Indima ephambili ye-zinc sulfate ekuqhutyweni kweeminerali kukukhetha i-zinc ores kunye nokuxhathisa amaminerali aqukethe i-zinc.Ngokuqhelekileyo, inokumelana okungcono kwi-alkaline slurry.Ukuphakama kwexabiso le-pH ye-slurry, kubonakala ngakumbi ukuchasana, okuluncedo ekuqhutyweni kweeminerali.Ikwayinto esetyenziswa ngokuqhelekileyo i-mineral processing material enexabiso eliphantsi kunye nesiphumo esihle.Yimathiriyeli ebalulekileyo ekuqhutyweni kweeminerali.
Umgaqo wesenzo se-zinc sulfate: I-zinc sulfate ecocekileyo yikristale emhlophe, i-soluble kalula emanzini, kwaye iyi-inhibitor ye-sphalerite.Idla ngokuba nefuthe lokuthintela kwi-alkaline slurry.Ukuphakama kwe-pH ye-slurry, kuyabonakala ngakumbi umphumo wayo wokuthintela..I-Zinc sulfate ivelisa oku kusabela kulandelayo emanzini:
ZnSO4＝Zn2++SO42-
Zn2++2H20=Zn(OH)2+2H+
I-Zn(OH)2 yikhompawundi ye-amphoteric enyibilika kwiasidi ukwenza ityuwa.
Zn(OH)2+H2S04＝ZnSO4+2H2O
Kwi-alkaline medium, i-HZnO2- kunye ne-ZnO22- ifunyenwe.Ukubhengezwa kwabo kwiiminerali kwandisa i-hydrophilicity ye-mineral surfaces.
Zn(OH)2+NaOH=NaHZnO2+H2O
Zn(OH)2+2NaOH=Na2ZnO2+2H2O
