The main application is as a coagulant in the production of rayon. It is also a precursor to the pigment lithopone. Zinc sulfate is used to supply zinc in animal feeds, fertilizers, and agricultural sprays. Zinc sulfate, like many zinc compounds, can be used to control moss growth on roofs. It is used as in electrolytes for zinc plating, as a mordant in dyeing, as a preservative for skins and leather and in medicine as an astringent and emetic. Minerals As a mineral ZnSO4·7H2O is known as goslarite. Zinc sulfate occurs as several other minor minerals Zinc-melanterite (Zn,Cu,Fe)SO4·7H2O (structurally different from goslarite). Lower hydrates of zinc sulfate are rarely found in nature: (Zn,Fe)SO4·6H2O (bianchite), (Zn,Mg)SO4·4H2O (boyleite), and (Zn,Mn)SO4·H2O (gunningite).

It is mainly used in the production of man-made fibril concretion, and also used as intermediary dyed reagent in the dying field. 2. it works as fertilizer and animal feed. Zinc Sulfate functions as activator in the medicine industry. 3.The food grade product can be used as nutritious supplement,etc. 4. Zinc sulfate is a significant material of zinc compound,dye,lithopone, in-zinc activator, electrolysed zinc, electroplated zinc, and also mucilage glue fibre.In addition, it functions as preserving material of wood and leather.
