Zinc sulfate monohydrate is used in calico-printing, preserving wood and skins, electrolytes for zinc plating, bleaching paper and clarifying glue. It is also used as a chemical reagent, coagulant in the preparation of rayon, mordant in dyeing and as a zinc source in animal feeds. In medicine, it is used as an astringent and emetic. Further, it is a precursor to the pigment lithopone. In addition to this, it is used to supply zinc in fertilizers, agricultural sprays, in electrolytes for zinc plating and as a mordant in dyeing.
