Babban aikin zinc sulfate a cikin sarrafa ma'adinai shine zaɓar ma'adinan zinc da tsayayya da ma'adanai masu ɗauke da zinc.Yawancin lokaci, yana da mafi kyawun juriya a cikin slurry alkaline.Mafi girman ƙimar pH na slurry, mafi mahimmancin juriya shine, wanda ke da amfani ga sarrafa ma'adinai.Har ila yau, kayan aikin ma'adinai ne da aka saba amfani da shi tare da ƙananan farashi da tasiri mai kyau.Abu ne mai mahimmanci a cikin sarrafa ma'adinai.
Ka'idar aikin zinc sulfate: Zinc sulfate mai tsabta shine farin crystal, mai sauƙin narkewa cikin ruwa, kuma shine mai hana sphalerite.Yawancin lokaci kawai yana da tasirin hanawa a cikin slurry alkaline.Mafi girman pH na slurry, mafi bayyane tasirin hanawa..Zinc sulfate yana haifar da sakamako mai zuwa a cikin ruwa:
ZnSO4＝Zn2++SO42-
Zn2++2H20=Zn(OH)2+2H+
Zn (OH) 2 fili ne na amphoteric wanda ke narkewa cikin acid don samar da gishiri.
Zn(OH)2+H2S04＝ZnSO4+2H2O
A cikin matsakaici na alkaline, ana samun HZnO2- da ZnO22-.Su adsorption zuwa ma'adanai kara habaka da hydrophilicity na ma'adinai saman.
Zn(OH)2+NaOH=NaHZnO2+H2O
Zn(OH)2+2NaOH=Na2ZnO2+2H2O
