoteric encibilika ku-asidi ukwenza usawoti.
I-Zn(OH)2+H2S04＝ZnSO4+2H2O
Nge-alkaline medium, i-HZnO2- ne-ZnO22- iyatholakala.Ukukhangisa kwawo kumaminerali kuthuthukisa i-hydrophilicity yezindawo zamaminerali.
Zn(OH)2+NaOH=NaHZnO2+H2O
Zn(OH)2+2NaOH=Na2ZnO2+2H2O
