Kodi zinc sulphate pazakudya zamchere ndi mfundo zake zogwirira ntchito ndi ziti?

Ntchito yayikulu ya zinc sulphate pakukonza mchere ndikusankha zinc ores ndikukana mchere wokhala ndi zinc.Nthawi zambiri, imakhala ndi kukana bwino mu alkaline slurry.Kukwera kwa pH ya slurry, ndipamenenso kukana kumakhala koonekeratu, komwe kumapindulitsa pakukonza mchere.Ndiwonso amagwiritsidwa ntchito nthawi zambiri mchere wopangira mchere wokhala ndi mtengo wotsika komanso zotsatira zabwino.Ndi chinthu chofunika kwambiri mu mineral processing.
Mfundo ya zinc sulphate: Zinc sulphate yoyera ndi galasi loyera, losungunuka mosavuta m'madzi, ndipo ndi inhibitor ya sphalerite.Nthawi zambiri amangokhala ndi zoletsa zamchere slurry.Kukwera kwa pH ya slurry, m'pamenenso zikuwonekeratu kuti zimalepheretsa..Zinc sulphate imapanga zotsatirazi m'madzi:
ZnSO4＝Zn2++SO42-
Zn2++2H20=Zn(OH)2+2H+
Zn(OH)2 ndi gulu la amphoteric lomwe limasungunuka mu asidi kupanga mchere.
Zn(OH)2+H2S04＝ZnSO4+2H2O
Mu alkaline sing'anga, HZnO2- ndi ZnO22- amapezeka.Kutengera kwawo ku mchere kumawonjezera hydrophilicity ya mchere pamalo.
Zn(OH)2+NaOH=NaHZnO2+H2O
Zn(OH)2+2NaOH=Na2ZnO2+2H2O
